+# EspMilightHub Binding
+
+This binding allows an open source esp8266 based bridge to automatically find and add Milight globes.
+The hubs can be built from 2 ready made boards and only need connecting with 7 wires. 
+They can be very easy to build with no soldering needed. 
+
+Advantages to using this DIY bridge over the OEM bridge:
+
++ Almost unlimited groups to give individual control over an entire house of Milight globes without needing multiple bridges.
++ If using the Milight remotes to control the globes, this binding can update the openHAB controls the moment a key is pressed on the physical remotes.
++ Supports auto discovery.
+
+## Setup the hardware
+
+In depth details on how to build and what the bridge is can be found here: <http://blog.christophermullins.com/2017/02/11/milight-wifi-gateway-emulator-on-an-esp8266>
+
+A quick overview of the steps to get the hardware going are:
+
++ Connect a nodemcu/D1 mini/esp8266 to your computer via a USB cable.
++ Download the latest BIN file from here <https://github.com/sidoh/esp8266_milight_hub/releases>
++ Download esp8266flasher if you are on windows <https://github.com/nodemcu/nodemcu-flasher>
++ Check the blog above on more info for Mac or Linux.
++ Open the flasher tool and make sure the flash size is 4mb or whatever your esp8266 board has.
++ Flash the bin and press the reset button on the board when it completes.
++ Connect to the wifi access point of the esp directly with your phone/tablet and setup wifi details.
++ Login by using the IP address of the esp8266 in a web browser and the control panel will show up.
++ Connect 7 wires between the two ready made PCBs as shown in the blog.
++ Setup a MQTT broker as this method uses the faster and lightweight MQTT protocol and not UDP.
+
+## Setup the Firmware
+
+Enter the control panel for the ESP8266 by using any browser and enter the IP address. 
+The following options need to be changed in the firmware for the binding to work.
+Click on SETTINGS>MQTT>:
+
+**mqtt_topic_pattern:**
+`milight/commands/:device_id/:device_type/:group_id`
+
+**mqtt_update_topic_pattern:**
+Leave this blank.
+
+**mqtt_state_topic_pattern:**
+`milight/states/:device_id/:device_type/:group_id`
+
+**group_state_fields:** 
+IMPORTANT: Make sure only the following are ticked:
+
++ state
++ level
++ hue
++ saturation
++ mode
++ color_temp
++ bulb_mode
+
+Fill in the MQTT broker fields with the correct details so the hub can connect and then click **save**.
+Now when you use any Milight remote control, you will see MQTT topics being created that should include `level` and `hsb` in the messages.
+If you see `brightness` and not `level`, then go back and follow the above setup steps.
+
+You can use this Linux command to watch all MQTT topics from Milight:
+
+```
+mosquitto_sub -u usernamehere -P passwordhere -p 1883 -v -t 'milight/#'
+```
+
+You can also use the mosquitto_pub command to send your own commands and watch the bulbs respond all without the binding being setup.
+Everything this binding does goes in and out via MQTT and can be watched with the above command.
+Once you have setup and test the hub you can move onto using the binding.
+
+## Supported Things
+
+This binding is best thought of as a remote control emulator, so the things are really the type of remote that you own and not the globes.
+The Milight protocol is 1 way only so there is no way to find actual globes.
+
+| Thing Type ID | Description |
+|-|-|
+| `rgb_cct` | Remote that has 4 channels and controls globes with full colour, and both cool and warm whites. |
+| `fut089` | Remote is the newer 8 channel type called FUT089 and your globes are the rgb_cct. |
+| `cct` | Remote is 4 channels and the globes have no colours with only cool and warm white controls. |
+| `fut091` | Remote is the newer 8 group model called a fut091 and your globes are cct. |
+| `rgbw` | Remote is 4 channels and the globes have RGB and a fixed white. |
+| `rgb` | Remote is 4 channels and the globes have full RGB with no white. |
+
+## Discovery
+
+First install the MQTT binding and setup a `broker` thing and make sure it is ONLINE, as this binding uses the MQTT binding to talk to your broker and hence that binding must be setup first.
+Next, move a control on either a physical remote, or used a virtual control inside the esp8266 control panel web page which cause a MQTT message to be sent.
+This binding should then detect the new device the moment the control is moved and a new entry should appear in your INBOX.
+
+To remove a saved state from your MQTT broker that causes an entry in your INBOX you can use this command or use the ignore feature of openHAB.
