Miscellaneous Tips & Tricks

How to redirect your log entries to the syslog

You just need to add some lines to your logback.xml.

Like:

<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
   <syslogHost>localhost</syslogHost>
   <facility>AUTH</facility>
   <suffixPattern>{}openhab: [%thread] %logger %msg</suffixPattern>
</appender>
    
<root level="INFO">
   <appender-ref ref="SYSLOG" />
</root>

How to do a proper ICMP ping on Linux

Java is not capable to open a raw socket to do a ICMP ping (see https://code.google.com/p/openhab/issues/detail?id=134). As a workaround, you can use the exec binding on Linux:

Switch PingedItem { exec="<[/bin/sh@@-c@@ping -c 1 192.168.0.1 | grep \"packets transmitted\" | sed -e \"s/.*1 received.*/ON/\" -e \"s/.*0 received.*/OFF/\":30000:REGEX((.*))]" }

How to add current or forecast weather icons to your sitemap

This example gets the weather information from the Wunderground online api service (for details see http://www.wunderground.com/weather/api/) and shows the current weather icon and weather state (such as partly cloudy) in one line like it would show any other Openhab item.

  • in the items file, create a string as follows:
    String w   "Today [%s]"   <w>  { http="<[http://api.wunderground.com/api/<your api key>/forecast/q/Luxembourg/Luxembourg.xml:3600000:XSLT(wunderground_icon_forecast.xsl)]"}

  • copy the weather icons to your images folder and rename and convert them to png, e.g. "w-partly_cloudy.png". The weather icon sets can be found here:

    http://www.wunderground.com/weather/api/d/docs?d=resources/icon-sets

  • create a stylesheet named wunderground_icon_forecast.xsl containing the following lines (place it under configurations/transform):

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">       
   <xsl:output indent="yes" method="xml" encoding="UTF-8" omit-xml-declaration="yes" />
   <xsl:template match="/">
      <!-- format: hh:mm:ss -->
      <xsl:value-of select="//response/forecast/txt_forecast/forecastdays/forecastday/icon/text()" />
   </xsl:template>
</xsl:stylesheet>
  • display the string in the .sitemap file:

Text item=w

Make the script executable and configure it to run on boot.

sudo chmod a+x /etc/init.d/openhab
sudo update-rc.d openhab defaults

Now whenever your Linux machine boots openHAB will be automatically started.

How to configure openHAB as (Gentoo) openRC service

Create the openhab user with

useradd -s /sbin/nologin openhab

and the log directory

mkdir /var/log/openhab && chown openhab /var/log/openhab

then create /etc/(conf|init).d/openhab as below and add it to the default runlevel

rc-update add openhab default

OpenHAB must be installed in /opt/openhab

/etc/init.d/openhab:

         else
          echo "Starting openHAB"
          cd ${OHPATH}
          sudo -u ${OHUSER} screen -S openHAB -dm  sh ./start.sh
        fi
        ;;
  stop)
        echo "Stopping openHAB"
        sudo -u ${OHUSER} screen -S openHAB -p 0 -X stuff "exit$(printf \\r)"
        sudo -u ${OHUSER} screen -S openHAB -p 0 -X stuff "y$(printf \\r)"

        PID=`ps -ef | grep openHAB | grep -v grep | awk '{print $2}'`
        while [ `ps -ef | grep $PID | wc -l` -gt 1 ]
         do
          echo -n .

        N=/etc/init.d/$NAME
        echo "Usage: $N {start|stop|restart}" >&2
        exit 1
        ;;
esac
exit 0

Make the script executable and configure it to run on boot.

sudo chmod a+x /etc/init.d/openhab
sudo update-rc.d openhab defaults

Now whenever your Linux machine boots openHAB will be automatically started in a screen-session called openHAB. To reach the OSGI-Console, just type

sudo -u openhab screen -r openHAB

How to configure openHAB to start automatically on Windows

This setup uses procmon from Apache. Download the binaries from http://www.apache.org/dist/commons/daemon/binaries/windows/. Unzip to the runtime folder Create a install_service.bat file, it will be based on start.bat, see below. I must be adapted to match your version/path to openhab. First time you will have to go into windows services and reenter the login info for the service, this will grant the logon as service right to the user.

How start openHAB automatically on Linux using systemd

Systemd is used as init system on various Linux flavors, i.e. openSUSE, ArchLinux, etc. To make openHAB start automatically on system startup we utilize the main start.sh script which comes with the openHAB distribution. We just need to modify it a bit. Instead of this line:

java -Dosgi.clean=true -Declipse.ignoreApp=true -Dosgi.noShutdown=true -Djetty.port=$HTTP_PORT -Djetty.port.ssl=$HTTPS_PORT -Djetty.home=. -Dlogback.configurationFile=configurations/logback.xml -Dfelix.fileinstall.dir=addons -Djava.library.path=lib -Djava.security.auth.login.config=./etc/login.conf -Dorg.quartz.properties=./etc/quartz.properties -Dequinox.ds.block_timeout=240000 -Dequinox.scr.waitTimeOnBlock=60000 -Dfelix.fileinstall.active.level=4 -Djava.awt.headless=true -jar $cp $* -console

we'll use:

java -Dosgi.clean=true -Declipse.ignoreApp=true -Dosgi.noShutdown=true -Djetty.port=$HTTP_PORT -Djetty.port.ssl=$HTTPS_PORT -Djetty.home=. -Dlogback.configurationFile=configurations/logback.xml -Dfelix.fileinstall.dir=addons -Djava.library.path=lib -Djava.security.auth.login.config=./etc/login.conf -Dorg.quartz.properties=./etc/quartz.properties -Dequinox.ds.block_timeout=240000 -Dequinox.scr.waitTimeOnBlock=60000 -Dfelix.fileinstall.active.level=4 -Djava.awt.headless=true -jar $cp > run.log 2>&1 &

this makes openHAB run in the background and redirect stderr and stdout to a file called run.log. Notice that only the end of the line has changed. You'll also may want to create a copy of the original script file before making the change.

Now here is what we need for systemd: Identify where the service units are placed on your system. In openSUSE it is: /usr/lib/systemd. Now create a new file called openhab.service in this folder: /usr/lib/systemd/system and copy the following into it:

[Unit]
Description=Open Home Automation Bus

[Service]
Type=forking
GuessMainPID=yes
ExecStart=/Space/Apps/openhab/start.sh
ExecStop=/usr/bin/kill -SIGINT $MAINPID
ExecStopPost=
User=openhab
Group=daemon
WorkingDirectory=/Space/Apps/openhab

[Install]
WantedBy=multi-user.target

Adjust the WorkingDirectory and the path to start.sh as you need. Also this unit uses a separate user to run openHAB with. This user must be created first. You can as well start openHAB with your own user account. The Type forking must be used here because of the change we did in the start.sh script.

If that is done "install" the unit: systemctl enable openhab.service

Now start the service: systemctl start openhab.service

You may check if it's running with: systemctl status openhab.service

You should see something this if it's running:

openhab.service - Open Home Automation Bus
   Loaded: loaded (/usr/lib/systemd/system/openhab.service; enabled)

How to configure openHAB to start automatically on MacOSX

Create a new file named org.openhab.daemon.plist in /Library/LaunchDaemons using your preferred editor (e.g. nano) as root user.

