WLED and Loxone

[Vidor Lakatos]

Hi All,

Is anyone using WLED with Loxone ? 

I think that it should be possible, but the documentation for the MQTT is very poor for my understanding. 
Also the API is pointing to a JSON way, which I'm not familiar with. 

Anyone with experience or config file perhaps as an example ? 

I'm been using WLED with a esp32 for weeks and looks very promising. I think that we could use it a lot within Loxone. 

Thank you.

I find some useful info on a german forum, but they mention a special ESP32 which works together with Loxone. https://shop.codm.de/automation/pixel/30/wlan-pixel-controller-wled 

There is also a mention on the WLED homepage that 

But still so far I could not get it working :(

There was some discussion of it a couple years ago:

Would be interesting to hear any updates on how people are integrating it

I have used something called Pixelblaze , you will also need a RPi running Firestorm. This acts as a gateway between the Pixelblaze and Loxone.  Then using HTTP you send commands to the Firestorm program which in turn controls the Pixelblaze.

I have several WLED lights running and they work without any issue, out of the box. You can control them right from Loxone.

I even have a WLED GU10 RGB led lamp that works with it. No issues at all for a decent price: https://www.athom.tech/blank-1/wled-gu10-rgbcw

I'm not at home now, so I can't share the Loxone integration, but will do this weekend.

As promised, here is how I set up WLED for Loxone:

You don't need a special version of WLED anymore: All recent versions have Loxone support build in. 

That's why you can even buy WLED bulbs and use them without modifications as an RGB light in any Loxone Light controller. It just works like any other RGB light. 

Of course, Loxone has no way to control each pixel of your RGB LED strip separately. Although there are workarounds to do so, this is not explained below. I only use them as single RGB light for the whole LED strip or bulb.

Here's how:

Step 1 - Hardware

Buy a WLED strip or bulb, or build one yourself with a ESP32 or ESP8266. 

WLED is easy to install on your DIY project with their web installer. 

I have done both ways and they all work fine and stable if you have decent wifi.

Step 2 - Setup WLED software

Find your WLED light using their mobile app: It searches for all WLED devices on your wifi. 

Set up your device in the app (LED type, nr of LEDs on the strip, ...)

Here you can also see the IP address of your device. Make sure to make this ip static on your router or give it a network name (SSID). You will need this IP or name later in Loxone. I always used the IP, so not sure if the SSID works evenly good.

Step 3 - Setup in Loxone

In Config:

a - Add a Virtual Output: The adress is /dev/udp/<your device ip>/21324

b - Add a command to your Virtual output:

Command for ON and OFF should be set like below. 

ON: LX=<v>&FX=0&T=1

OFF: LX=0&FX=0&T=0

See also the explanation at https://kno.wled.ge/interfaces/http-api/#loxone-commands

The LX=<v> part makes sure that the Loxone RGB value is send to WLED.

c - Drag your command to a Light Controller and choose type RGB:

That's it. You can now setup and control your WLED light like any other RGB light in Loxone ;-)

Good luck with your setup!

Gert,

Thank you very much ! 

I have all the necceseray HW and I will probably do it tonight ! 

I will keep you all posted with the results. 

Thx once again !

Hi Gert,

Been following your instructions and I'm able to turn on the light, but it won't change colour. This is the UDP message that Loxone is sending to the WLed controller.

I also see that something has changed in the Loxone config since the latest version. The command for off is no longer available in the virtual output if you uncheck the digital IO checkbox. 

Any idea's?

Thanks,

Hi,

Everything is still working as expected here, also with the latest version of Config.

Some settings you might check:

• In the Lighting Controller, in the "Light Circuits" tab, did you use "RGB" as Type for your WLED device?
• Did you use a Virtual Output, and NOT Virtual Text Output?
• Do NOT check "Use as Digital Output". You are right that you don't have an option for the "Off" section then, but that is not required because Loxone will use black as color for off, resulting in no light. In the WLED interface, however, you will see that the light is indeed not turned off, but that is as expected. I don't think this will result in more power consumption when the lights are off. 

I hope this helps!

Hi Gert,

Checked the Loxone light controller and it is set to RGB as you can see. I've also added a screenshot of the virtual output settings. What WLED version are you running? Mine is on 0.14.

Thanks,

One has 0.13.0-b6 and another has 0.14.0. Both are working fine.

Did you change the correction? These at should be on the default values. 

Here is my UDP log:

But looking at your logs, these looks very similar as mine ...

So no clue what's going wrong ...

To test if the WLED commands are working, you can use the WLED REST API  in your browser:

eg: To send the 2nd command in my list above,  from within a browser:

http://192.168.68.160/win&LX=27040071&FX=0&T=1

Of course, you have to adapt the IP address with yours.

Please let me know if this works, using different values for LX.
Setting LX to 0 should turn the lights to black, like in my last command.

Gert

Thanks for the quick reply. Just tested the http commands through the browser. I do get a response, the light turns on and off if I change the T command, the effects change when I send the FX command, but the colours just don't seem to change. If I send a blue command to the light I get a response with the current colour for example.

Ok, so it has nothing to do with Loxone.
In the WLED docs of the API you can find out more about the LX command. It is not simply RRRGGGBBB but a Loxone-format.

My example should give an orange-like color.

Just flashed the latest version of WLed to my Dig2Go and now it seems to work. Will need to dig a little deeper into finding the issue...
