Hi everybody,
First, thanks a lot to all developers, members, in fact all the community who gave me the ability to control my first RGB color LEDs without original commercial bridge. I’m a newcomer (about 1 month), and I’m really impressed and excited by your OpenHab Project!!!
Because i had some problems to render “true” colors with “hue bridge” or “deconz bridge”, and thinking mqtt is more “brut” and will let me have more integration possibilities for futures devices, I choosed this way, and i am thinking today it was not wrong… for RGB only 
:
nobody knows what future will bring
So after burning my head reading forum topics, documentations and what else?, I decided to subscribe your community, to continue to progress and understand, maybe help someone 
, hoping some help or even just little directions during i digest all, and savor some won battles, before coming back to war!

Sniffing mqtt traffic :
$ mosquitto_sub -h '192.168.1.24' -p 1883 -u openhabian -P 'Rpi01OHMqtt!44?' -v -t 'zigbee2mqtt/#'
zigbee2mqtt/E27/set {"color":{"rgb":"250,250,250"}}
zigbee2mqtt/E27 {"brightness":96.52,"color":{"x":0.3227,"y":0.329},"color_temp":165,"linkquality":208,"state":"ON"}
Note :
I choose “JSON output” (i think the default in fact), because I’m not able to set “color-x”/“color-y”, the separated “attribute output”. Maybe using both should solved some problems.
What is WORKING !
- Bridge and binding
- Switchs ON/OFF
- Brightness control
- Color control, through RGB mode
- Reading linkquality value
What I’m looking for ?
- Where an how writing “availability topic” in the thing file ? (i got it when i create thing through GUI)
- Why brightness output value is percent value ? Is “JSONPATH:$.brightness” wrong ? Or is it just the item configuration ?
And color output is wrong too! (of course if reading X,Y value)
- I defined i my model a scale 0-100 to brightness control, that’s running, but in the “auto-generated” card , it still appears as 0-255. Where am i wrong ?
- Why “sended” max color control value (“r”, “g” or “b”) is 250 ? (maybe have to try “%d,%d,%d”) (cf “sniffing traffic”)
- Can’t switch in “white color temperature” mode. (maybe have to set “colorMode”=“CT” if possible)
Hoping I respected Guidelines,
Thanks for reading, and future help,
And good continuation!