$ sudo nano /Library/LaunchDaemons/org.openhab.daemon.plist

Copy the code below.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>GID</key>
        <integer>0</integer>
        <key>Label</key>
        <string>org.openhab.daemon</string>
        <key>OnDemand</key>
        <false/>
        <key>RunAtLoad</key>
        <true/>
        <key>Program</key>
        <string>/Applications/openhab/start.sh</string>
        <key>UserName</key>
        <string>root</string>
        <key>KeepAlive</key>
        <true/>
</dict>
</plist>

Ensure that the file has the correct user.

$ sudo chown root /Library/LaunchDaemons/org.openhab.daemon.plist

The openhab process will now be launched at startup by launchd.

Alternatively it is possible to start the openhab process with the following command:

$ sudo launchctl load -w /Library/LaunchDaemons/org.openhab.daemon.plist

It is also possible to stop the openhab process using the following command:

$ sudo launchctl unload /Library/LaunchDaemons/org.openhab.daemon.plist

Use cheap bluetooth dongles on remote PCs to detect your phone/watch

This is more an idea really but consider that openhab can know your home by picking up on the bluetooth on your phone, using cheap 3 euro bluetooth dongles connected to the various PCs and media centres you may have.

EG On an ubuntu/debian based PC.

  1. Install the "bluez" bluetooth stack.
apt-get install bluez
  1. Use the bash script below to do a simple scan several times per min. This script looks for my phone "jon-phone". Its made no real difference to the battery life on my android 4.x phone. The script updates a switch in openhab called "zoneOneState". You could have as many zones as you need/want to cover your house.
    #!/bin/bash
    
    while true
    do
      DEVICES=`hcitool scan`
    
      if [[ $DEVICES = *jon-phone* ]]
      then
        curl --max-time 2 --connect-timeout 2 --header "Content-Type: text/plain" --request PUT --data "ON" http://192.168.1.121:8080/rest/items/zoneOneState/state
      else
        curl --max-time 2 --connect-timeout 2 --header "Content-Type: text/plain" --request PUT --data "OFF" http://192.168.1.121:8080/rest/items/zoneOneState/state
      fi
    
      sleep 30
    done

  1. The rule governing the decision process on if your house is occupied can be as complex or simple as you need. The rule below is clunky but simple and gets the job done. It uses three zone switches to decide if it should set a switch called "occupiedState" to on or off. Then using the occupiedState switch you can make your other openhab rules behave in different ways. Each zone checked reports true if your bluetooth device has been seen within the last 5 mins (helps stop flap caused by the patchy coverage of bluetooth signals).

    //FIGURE IF HOUSE OCCUPIED EVERY 30 SECONDS rule "check occupiedState" when Time cron "*/30 * * * * ?" then if (occupiedState.state == ON) { zoneOneFlag = true zoneTwoFlag = true zoneThreeFlag = true

     	if (zoneOneState.state == OFF)
 	{

Check presence by detecting WiFi phones/tablets

This is a small modification to the tip above. This time we check, whether somebody is at home by testing if their phone is within WiFi reach. All you need is the Network Health Binding.

Your items file could look like this:

Group gMobiles
Switch Presence
Switch phone1 (gMobiles) {nh="android-xxxxx"}
Switch phone2 (gMobiles) {nh="android-yyyyy"}

My rules file looks like this:

rule "Periodically check presence"
when
    Time cron "0 */5 * * * ?"
then
        if (Presence.state == ON)
        {
                if(gMobiles.members.filter(s | s.state == ON).size == 0) {
                        logInfo("PresenceCheck", "No phone within reach, checking for flapping")
                        if(gMobiles.members.filter(s | s.changedSince(now.minusMinutes(5))).size == 0) {
                                logInfo("PresenceCheck", "Nobody is at home")
                                sendCommand(Presence, OFF)
                        }
                }
        }
        else
        {
                //For initialisation. If Presence is undefined or off, although it should be on.
                if(gMobiles.members.filter(s | s.state == ON).size > 0) {
                        sendCommand(Presence, ON)
                }
                else if (Presence.state == Undefined || Presence.state == Uninitialized) {
                        sendCommand(Presence, OFF)
                }
        }

end

rule "Coming home"
when
        Item gMobiles changed
then
        if (Presence.state != ON) {
                if(gMobiles.members.filter(s | s.state == ON).size > 0) {
                        logInfo("PresenceCheck", "Somebody is home")
                        sendCommand(Presence, ON)
                }
        }
end

Presence is only switched off, if no phone was seen within the last 5 minutes. This avoids flapping, if you are just taking out the trash or something.

Additionally to the Network Health items in the gMobiles group, you could add bluetooth devices (like used above) or motion sensors.

Get connection status of all network devices from Fritz!Box, eg for presence detection

For cases where bluetooth detection described above or network health binding is not suitable.

Requirements

  • Fritz!Box with telnet access
  • Linux server (preferably the openHAB server), tested with ReadyNAS
  • Linux knowledge to adopt scripts

Methodology

  • Shell script on the Fritz!Box to dump all known network devices with their current connection status
  • This script is called from the Linux server through a cron job periodically (eg every minute), parses the dump and updates openHAB items according to their connection status

Restrictions

  • Only tested on ReadyNAS Linux with manual added packages, others might need adoption
  • All parameters like login/password/paths/script names "hard-coded" into the scripts, need adoption
  • Absolutely no error-checks, use at own risk
  • Due to these restrictions only applicable for people with at least basic Linux knowledge

How-To

On the Fritz!Box

The Fritz!Box shows a reliable status of devices connected to the network using the built-in ctlmgr_ctl r landevice command (see http://www.wehavemorefun.de/fritzbox/Landevice).

Create the script landevices.sh permanently (should not be deleted at reboot), for example in folder /var/media/ftp/Fritz!Box/. Make it executable. Take care not to indent the script as the Fritz!Box does not like that.

    #!/bin/sh
    i=0
    count_devices=`ctlmgr_ctl r landevice settings/landevice/count`
    while [ $i -lt $count_devices ]
    do
    device="landevice="$i
    #for command in name ip mac manu_name dhcp static_dhcp wlan ethernet active online speed deleteable wakeup source neighbour_name is_double_neighbour_name ipv6addrs ipv6_ifid
    for command in name active
    do
    output="`ctlmgr_ctl r landevice settings/landevice$i/$command`"
    device=$device" "$command"="$output
    done
    echo $device
    i=`expr $i + 1`
    done

The commented out for loop shows all possible subcommands, so it is also possible to output eg the speed or mac adress of all landevices. However this would also require a change on the calling script below. Once created on the Fritz!Box and executed it should provide you all known network devices with their current status:

