Comments

Tried to write a custom controller for it to not expose "color_temp" but to just have white as second option to RGB but failed because of lack of knowledge. The model that I have is "5 pin RGBW", so it doesn't have color temperature (2000-6000K) but only has RGB channels and a single white channel.

It's more of a problem than new device support as more as I think of it. Had to emulate over Node-Red and template light to get it to have sense.

I have the bulbs for testing purposes if needed. The fingerprint is the same but the bulbs have firmware version 1.0.13/20201216. The fingerprint is otherwise identical unfortunately.

[zagi988]

Can anyone at least help me write a custom controller since the fingerprint is the same?
