Hi!
I’ve created custom light component for lights that support color (rgb, hs or xy) but doesn’t support color temparature (like some IKEA Tradfri color bulbs). It was necessary to pick white light from color picker for such bulbs… With this integration you can pick color temperature from original HA UI color temperature picker or use color_temp property in service call.
This is basically copy of HA core light group entity component, but with support for only one light entity and forced SUPPORT_COLOR_TEMP feature (light group also emulates color temperature but only if at least one light that supports color temperature is added to group…)