    # ./landevices.sh
    landevice=0 name=BoyLaptop active=0
    landevice=1 name=BoyPhone active=0
    landevice=2 name=BoyiPod active=0
    landevice=3 name=DGOfficePrinter active=1
    landevice=4 name=DGTVRasPlex active=1
    landevice=5 name=DGTVWii active=0
    landevice=6 name=DadLaptop active=0
    landevice=7 name=DadLaptopWork active=0
    landevice=8 name=DadLaptopWork active=0
    landevice=9 name=DadPC active=1
    landevice=10 name=DadPhone active=1
    landevice=11 name=DadPhoneWork active=1
    landevice=12 name=EGEntranceAP active=1
    landevice=13 name=EGTVRasPlex active=1
    landevice=14 name=EGWZAP active=0
    landevice=15 name=GirlLaptop active=0
    landevice=16 name=GirlPhone active=1
    landevice=17 name=GuestLaptop active=0
    landevice=18 name=KGOfficePrinter active=1
    landevice=19 name=KGOfficeReadyNAS active=1
    landevice=20 name=KGTEC1AP active=1
    landevice=21 name=KGTEC2AP active=1
    landevice=22 name=MomLaptop active=0
    landevice=23 name=MomLaptop active=0
    landevice=24 name=MomLaptopWork active=0
    landevice=25 name=MomPhone active=0

If required, use the Fritz!Box GUI to give the devices some reasonable names in order to easily assign phones/laptops etc to people or media devices to floors/rooms. Using the ctlmgr_ctl command it would also be possible to only query for specific devices (go through the full list and look for either name or mac or both), but any change in the output of this script requires changes on the other end as well.

On the Linux server

Create a expect script in a folder on your Linux Server and make it executable. The only purpose of this script is only to connect to your Fritz!Box through a telnet session and call the script created there.

    #!/usr/bin/expect
    spawn telnet <<<your fritzbox ip here>>>
    expect "user: "
    send "<<<your fritzbox login here>>>\r"
    expect "password: "
    send "<<<your fritzbox password here>>>\r"
    expect "telnet"
    expect "#"
    send "\r"
    expect "#"
    send "/var/media/ftp/Fritz!Box/landevices.sh\r"
    expect "#"
    send "exit 0\r"

Here the IP of the Fritz!Box, your credentials and the path to the script need to be adopted. Furthermore the above script is for the newest version of the Fritz!box firmware where multiple user accounts can be created. In case this is not your case, you have to omit the "user:" and "login" expect/send statements in the script above, as in that case the Fritz!Box telnet session only requires the password, not the user. Again, to validate the functionality just execute the script:

    ReadyNAS:~# ./fritzbox_devices.expect
    spawn telnet 192.168.178.1
    
    Entering character mode
    Escape character is '^]'.
    
    Fritz!Box user: admin
    password:
    
    
    BusyBox v1.20.2 (2013-05-13 12:53:07 CEST) built-in shell (ash)
    Enter 'help' for a list of built-in commands.
    
    ermittle die aktuelle TTY
    tty is "/dev/pts/1"

    #
    # /var/media/ftp/Fritz!Box/landevices.sh
    landevice=0 name=BoyLaptop active=0
    landevice=1 name=BoyPhone active=0
    landevice=2 name=BoyiPod active=0
    landevice=3 name=DGOfficePrinter active=1
    landevice=4 name=DGTVRasPlex active=1
    landevice=5 name=DGTVWii active=0
    landevice=6 name=DadLaptop active=0
    landevice=7 name=DadLaptopWork active=0
    landevice=8 name=DadLaptopWork active=0
    landevice=9 name=DadPC active=1
    landevice=10 name=DadPhone active=1
    landevice=11 name=DadPhoneWork active=1
    landevice=12 name=EGEntranceAP active=1
    landevice=13 name=EGTVRasPlex active=1
    landevice=14 name=EGWZAP active=0
    landevice=15 name=GirlLaptop active=0
    landevice=16 name=GirlPhone active=1
    landevice=17 name=GuestLaptop active=0
    landevice=18 name=KGOfficePrinter active=1
    landevice=19 name=KGOfficeReadyNAS active=1
    landevice=20 name=KGTEC1AP active=1
    landevice=21 name=KGTEC2AP active=1
    landevice=22 name=MomLaptop active=0
    landevice=23 name=MomLaptop active=0
    landevice=24 name=MomLaptopWork active=0
    landevice=25 name=MomPhone active=0
    # ReadyNAS:~#

As you can see here we have the original output of the script plus some "overhead" for the telnet session.

Now create a sed script fritzbox_devices.sed that will create curl commands to interface with the openHAB server:

    #!/bin/sed -f
    s#\r$##
    s#landevice=[0-9]* name=#curl --silent -H \"Content-Type: text/plain\" http://localhost:8080/rest/items/landevice_#g
    s#active=0#-d \"OFF\"#g
    s#active=1#-d \"ON\"#g

The first line here is just to eliminate "DOS-like" \r at the end of each line which show up with a ReadyNAS as server and might not be required in your setup, but you can still leave them. The second line replaces the "landevice=....name=...... with a curl command. In order to have reasonable variable names again in openHAB the landevices there start with "landevice_", so "DadPhone" on the Fritz!Box gets landevice_DadPhone in openHAB. Furthermore localhost:8080 needs to be changed to match your openHAB server if is not running on the same machine. The last two lines replace the "active=0" or "active=1" with the correct statements for curl.

Another validation of the scripts created so far:

ReadyNAS:~# ./fritzbox_devices.expect | fgrep "landevice=" | ./fritzbox_devices.sed
curl --silent -H "Content-Type: text/plain" http://localhost:8080/rest/items/landevice_BoyLaptop -d "OFF"

Configuration in openHAB

Now it is time to create the required items in openHAB - One Switch for each landevice that is supposed to be used later. In case you don't configure all landevices as items you will get error messages in openHAB logs, however these can be ignored. Just to have a "clean" configuration you might want to add all devices.

