Node-red with Müller-Licht tink (ZBT-ExtendedColor)

Hi!

I am trying to build some CO2 warning lamp for my son with homee, node-red and the Conbee USB stick.

I am able to control the lamp via the Phoscon web app, but I have no idea how to get the right parameters within node-red. The last I tried is to use the node-red-contrib-color-convert to perhaps get the parameters right.

The message sent to the stick is:
{"alert":null,"bri":205,"colormode":"hs","ct":153,"hue":0,"on":true,"reachable":true,"sat":254,"xy":[0.6396,0.3299]}

but shortly after that, I get:
{"alert":null,"bri":205,"colormode":"xy","ct":153,"hue":0,"on":true,"reachable":true,"sat":254,"xy":[0.1336,0.7988]}

It has to have something to do with different color representations, but I do not know, how to get the parameters to the lamp correctly.

I have managed to get the format, I can switch the color. Sending only the xy values as an array to the xy node will do.
Does anyone know of a RGB to XY converter? I use homee as my control center and have managed to get RGB color information from it.

Hi!

After posting here, I came across that topic, with a code snippet, that helped me. I now have a solution, far from being clean, but it works. Have to clean it up a bit.
