Control W Channel of RGBW2 independently
**Is your feature request related to a problem? Please describe.**
When setting color it works as intended, however if I go over to temperature it uses the RGB and w channels in conjunction to produce the desired temperature. And there is no way to only control the W channel/only have that one turned on.
**Describe the solution you'd like**
Show the RGB Channels as one Device and the W as a separate one. So it is possible to dim the W Channel and have only "pure" White light. If possible only in one device but I don't know if HomeKit supports that.