Switch landevice_KGOfficeReadyNAS  "ReadyNAS"                       <network> (KG_TEC1, gNetworkServer)
Switch landevice_EGEntranceAP      "Airport Erdgeschoss"            <network> (gWZ, gNetworkServer)
Switch landevice_EGWZAP            "Airport Repeater Erdgeschoss"   <network> (gWZ, gNetworkServer)
Switch landevice_KGTEC1AP          "Airport Keller TEC1"            <network> (KG_TEC1, gNetworkServer)		
Switch landevice_KGTEC2AP          "Airport Keller TEC2"            <network> (KG_TEC2, gNetworkServer)
Switch landevice_DGOfficePrinter   "Drucker Dachgeschoss"           <network> (DG_GUEST, gNetworkMedia)
Switch landevice_KGOfficePrinter   "Drucker Keller"                 <network> (KG_TEC1, gNetworkMedia)
Switch landevice_DGTVRasPlex		"RasPLEX Dachgeschoss"	<network> (DG_TV, gNetworkMedia)
Switch landevice_EGTVRasPlex		"RasPLEX Erdgeschoss"	<network> (EG_TV, gNetworkMedia)
Switch landevice_DGTVWii		"Wii"			<network> (DG_TV, gNetworkMedia)
Switch landevice_DadPC			"Dad PC"		<network> (gWZ, gNetworkDad)
Switch landevice_DadLaptop		"Dad Laptop"		<network> (gWZ, gNetworkDad)
Switch landevice_DadPhone		"Dad Phone"		<network> (gWZ, gDAD_PRESENT, gNetworkDad, gPhones)
Switch landevice_DadLaptopWork	        "Dad Laptop@work"	<network> (gWZ, gNetworkDad)
Switch landevice_DadPhoneWork	        "Dad Phone@work"	<network> (gWZ, gDAD_PRESENT, gNetworkDad, gPhones)
Switch landevice_MomLaptop		"Mom Laptop"		<network> (gWZ, gNetworkMom)
Switch landevice_MomPhone		"Mom Phone"		<network> (gWZ, gMOM_PRESENT, gNetworkMom, gPhones)
Switch landevice_MomLaptopWork	        "Mom Laptop@work"	<network> (gWZ, gNETWORKMom)
Switch landevice_MomPhoneWork	        "Mom Phone@work"	<network> (gWZ, gMOM_PRESENT, gNetworkMom, gPhones)
Switch landevice_GuestLaptop	        "Guest Laptop"		<network> (DG_GUEST, gNetworkGuest)
Switch landevice_GuestPhone		"Guest Phone"		<network> (DG_GUEST, gGUEST_PRESENT, gNetworkGuest, gPhones)
Switch landevice_GirlLaptop		"Girl Laptop"		<network> (DG_GIRL, gNetworkGirl)
Switch landevice_GirlPhone		"Girl Phone"		<network> (DG_GIRL, gGIRL_PRESENT, gNetworkGirl, gPhones)
Switch landevice_BoyLaptop		"Boy Laptop"		<network> (DG_BOY, gNetworkBoy)
Switch landevice_BoyPhone		"Boy Phone"		<network> (DG_BOY, gBOY_PRESENT, gNetworkBoy, gPhones)
Switch landevice_BoyiPod		"Boy iPod"		<network> (DG_BOY, gNetworkBoy)

As you can see the devices are assigned to various groups in the config, the interesting ones are the "_PRESENT" ones for the phones. Based on these with rules the status of each person's presence in the house can be defined. In my case when at least one phone per kid/guest is active in the network this person is seen as "present", for mom and dad both devices have to be present (on the weekends the work phones usually stay connected at home). Adding all devices here also offers some other capabilities... For example lower the download speed of the download server based on the number of active laptops in case the internet connection is not lighting fast.

Final steps on the Linux server

Another test: Now execute one of the curl statements created in the previous step on the Linux server in the shell:

ReadyNAS:~# curl --silent -H "Content-Type: text/plain" http://localhost:8080/rest/items/landevice_KGTEC2AP -d "ON"
ReadyNAS:~#

If the items were created correctly this should generate no output at all in the Linux shell, but show up promptly in the openHAB event log:

ReadyNAS:~# tail -200 /opt/openhab/logs/events.log
...
2013-11-13 22:47:25 - landevice_KGTEC2AP received command ON
...

Now create the final script fritzbox_devices.sh on the Linux server

#!/bin/sh
/root/fritzbox_devices.expect | /bin/fgrep "landevice=" | /root/fritzbox_devices.sed > /tmp/commands.txt
. /tmp/commands.txt
rm /tmp/commands.txt

and test this script again, this time using time to avoid too many calls by cron:

ReadyNAS:~# time ./fritzbox_devices.sh
real    0m13.637s
user    0m0.267s
sys     0m0.202s
ReadyNAS:~#

Again, you should see no output in case you defined all items in openHAB. In case you did not errors will show up here and in the openHAB logs. A "clean" openHAB event.log outputs looks as follows:

ReadyNAS:~# tail -200f /opt/openhab/logs/events.log
...

When everything is working fine the cronjob can be set up, but avoid calling the script to frequently (thus the time before). In this case we set it up to run each minute:

# m h  dom mon dow   command
* * * * * /root/fritzbox_devices.sh

(Yet) incomplete snipplets with additional functionalities for the Fritz!Box

wlandevices.sh is just dumping all devices connected directly to the wlan of the Fritz!Box (not those attached through LAN ports, but including the guest WLAN). For example to show devices connected to the guest WLAN with their remaining time in the openHAB GUI:

#!/bin/sh
i=0
count_devices=`ctlmgr_ctl r wlan settings/wlanlist/count`
while [ $i -lt $count_devices ]
do
device="wlandevice="$i
#for command in mac UID state speed rssi quality is_turbo is_guest is_ap ap_state mode wmm_active cipher powersave is_repeater channel freq flags flags_set
for command in mac state speed is_guest
do
output="`ctlmgr_ctl r wlan settings/wlanlist$i/$command`"
device=$device" "$command"="$output
done
echo $device
i=`expr $i + 1`
done

The output looks as follows and again can be adopted using the commented out for loop:

# ./wlandevices.sh
wlandevice=0 mac=AC:81:12:B0:39:F0 state=0 speed=0 is_guest=0
wlandevice=1 mac=20:02:AF:89:59:29 state=0 speed=0 is_guest=0

When you want to refer to device names, the mac addresses need to be added to the output of landevices.sh above and the output of both scripts needs to be matched by mac address which should be easily possible.

Furthermore wlanstatus.sh just dumps the status of the wireless networks of the Fritz!Box:

#!/bin/sh
for wlan in "" guest_
do
device=$wlan"wlan: "
for command in ap_enabled ssid pskvalue time_remain
do
output="`ctlmgr_ctl r wlan status/$wlan$command`"
device=$device" "$command"="$output
done
echo $device
done

The output looks as follows:

# ./wlanstatus.sh
wlan: ap_enabled=1 ssid=wlanssid pskvalue=unencryptedpassword time_remain=
guest_wlan: ap_enabled=0 ssid=guestssid pskvalue=unencryptedpassword time_remain=0

This script might be used together with another (yet to do) guest wlan on/off script to offer kids the possibility to enable/disable the guest wlan with a randomly generated password (eg *echo tr -dc A-Za-z0-9* < /dev/urandom | head -c 16_) in order to not have to do this yourself each time.

Use Fritzbox SIP Feature to make a call in case of an event

Prologue: This Guide shows you how to make a call with a sip-client over a fritz box. But it should work with all other sip gateways as well – give it a try!

Requirements:

  • AVM Fritzbox (tested with 7490)
  • openhab (obviously)
  • soundcard (dummy is ok if you don’t have one. Give ALSA a try)
  • sipcmd
  • a couple of wav-files (8kHz, 16 bit per Sample, PCM)
  • the power of Copy and Paste ;-)

First of all, add a new ip phone to your fritzbox by doing this:

(note: I only got a german Version of FritzOS: which means its freely translated to English by me; don’t hit me if says something else on your box :-)

  1. Logon to your fritz.box
  2. On the left, click on "telephony" (GER: Telefonie)
  3. Next, click on "devices" (GER: Telefonie-Geräte)
  4. On the right site at the bottom, click on "Create a new device" (GER: Neues Gerät einrichten)
  5. Now select “Phone” (GER: Telefon (mit und ohne Anrufbeantworter)) and click next.
  6. Select "LAN/WiFi (IP-Phone))" (GER: LAN/WLAN (IP-Telefon)) and enter a name for this device. Click next to continue.
  7. Enter a Username (mostly a 3 Digit value; the internal Phone number) and enter a password. Click next.
  8. Now select the outgoing caller-id and carry on.
  9. Next, select "accept only calls for the following numbers" and deselect all numbers. Almost there.
  10. Last step: apply the Settings. DONE! Congrats!

