We have an RGBCW lightbulb (full color control), and a dimming
lightbulb (no color control), this covers the in between case of a
lightbulb supporting cool-warm white adjustment, but no other colors.

 ### Lights
 
+- Generic CCT lightbulb (supporting color temperature and brightness)
 - Generic dimmable light (2 types, using dp 1,2 and 20,22)
 - Generic RGBCW/RGBWW lightbulb (confirmed with Lijun branded bulb, expected to match others also). Three versions - standard dps layout starting from 20, with and without scene/music modes and timer, and a non-standard layout starting from 1 but following the same pattern (tested with "A60" bulbs).
 - Generic RGBW lightbulb in the non-standard pattern above but without color temperature control.