+
+```
+mosquitto_pub -u username -P password -p 1883 -t 'milight/states/0x0/rgb_cct/1' -n -r
+```
+
+## Thing Configuration
+
+| Parameter | Description | Required | Default |
+|-|-|-|-|
+| `whiteHue` | When both the `whiteHue` and `whiteSat` values are seen by the binding it will trigger the white LEDS. Set to -1 to disable, 0 for Alexa, or 35 for Google Home. | Y | 35 |
+| `whiteSat` | When both the whiteHue and whiteSat values are seen by the binding it will trigger the white LEDS. Set to -1 to disable, 100 for Alexa or 32 for Google Home. | Y | 32 |
+| `favouriteWhite` | When one of the shortcuts triggers white mode, use this for the colour white instead of the default colour. | Y |200 |
+| `dimmedCT` | Traditional globes grow warmer the more they are dimmed. Set this to 370, or leave blank to disable. | N | blank |
+| `oneTriggersNightMode` | Night mode is a much lower level of light and this feature allows it to be auto selected when your fader/slider moves to 1%. NOTE: Night mode by design locks out some controls of a physical remote, so this feature is disabled by default. | Y | false |
+| `powerFailsToMinimum` | If lights loose power from the power switch OR a power outage, they will default to using the lowest brightness if the light was turned off before the power failure occurred. | Y | true |
+| `whiteThreshold` | RGBW globes do not respond to saturation changes, so this feature allows you to specify a number that if the saturation drops below, it will trigger the white mode. -1 will disable this feature. | Y | 12 |
+
+## Channels
+
+| Channel | Type | Description |
+|-|-|-|
+| `level` | Dimmer | Level changes the brightness of the globe. |
+| `colourTemperature` | Dimmer | Change from cool to warm white with this control. |
+| `colour` | Color | Allows you to change the colour, brightness and saturation of the globe. |
+| `discoMode` | String | Switch to a Disco mode directly from a drop down list. |
+| `bulbMode` | String (read only) | Displays the mode the bulb is currently in so that rules can determine if the globe is white, a color, disco modes or night mode are selected. |
+| `command` | String | Sends the raw commands that the buttons on a remote send. |
+
+## Note Regarding Transmission Delays
+
+If you have lots of globes and openHAB turns them all on, you may notice a delay that causes the globes to turn on one by one and the delay can add up when a lot of globes are installed in your house.
+This is caused by the time it takes to transmit the desired setting to the globe multiplied by how many times the hub repeats transmitting the setting.
+Since it takes around 2.8ms for a setting to be transmitted, if the firmware is set to repeat the packets 50 times it would then take 2.8*50 = 140ms before the next globe starts to have its new state transmitted by the hub.
+You can reduce the packet repeats to speed up the response of this binding and the hub by tweaking a few settings.
+
+Settings can be found on the radio tab in the esp control panel using your browser.
+Suggested settings are as follows:
+
++ Packet repeats = 12 (if you only turn 1 globe on or off it uses this value)
++ Packet repeat throttle threshold = 200
++ Packet repeat throttle sensitivity = 0
++ Packet repeat minimum = 8 (When turning multiple globes on and off it will use this value as it throttles the repeats back to reduce latency/delay between each globe)
+
+## Important for Textual Configuration
+
+This binding requires things to have a specific format for the unique ID, the auto discovery does this for you.
+
+If doing textual configuration you need to add the Device ID and Group ID together to create the things unique ID.
+The DeviceID is different for each remote.
+The GroupID can be 0 (all channels on the remote), or 1 to 8 for each of the individual channels on the remote).
+If you do not understand this please use auto discovery to do it for you. 
+
+The formula is
+DeviceID + GroupID = ThingUID
+
+For example:
+
+| Device ID | Group ID |ThingUID  | 
+|-----------|----------|----------|
+| 0xE6C     | 4        | 0xE6C4   | 
+| 0xB4CA    | 4        | 0xB4CA4  | 
+| 0xB4CA    | 8        | 0xB4CA8  |
+| 0xB4CA    | 0        | 0xB4CA0  |
+
+## Full Example
+
+To use these examples for textual configuration, you must already have a configured a MQTT `broker` thing and know its unique ID.
+This UID will be used in the things file and will replace the text `myBroker`.
+The first line in the things file will create a `broker` thing and this can be removed if you have already setup a broker in another file or via the UI already.
