Yes, the RGB and white temp set weird colors when setting them from HASS, thats on a RGBW strip. I also have RGB+CCT and just CCT strips that have issues. From my basic searching, it was from HASS and WLED devs not agreeing on things, which turned things sour, and now no one wants to fix or manage the translation from/to WLED/HASS (maybe im wrong about this?).
Ill try tackling it next week as I am porting my standalone MQTT project over to a HASS add-on this weekend.
