Loxberry MQTT to IKEA Tradfri and bonan/tradfri-mqtt

[Gast]

Hello there,

Im struck with my IKEA Tradfri Gateway

I have no problem controling ON/OFF / DIM from Loxone to whatever Tradfri device, but when it comes to RGB/CCT or just CCT im kindda lost, I guess I need to output Lumitech, like I do with my HUE Bridge Script, wich have been running for years,,, but converting from Loxone lightning to my Loxberry and from there to my MQTT broker, its for me a long way?

Hope someone have a suggestion, in this matter, I see theres some MQTT plugins inside Loxberry, but I have no idea how to combine them with my use?

Hey Dexter, did you get to solve your problem? I am also struggling to find an example that works and is easily scalable to multiple Bulbs

Hey loxClemo,
I may not directly help you as I'am using the IKEA Tradfri gateway with Node-RED instead of MQTT, as explained here https://loxwiki.atlassian.net/wiki/spaces/LOX/pages/1650393310/IKEA+Tradfri+Ger+te+mit+Tradfri+Gateway+in+Loxone+ einbinden

Well, it's German, but Google translate might be sufficient to understand the content and maybe you get a hint. I've used the type Lumitech as well and it was quite difficult to allow a conversion in BOTH directions, so that the IKEA buttons and remote controls are working as well as input via Loxone. One of the problems is the different scale 0-100% in Tradfri vs. 0-255 in Loxone, another is the fact that Loxone does not have a master on/off switch for a bulb that is dimmable, but only uses brightness, so brightness=0 is sufficient to turn a bulb off and brightness>0 is an implicit on. IKEA bulbs however do need an explicit on/off, so you have to add these commands (e.g. RGB, dimmable and white spectrum).

Now everything is working quite well in my installation. There is one "bug" that I was not able to solve: if you want to set brightness and color at the same time, then transitionTime needs to be set to 0, otherwise it is not working. I consider this a bug, but the IKEA app does not support moodes aka scenes, so it only occurs on input via Loxone and I don't know any official way to report this problem.