Moving on to SIPCMD:

Did I mention that you need a sound card? Don’t got one? Pah, no probs. ALSA (http://www.alsa-project.org/main/index.php/Main_Page) got your back. Under Debian just install alsa-base "apt-get install alsa-base".

  1. Download the SIPCMD Branch:
    wget https://github.com/tmakkonen/sipcmd/archive/master.zip
  2. Unzip it. Go into the sipcmd-master directory
    needed Packages:
    apt-get install libopal-dev libpt-dev
    (more infos: https://github.com/tmakkonen/sipcmd)
  3. Now just run “make”
  4. Copy the sipcmd. To your preferd BIN Dir (/bin or /usr/bin)
  5. That’s it.

Now go and Record some Wav-Files! You’ll need them later… you also could use text-to-speech engines to get some wav-files – be free.

Put them in this Directory: /opt/openhab/etc/sipcalls/

Create a "Script" with your favourite Text Editor (like nano, vi and so on) for each Event you want to cover.

Example:

/opt/openhab/etc/sipcalls/sipcall_alarm_window_bathroom.sh

Now put this line in:

 sipcmd -u 621 -c verysecurepassord -P sip -w fritz.box -x "c012345678;ws500;vwindow_bathroom.wav;h"

(If you want to call another number, just copy and paste the line above as often as you want.)

Explanation:

-u is the username – mostly a 3 digit number (see Point 7. From the fritzbox setup)
-c is the password you enterd earlier
-P is the Protocol which is used (SIP)
-w is the SIP-Domain; in this case fritz.box
-x the commad that sipcmd should execute where:
C= is the number which should be called
ws= waittime in milliseconds: meaning wait for x millis after the remote party answerd the call before playing the wav-file
v= filename of the wav-file
H= hangup after the file played

Now we just need to define an Item (in /opt/openhab/configurations/items/*.items )

  Switch   SIPCALL_WINDOW_BATHROOM   "SipCall Window Bathroom INTERNAL"   { exec="ON:/opt/openhab/etc/sipcalls/sipcall_alarm_window_bathroom.sh "}

Finally, create a Rule which uses the item:

  Rule "Window_Bathroom_opened"
  when 
  Item WINDOW_BATHROOM received update OPEN
  then
  If (ALARMSYSTEM_ACTIVE.state == ON)
  {
  sendCommand( SIPCALL_WINDOW_BATHROOM, ON)
  // the sendMail command is just another way to get notified
  sendMail("mymail@adresss.com", "OpenHab: Window Bathroom opened!", "please check!")
  }
  End

Thats it.

How to configure openHAB to connect to device symlinks (on Linux)

When connecting serial devices to Linux (i.e. USB) they are assigned arbitrary device names - usually something like /dev/ttyUSB0. There is no way to know exactly what name will be assigned each time you plug in the device however.

Using udev rules you can setup symlinks which are created when the system detects a device is added. The symlink allows you to assign a 'known' name for that device. See this link for a useful tutorial about udev - http://www.reactivated.net/writing_udev_rules.html.

So for example, if you have a ZWave USB dongle you can configure a symlink called /dev/zwave. This makes it much easier to configure connection properties since this name will never change.

However the RXTX serial connection library used in openHAB is unable to 'see' these symlinks. Therefore you need to inform RXTX about your symlinks using a system property.

You can either add the property to the Java command line by adding the following (device names delimited by :

-Dgnu.io.rxtx.SerialPorts=/dev/rfxcom:/dev/zwave

Or add a gnu.io.rxtx.properties file which is accessible in the Java classpath. See http://create-lab-commons.googlecode.com/svn/trunk/java/lib/rxtx/README.txt for more details.

This applies to any openHAB binding that uses the RXTX serial connection library - i.e. RFXCOM, ZWave etc.

Use URL to manipulate items

When you have a device unable to send REST requests (f.e. Webcams), you may use

http://<openhab-host>:8080/CMD?<item>=<state>

Example:

http://<openhab-host>:8080/CMD?Light=ON
http://<openhab-host>:8080/CMD?Light=OFF
http://<openhab-host>:8080/CMD?Light=TOGGLE

TOGGLE changes the current status of a switch item from ON to OFF or from OFF to ON.

Extract caller and called number from Fritzbox Call object

If you define an item like the following in your site.items config

Call   Incoming_Call_No   "Caller No. [%2$s]"   (Phone)   { fritzbox="inbound" }

the Type CallType with its associated methods can be used to extract the caller and called number of the call. The following rule sends an email with both numbers in the subject line.

import org.openhab.library.tel.types.CallType

rule "inbound Call"
  when Item Incoming_Call_No received update
then 
  var CallType call = Incoming_Call_No.state as CallType
  var String mailSubject =
  "Anruf von Nummer " + call.origNum + " -> " + call.destNum
  sendMail( "us...@domain.de" , mailSubject , "");
end

Item loops with delay

Some integrations don't like to be rushed with a cascade of simultaneous commands. This can be an issue if you, for instance want to implement a rule which loops through a list of group members (items) and send a command to all of them, e. g. OFF. The solution is to add a small delay between each command. The example below executes OFF for all members at a one second interval. Use now.plusMillis(i*n) for n millisecond intervals.

rule "Lights out"
when 
	Time cron "0 0 22 ? * MON-THU,SUN *" or
	Time cron "0 59 23 ? * FRI,SAT *"
then 
	gLightOffNight?.members.forEach(item,i|createTimer(now.plusSeconds(i)) [|sendCommand(item, OFF)])
end

enocean binding on Synology DS213+ (kernel driver package)

The enocean binding works with the enocean USB300 usb-stick. To enable the USB300 on a Synology DS213+ (probably works also on Synology DS413 - same CPU...) two things are needed:

  1. The kernel drivers
    usbserial, ftdi_sio and cdc-acm are already included in DSM 4.3
    pl2303 and cp210x are in the package usb-driver-kernel-2.6.32-dh-syno-qoriq-0.001.spk
    The package is stored at OpenHAB google groups and on the package server https://www.hofrichter.at/sspks
    You can install this package in DSM via the package manager -> manual installation or by adding https://www.hofrichter.at/sspks/ to your package sources - there is a tutorial on the Synology support pages about how to do that.
  2. nrjavaserial
    OpenHab 1.3.1 comes with the latest stable version of [nrjavaserial 3.8.8] (https://code.google.com/p/nrjavaserial/) (at the moment (17.11.2013)).
    It's in {openhab_root}/server/plugins/org.openhab.io.transport.serial
    The newer unstable nrjavaserial 3.9.1 is needed for the qoric cpu of the DS213+ and included in the (otherwise unchanged) org.openhab.io.transport.serial_1.3.1.201309182025.jar.
    Just put that file in {openhab_root}/server/plugins/ and delete the original file {openhab_root}/server/plugins/org.openhab.io.transport.serial...

How to use openHAB to activate or deactivate your Fritz!Box-WLAN

The Fritz!Box-Binding already supports controlling the built-in WIFI/WLAN and DECT. Please see the Binding page.

