What about controlling color_temp for tunable white bulbs? Did you happen to implement it before?
I guess it would work the same way as brightness - so you may just fork it and add the options you need for your installation.
hm, but color_temp only accepts mirads as input, not steps. I think we need to convert it somehow.
Depends on the actuator, I guess. The ones I know support DPT 3 color temp dimming, just like brightness.
And HA supports Kelvin too, so no need to deal with Mireds afaic.
Yeah, kelvin should be fine for Phillips Finance white

@Reteip10 right, use
expose
. This blueprint only has one-way communication.Or fork the blueprint and add it 😉
