Shelly rgbw2 and shelly binding do not provide support for CCT Led Stripes where you only need two channels (cc and cw). So I am currently thinking about a workaround:
My first idea is a dimmer item for channel#1 brightness (shelly device type set to white control) with a rule that channel#2’s brightness = 100% - channel#1.
A second slider would control the total brightness e.g. if this slider is set to 25% then channel#1 and channel#2’s brightness in sum will be 25%.
Not sure if this would work seamlessly.
Anybody has a different idea?