How to display Google Maps in a sitemap from a Mqttitude Mqtt message

First, create a MQTT entry in your items file that subscribes to the Mqttitude push:

String Location_Dan_Phone {mqtt="<[home:owntracks/daniel/iphone5s:state:JS(mqttitude-coordinates.js)]"}

The transform is a javascript file in the configuration/Transform directory (mqttitude-coordinates.js). This file is very simple:

var location = eval('(' + input + ')');
result = location.lat + "," + location.lon;

The value of your item (Location_Dan_Phone) will be set to the result value.

Create a webpage that you will put in the webapps/static directory, call it map.html

<!DOCTYPE html>
<html>
  <head>
    <style>
      #map_canvas {
        width: 900px;
        height:500px;
      }
    </style>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
    <script src="//maps.googleapis.com/maps/api/js?sensor=false"></script>
    <script>
      $(function() {
	$.ajax({
		url: "/rest/items/Location_Dan_Phone?type=json",
		dataType: "json",
  		data: {
		},
  		success: function( data ) {
			 console.log(data);
			 var coords = data.state.split(',');
			 var latlng = new google.maps.LatLng(coords[0],coords[1]);
			 var map_canvas = document.getElementById('map_canvas');
		         var map_options = {
          			center: latlng,
          			zoom: 14,
          			mapTypeId: google.maps.MapTypeId.HYBRID
        		}
        		var map = new google.maps.Map(map_canvas, map_options)
			var marker = new google.maps.Marker({
				position: latlng,
    				map: map,
    				title:"Dan's Phone",
				image: "http://s1.hubimg.com/u/7148626_f520.jpg"
			});
      		}
  	  });
	});
    </script>
  </head>
  <body>
    <div id="map_canvas"></div>
  </body>
</html>

now reference the full URL to this page in a webview widget in your sitemap, something like

Webview  url="https://openhab.mydomain.com:8443/static/map.html"  height=12

Make sure you you have username and password authentication turned on!

How to use Yahoo weather images

This tip allows you to use Yahoo! weather images in your sitemap. See the Yahoo! Weather Developer page for more information.

First we need to download a current set of yahoo images to the runtime/webapps/images folder, there are 48 total. This command assumes you have imagemagick installed. This is included in most linux distros, on mac you can install it using brew like : brew install imagemagick.

for i in `seq 0 47`;do curl http://l.yimg.com/a/i/us/we/52/$i.gif | convert - yahoo_weather-$i.png ;done

Note that we prefix the images with yahoo_weather, this is important as openHAB will append a yahoo weather code later to choose the correct one.

Next add a xsl transform file to your configuration/Transform directory, name this yahoo_weather_code.xsl

<?xml version="1.0"?>
<xsl:stylesheet 
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0" version="1.0">
	<xsl:output indent="yes" method="xml" encoding="UTF-8" omit-xml-declaration="yes" />
	<xsl:template match="/">
		<!--<xsl:text>yahoo-weather-</xsl:text>-->
		<xsl:value-of select="//item/yweather:condition/@code" />
	</xsl:template>
</xsl:stylesheet>

This will return the Yahoo! weather code for a selected region.

We can map the weather code to a description so the item has both an image and text. Name this yahoo_weather_code.map in the Configuration/Transform directory.

0=tornado
1=tropical storm
2=hurricane
3=severe thunderstorms
4=thunderstorms
5=mixed rain and snow

41=heavy snow
42=scattered snow showers
43=heavy snow
44=partly cloudy
45=thundershowers
46=snow showers
47=isolated thundershowers

Add a Number item to a items file

Number YahooWeatherCode "Today is [MAP(yahoo_weather_code.map):%s]" (weather) { http="<[http://weather.yahooapis.com/forecastrss?w=2459115:3600000:XSLT(yahoo_weather_code.xsl)]"}

And a Text item to your sitemap

Text item=YahooWeatherCode icon="yahoo_weather"

How to wake up with Philips Hue

You want to make your morning light up with philips hue, the follow the steps

First you make a rule to wake up a certain time, for example 6:30 in the morning between Monday and Friday. This rule call the script dimmlight wich you can use later also in a other rule.

rule "Wakeup"

when 
	    Time cron "0 30 06 ? * MON-FRI "  
then


callScript("dimmlight")

end

Now you make the script dimmlight.script

var Number Dimmer

Dimmer=0


 
while(Dimmer<100 )


{
        Dimmer=Dimmer+5
        sendCommand(Light_LR_Living_Sofa_D,Dimmer)
        Thread::sleep(400)
        
}

Thread::sleep(400)

a higher value will dimm the light slower, a lower value will dimm the light faster

How to manage and sync configuration via subversion

In this guide subversion is used to both store your config and sync it between you local computer and the openhab server.

Setting up subversion

First setup a subversion server on your openhab server. You'll will find plenty of howtos how to do that. We asume that your repo is stored in /var/lib/svn/openhab and is running under the system user www-data

Install hook script

A hook script is used to apply all changes in the subversion repo to the actual openhab config. Create a hook-script /var/lib/svn/openhab/hooks/commit-hook with the following contents

#!/bin/sh
REPOS="$1"
REV="$2"
svn up /opt/openhab/configurations

The path in the last line has to match to your openhab installation

Import your config into subversion

Probably you already have an configuration. Import this into your subversion server. On Windows TortoiseSVN does a good job for that.

Checkout openhab config on server

You have to checkout the configuration into openhab once

svn co http://yourhost/svn/openhab /opt/openhab/configurations

Maybe you have to delete your existing configuration folder in /opt/openhab first

Setting up permissions

The tricky part is to setup the permissions right. I assume you subversion server runs with www-data and openhab with openhab system user. The problem is that www-data needs the permission to write to your openhab configuration.

chown -R openhab.www-data /opt/openhab/configuration find /opt/openhab/configuration -type d -exec chmod g+ws {} \;

How to switch LEDS on cubietruck

Items

/* LEDS */
Switch LED_Blue	{exec=">[ON:/bin/sh@@-c@@echo 1 | sudo tee /sys/class/leds/blue:ph21:led1/brightness] >[OFF:/bin/sh@@-c@@echo 0 | sudo tee /sys/class/leds/blue:ph21:led1/brightness]"}
Switch LED_Orange {exec=">[ON:/bin/sh@@-c@@echo 1 | sudo tee /sys/class/leds/orange:ph20:led2/brightness] >[OFF:/bin/sh@@-c@@echo 0 | sudo tee /sys/class/leds/orange:ph20:led2/brightness]"}
Switch LED_White {exec=">[ON:/bin/sh@@-c@@echo 1 | sudo tee /sys/class/leds/white:ph11:led3/brightness] >[OFF:/bin/sh@@-c@@echo 0 | sudo tee /sys/class/leds/white:ph11:led3/brightness]"}
Switch LED_Green {exec=">[ON:/bin/sh@@-c@@echo 1 | sudo tee /sys/class/leds/green:ph07:led4/brightness] >[OFF:/bin/sh@@-c@@echo 0 | sudo tee /sys/class/leds/green:ph07:led4/brightness]"}

