[Feature request] Allow per Channel Device Type for RGBW2 and include Fan
I'm using the RGBW2 to control some low voltage fans. It would be great to have the option for per channel config of what the device is. 

Currently, it shows in homekit as a light (which makes sense given its primary use) but would be great to be able to specify per channel the type of device (similar to the switch types) and have fan as an option to specify.
