Alexa control

[csph]

Hi, I dont know if it is an issue or if I do a mistake.

I just set up my ESP8266 with your basic HTTP OTA updater installing the wled05dev_1801102_RGB_ESP8266.bin, wich was quite easy. Thumbs up!

After this I typed in my wifi data and everything seems to work. (I haven't connected my LED's yet).

But when I search for new devices with my echo dot, it cant find the esp8266.
The option "Emulate Alexa device" is on.
Do I have to activate a skill or so?

Hi @Master-P96 ,

thank you for trying out my software! 😄 Awesome you had no troubles with the installation!

The Alexa integration works without a skill. Please check first if the settings field "Alexa Invocation Name" is filled with the device name you want it to have. Please reset the ESP once, because Alexa Emulation will only work after a reboot. Also make sure your router has UPnP enabled or try searching via the Alexa app or multiple times. This may help :)

If that doesn't help, may I ask what ESP8266 board you are using (ESP-01, wemos d1, Nodemcu, ...)? The binaries should work for all ESPs but we could make sure that is not the problem by compiling a binary just for your board.

Hope I'm able to help!

Thank you for your fast reply :)
I just connected my LED's and it works fantastic! Very nice work.

But back to my issue:
Alexa Invocation Name is filled (I also changed the name several times).
Resetting and multiple times of searching for a device did not solve the problem.
I have a FritzBox 7580 with UPnP enabled.
Does an update with the integrated updatefunction (upload the bin) count as a "fresh" installation?

I use an NodeMCU Lolin V3.

Thanks for your help!

I'm so happy you like my work :)

Here is a recent binary compiled for your board: https://drive.google.com/file/d/1Hcw5_LpsTbWiLaXj9gFqo1kOPUwi2ZOS/view
Since everything but Alexa control seems to work fine for you though I don't know if this will solve the issue. I have also turned on serial debug for this build. If you open the Arduino IDE serial monitor and ask Alexa to discover devices, it should normally flood it with debug data like "AlexaApiCall".

When I tried it myself again today, Alexa said she found no new devices, but voice control worked reliably anyways. To be honest, Alexa is a bit weird sometimes. It also occasionally happens that she says: "Device doesn't react. Please check power and network", but the light turns on anyways. One time though, Alexa was unable to control any device (even the ones already discovered) until I power cycled the Echo itself, then it was flawless. Strange stuff.

If that doesn't work, you could also try and use the binary "wled04_1712122_RGB.bin". It is an older version, but it uses a different way to communicate with Alexa (doesn't support dimming, just on and off, but it just might work for you)

A "fresh install" is unlikely to solve anything. Just in case you'd like to try it, the software preserves your settings (Wifi, led, Alexa...) in file system memory, which means it will "survive" software updates. If you use the "ip/update" page to do a .bin update, to reset the settings, you'll also need to scroll way down in the settings page and tick the "Factory Reset" checkbox, then reboot. It will delete all settings, including your WiFi password and everything you had changed.

I really hope for you that we can fix the issue! (since I myself have ~10 ESPs running the software and pretty much only control them via Alexa, since it's so much quicker than opening the browser) Please tell me if any of my suggestions worked :)

By the way, in 1-2 weeks I'll upload a large update that will improve the looks of the web page (themes) and add a couple of new effects and features! Stay tuned for that!

The version you send unfortunatly doesn't fix it, also there is no reaction in the Monitor when searching with the echo.

I installed the 0.4 and the echo found the device instantly!
You have an idea what might be the problem?

But I'am happy for now, voice control is so comfortable ;)

Can't wait for the update!

[Aircoookie]

Ok, at least the 0.4 version seems to work :)

To be honest I have no idea what the problem may be... :/
Could be WLED, could be the underlying UDP or Philips hue protocol, could even be your echo...
If you want to help me find the state at which the discovery fails, run this Arduino sketch:
https://drive.google.com/open?id=1d01gRgzTIyjCRMyLydFp0IwuMjQU1YuK
It is the minimal code to get Alexa and ESP8266 connected and outputs all relevant debug data to serial.
You'd just need to put your WiFi in the strings at the top of the file, run it and then send me the entire serial output. It will also not delete your WLED settings ;)

Ah, one last question: what is the language and country you use your Echo in? May make a difference...

Thank you for your help! I hope that I can get the latest version working for you ASAP :)

Okay here is the output:

While the output was created I made an attempt to find new devices with the echo.
The language is german.

Hope it helps you!

[Aircoookie]

Ok, an der Sprache liegt es schonmal nicht :) Danke für die Hilfe!

From what you posted it seems like your Echo doesn't send the required UDP device discovery requests. There are none in the log at least...

I did some more testings and it seems like Echo dot searches for urn:schemas-upnp-org:device:basic:1 devices while the Echo 2/Plus searches for upnp:rootdevice instead. This is very strange, but here is a new binary (which accepts both requests) that may or may not work for you:
https://drive.google.com/open?id=1aN8bO10qiLvRbGyXYBaWixOAP2nyQ46-
Please unplug and restart your Echo once again before trying it out, and don't forget to try it via the app also.

This binary should theoretically work for you if WLED 0.4 does, but at this point I can't guarantee for anything... If it doesn't, I have no idea how to fix it since the echo does not seem to send the discovery requests it is supposed to. I really wish for you that it will work though! :)

[csph]

Well I think you fixed it!
With the new version the echo found the ESP without problems :)

Nice work mate, and thanks for the great support!
I really looking forward to the upcoming development of this project 👍

[Aircoookie]

That's perfect news! I was afraid it was not fixable, but it worked out and I'll definiately include the change in the next update :)

[d-works42]

Hi, this is an awesome project idea and I hope I´ll be able to get it working.
I basically have the same problem like Master-P96 while using a Adafruit huzzah and Echo Dot. Sadly i´m to stupid to get your custom binary uploaded so far... Any possibility to provide the customizes ino file?

Thank you so much for all the work you put into this!

[Aircoookie]

Hi @wcbuerste ,

I'm very happy that you like my project, really appreciate it :)

Sadly I can't offer the updated ino files yet, because I'm currently working on a big update/restructuring, which means that the sketch does not compile/work at the moment.

However, you can easily fix the problem with Alexa yourself 👍 ! Just go to the sketch tab "wled12_alexa.ino" in the top of the Arduino IDE.
Then, in that file, just replace line 37:
This:
if(request.indexOf("upnp:rootdevice") > 0) {
needs to be replaced by:
if(request.indexOf("upnp:rootdevice") > 0 || request.indexOf("device:basic:1") > 0) {

That's all there is to it. Hope this will fix the problem for you like it did for Master-P96!

I will work hard to get the new version including the fix out as soon as possible :)

Have a nice weekend! :)

[d-works42]

Hi, thank you for the fast reply. This worked like a charm, could instantly connect in the Alexa app! =)
Having some effects with a brightness that gets reseted, but will investigate when I have more time.

[Aircoookie]

Hi @Ae3NerdGod , I'm afraid to tell you that WLED's Alexa support (based on Espalexa) doesn't work without a physical Echo device unfortunately. The other devices you can control probably use cloud APIs (as in you have to activate a skill and register with the light manufacturer). WLED uses the local Philips hue API, which is only supported by Echo Speakers at the moment, not by the apps themselves.

I hope that you'll have fun with WLED despite this issue and maybe we can find a solution at some point :)
