Loxone Lightcontrol v2 to HA to control Zigbee RGBW Lamps

Third party integrations
1

Hello everyone,

I’m new to the forum and also not very experienced with Home Assistant yet. I do have a basic understanding of Loxone.

Could someone please help me? I can’t seem to get one specific setup working.

My goal is to control Zigbee RGBW lamps via PYLoxone and the Loxone Light Controller block.
The visualization is done in Loxone, while the logic/intelligence runs in Home Assistant.

I have integrated the lamps into Home Assistant using Zigbee2MQTT, and they work very well within Home Assistant itself.

In Loxone, I created the Light Controller block (although I’m not entirely sure if it is configured correctly).
For testing, I created a simple automation in Home Assistant using the editor (initially only switching on and setting colors).

I am able to switch the light on, but I cannot dim it or control the colors from Loxone.

Both systems are running the latest versions:

  • Latest Loxone software
  • Latest Home Assistant version

I will attach some screenshots from Loxone and Home Assistant. Sorry but as new user I am allowed only to add on screenshot.

I would really appreciate any help and the opportunity to learn more about this setup.

** I’ve solved the issue!

Key points:

  • The Light Controller V2 must be connected to a Virtual Output
    (important: set the output to (v) nothing).
  • No address is required in the basic configuration. This does not matter because PYLoxone automatically picks up the data.
  • The light output must be set to RGB. Even though I am using RGBW lamps (IKEA), PYLoxone correctly handles them as lights.
  • Scenes:
    • Color scene: in my case, magenta with a defined dim level
    • Maximum light output (“Full brightness”): any color temperature with a defined dim level
  • All settings can be changed via the Loxone visualization.

Finally, create an automation in Home Assistant with a trigger from the Loxone Light Controller, controlling the IKEA lamp integrated via Zigbee2MQTT.**