Permissions

Create /etc/sudoers.d/leds

ALL ALL = (ALL) NOPASSWD: /usr/bin/tee /sys/class/leds/blue\:ph21\:led1/brightness
ALL ALL = (ALL) NOPASSWD: /usr/bin/tee /sys/class/leds/green\:ph07\:led4/brightness
ALL ALL = (ALL) NOPASSWD: /usr/bin/tee /sys/class/leds/white\:ph11\:led3/brightness
ALL ALL = (ALL) NOPASSWD: /usr/bin/tee /sys/class/leds/orange\:ph20\:led2/brightness

How to use a voice command from HABDroid

HABDroid uses a predefined string item to pass voice commands - the name of this item is "VoiceCommand". So all you have to do is to add such an item in your *.items file:

String VoiceCommand

And react on commands for this item in a rule:

 rule VoiceControl
 when
 	Item VoiceCommand received command
 then
 	val hue = switch(receivedCommand.toString.lowerCase) {
	 	case "blue"    : 240
	 	case "magenta" : 300
	 	case "green"   : 120
	 	case "yellow"  : 70
 	}
 	Light.sendCommand(hue + ",100,100")
 end

Add Humidex calculation for your Feels Like Temperature value

I think we can do the same with Heat index for US, but for the moment this is the european version, it works perfectly with Netatmo but it should be ok for any weather/climate technology.

The items file could look like this:

/*Humidex "Feels like" Temperature */
Number Humidex_Outdoor_Temperature "Feels like [%.1f °C]" <temp_windchill>	(Weather)

The rules file looks like this:

// Humidex Rule
rule "Humidex calculation"
when
  Item Netatmo_Outdoor_Temperature changed or
  Item Netatmo_Outdoor_Humidity changed or
  System started
then
  var Number T = Netatmo_Outdoor_Temperature.state as DecimalType
  var Number H = Netatmo_Outdoor_Humidity.state as DecimalType
  var Number x = 7.5 * T/(237.7 + T)
  var Number e = 6.112 * Math::pow(10, x.doubleValue) * H/100
  var Number humidex = T + (new Double(5) / new Double(9)) * (e - 10)
  postUpdate(Humidex_Outdoor_Temperature, humidex);
end

Aeon Zstick Setup in Linux

The Aeon Zstick is a serial USB device in Linux, but it does not use the generic usbserial device drivers.

Running lsusb you will find it is a CP210x device:

#lsusb
Bus 001 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device

To get it working you will need to be sure that you have P210x serial device drivers.

# dmesg | grep cp210x
cp210x: v0.08:Silicon Labs CP2101/CP2102 RS232 serial adaptor driver

If not you will need to find and install the package for your distro. Once that is done you should be able to verify your USB device in the dmesg logs:

Aug 16 15:59:59 (none) user.info kernel: USB Serial support registered for cp2101
Aug 16 15:59:59 (none) user.info kernel: cp2101 1-1:1.0: cp2101 converter detected
Aug 16 15:59:59 (none) user.info kernel: usb 1-1: reset full speed USB device using uhci_hcd and address 2
Aug 16 15:59:59 (none) user.info kernel: usb 1-1: cp2101 converter now attached to ttyUSB0
Aug 16 15:59:59 (none) user.info kernel: usbcore: registered new interface driver cp2101
Aug 16 15:59:59 (none) user.info kernel: cp210x: v0.08:Silicon Labs CP2101/CP2102 RS232 serial adaptor driver

Most full Linux distro's will have the CP210x module by default, but I am running SLiTaZ linux which is a very lo-ram slimmed down distro (runs in 30MB) so I provide these instructions for anyone else wondering why the device might not be working out of the box in their environment

How to use a serial port under linux

If you are usiung a usb-to-serial-adapter your serial-interface might be /dev/ttyUSB0.

Check the permissions of this device with

user@computer:~$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Aug 11 14:16 /dev/ttyUSB0

In order to access this device the user running openHAB needs to be in the group "dailout" and possibly the group "lock".

sudo adduser <user> dialout
sudo adduser <user> lock

Reboot your system.

Using the transceiver RFXtrx433E with Somfy RTS devices

The first thing you have to do is to pair the RFXtrx433E transceiver with your Somfy RTS devices (see http://rfxcom.com/Documents/RFXtrx%20User%20Guide.pdf for more details). If you pair for example a roller shutter with the ID 1.01.01.1, then the binding should look like:

Rollershutter rs_1 "Yoda" <rollershutter> (Rollershutters) {rfxcom=">1.01.01.1:RFY.RFY:Shutter"}

Talking to a Raspberry ZWAY device with push updates

(ZWAY version 2.0+ only)

This works for any device on a ZWAY server, in this example we will bind the Alarm V1 event data for a lock to a OpenHAB item. First create an Item to represent the alarm state, this will use the http binding to get it's initial state and periodically update (every hour) its self in case we loose a message.

Number ZWAY_LOCK_ALARM "Last Status [MAP(lock.map):%d]" {http="<[http://raspberry2:8083/ZWaveAPI/Run/devices%%5B2%%5D.Alarm.data.V1event.alarmType.value:3600000:REGEX((\\d*?))]"}

The URL we are hitting is raspberry2:8083/ZWaveAPI/Run/devices[2].Alarm.data.V1event.alarmType.value but in order to pass the '[' and ']' characters we need to escape them with '%%5B' and '%%5D'.

Next we want to be updated when anything changes on the ZWAY device. We are going to load a javascript file that will bind to our device. In the ZWAY automation UI, make sure you have the Javascript file load module enabled. Place the following javascript file in "/opt/z-way-server/automation/storage/':

this.registerOhBinding = function(zwayName) {
  debugPrint("OH Binding called with name: " + zwayName);

  if (zwayName != "zway") return; // you want to bind to default zway instance

  debugPrint("OH Binding enabled!");

  var devices = global.ZWave["zway"].zway.devices;

  devices[2].Alarm.data.V1event.alarmType.bind(function(){
    debugPrint("Alarm.data.V1event.alarmType changed! " + this.value);
    global.http.request({
      method: 'PUT',
      url: "http://oh.yourdomain.com:8080/rest/items/ZWAY_LOCK_ALARM/state",
      data:this.value + "",
      headers    : { "Content-Type": "text/plain" }
    });
  });
};

debugPrint("Trying to bind OH");
// process all active bindings
if (global.ZWave) {
  global.ZWave().forEach(this.registerOhBinding);
}
// and listen for future ones
global.controller.on("ZWave.register", this.registerOhBinding);

Replace the URL in the file to match your OpenHAB instance and item name. In the ZWAY Javascript File load module enter 'storage/zway-oh.js' as the file (or whatever you named it). This code will send a HTTP post to the Item whenever the alarm state changes.

How to use the LIFX beta API via executeCommandLine and curl

To control the bulbs via this API you need to send HTTP requests (GET, POST, PUT). For security reasons you need a authentication token to access your bulbs. https://github.com/chendo/lifx-http/issues/27#issuecomment-72760322

Once you got the token, you can play around with the API web interface at https://api.lifx.com/

Unfortunately the HTTP binding does not support sending http headers.

The only way to send the request is using the executeCommandLine command and the unix program curl.

A working example looks like this:

var String lifxurl   = "https://api.lifx.com:443/v1beta1"
var String lifxtoken = "c7a3****a98c"       // insert your token here

executeCommandLine("curl@@-k@@-H@@Authorization: Bearer " + lifxtoken + "@@-XPOST@@" + lifxurl + "/lights/all/effects/pulse.json?color=green")

// if you want to change the color or state you need to replace "XPOST" with "XPUT"
// according to the documentation on https://api.lifx.com/
executeCommandLine("curl@@-k@@-H@@Authorization: Bearer " + lifxtoken + "@@-XPUT@@" + lifxurl + "/lights/all/color.json?color=hsb:45,1,0.6")

Notice the "@@". This is neccessary, because the executeCommandLine does not support using quotationmarks. To send the http header as one string, all other spaces need to be replaces by the delimiter "@@".

You may experience some seconds delay, because this is not the best way to implement the LIFX bulbs in openHAB. There is a dedicated lifx binding for openhab2 wich works without internet (cloud) connection.

How to turn ON and OFF a Philips Hue with HomeMatic pushbutton

You want to turn ON and OFF a Philips Hue with a physical pushbutton (e.g. HomeMatic HM-PBI-4-FM). You need to define the states of the HomeMatic pushbutton as items in the .items file:

// Unreachable:
Switch HM_pushbutton_Unreach "Signal Strength [MAP(signal_status.map):%s]" <signal> (g_HM_Signal) {homematic="address=LEQ0012345, channel=0, parameter=UNREACH"}
//LowBattery:
Switch HM_pushbutton_LowBattery "Battery Status [MAP(batterie_status.map):%s]" <signal> (g_HM_Signal) {homematic="address=LEQ0012345, channel=0, parameter=LOWBAT"}
//Channel 1:
Switch HM_pushbutton_Channel_1 "Pushbutton 1" {homematic="address=LEQ0012345, channel=1, parameter=PRESS_SHORT"}
//Channel 1 (Press long):
Switch HM_pushbutton_Channel_1_long "Pushbutton 1 (long)" {homematic="address=LEQ0012345, channel=1, parameter=PRESS_LONG"}

Copy these switches for channel 2, 3, and 4 of the HomeMatic pushbutton and add your Hue bulbs like this:

Switch Toggle_1   "Hue 1"   (Switching) {hue="1"}

See also this Link for the Hue Color and Dimmer item. To receive the signals of the pushbutton you have to set the mode of transmission within the CCU/CCU2 to be standard. (enabled security will not work. For more information see here)

After this preparation only the rule is missing. Copy the following into your .rules file:

var Number Toggle_1_on = 0

rule " Channel 1 press short"
when
	Item HM_pushbutton_Channel_1 changed to ON
then
	if (Toggle_1_on == 0){
	sendCommand(Toggle_1, ON)
	Toggle_1_on = 1}
else{
	sendCommand(Toggle_1, OFF)
	Toggle_1_on = 0}
end

Pressing the physical pushbutton connected to channel 1 of the HomeMatic HM-PBI-4-FM will now toggle the Philips Hue (Toggle_1) on and off.

How to create a simple Remote for controlling a Dune HD Player with Http and Denon Bindings

A Dune HD multimedia player (http://dune-hd.com/eng) is easily manageable via Http Binding. The golden rule is to remember that any 4-byte NEC IR code supported by Dune (see http://dune-hd.com/support/rc) needs to be written in the opposite order (e.g. RC button "1" = 00 BF 0B F4 => F40BBF00).

Here a very simple Remote control with some basic commands:

/* Dune items */
/* Living */
Switch Dune_Living		"power"     (Dune, Persistence)
Number Dune_RC1_Living  "" 			(Dune)					{autoupdate="false"}
Number Dune_RC2_Living  "" 			(Dune)					{autoupdate="false"}
Number Dune_RC3_Living  "" 			(Dune)					{autoupdate="false"}

rule "Dune Living Room Remote Control line 1"
        when 
                Item Dune_RC1_Living received command 
        then 
                switch(receivedCommand)
                
                {
                    case 1 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=EA15BF00") 

                    case 2 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=E916BF00") 

                    case 3 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=E817BF00") 

                    case 4 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=E718BF00")

                    case 5 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=EB14BF00")
		}
end

rule "Dune Living Room Remote Control line 2"
        when 
                Item Dune_RC2_Living received command 
        then 
                switch(receivedCommand)
                
                {
                    case 1 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=B748BF00") 

                    case 2 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=E11EBF00") 

                    case 3 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=E619BF00") 

                    case 4 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=B649BF00")

                    case 5 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=E21DBF00")
		}
end

rule "Dune Living Room Remote Control line 3"
        when 
                Item Dune_RC3_Living received command 
        then 
                switch(receivedCommand)
    
                {
                    case 1 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=BB44BF00") 

                    case 2 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=AB54BF00") 

                    case 3 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=AF50BF00") 

                    case 4 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=F807BF00")

                    case 5 : sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=FB04BF00")
		}
end

And here an example how to integrate with your AVR. In this case, a Denon AVR 3311: e.g. when I click ON I need to switch on the AVR, set the channel to BD (HDMI connected to Dune HD Player) and switch on the Dune Player:

rule "Dune Living"
when
	Item Dune_Living received command
then
	if(receivedCommand==ON) {
		// switch on AVR, set input to BD, switch on Dune HD
		sendCommand(DenonPower, ON)
		sendCommand(DenonInputBluray, ON)
		sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=A05FBF00")
	} else if(receivedCommand==OFF) {
		// turn off Dune HD and AVR
		sendHttpGetRequest("http://<ip_address>/cgi-bin/do?cmd=ir_code&ir_code=A15EBF00")
		sendCommand(DenonPower, OFF)
	}
end

Then, a very simple sitemap:

Text label="Dune HD" icon="dune_hd3"{
	Switch item=Dune_Living icon="control_standby"
	Slider item=DenonVolume icon="audio_audio"
	Text item=DenonVolumedB
	Switch item=DenonMute icon="audio_volume_mute"
	Switch item=Dune_RC1_Living mappings=[1=" Up ", 2=Down, 3=Left, 4=Right, 5=Select]
	Switch item=Dune_RC2_Living mappings=[1=" Play ", 2=Pause, 3=Stop, 4=Prev, 5=Next]
	Switch item=Dune_RC3_Living mappings=[1=" Audio", 2=Subtitle, 3=Info, 4="Pop Up", 5=" Return "]
}

Last few notes for DenonVolume, how to see dB and how to start with a predefined level (in this case, 40 dB):

Dimmer DenonVolume          "volume [%.1f]"     (Denon)	{denon="avr3311#MV"}
Number DenonVolumedB		"[%.1f dB]"	(Denon)

rule "DENON DB to Volume"
when
	Item DenonPower changed from OFF to ON
then
/* 	var Number volume = (DenonVolumedB.state as DecimalType)+80 */
	sendCommand(DenonVolume, 40)
	logInfo("Rules", "DENON Volume initialized");
end

rule "DENON Volume to DB"
when
	Item DenonVolume changed
then
	if (DenonVolume.state == Undefined || DenonVolume.state == Uninitialized) 
		return false
	else {
		var Number volumedB = (DenonVolume.state as DecimalType)-80
		postUpdate(DenonVolumedB, volumedB)
	}
end
