I have a couple of rules that use fade over time to changes dimmers from 0 to 100 and the bulb color from daylight white to warm white. Currently I need to do this in two steps: first to change the dimmer level, and then using a transition scene to gradually change color from one white to the other. It would be cool if I could do this all in one step. For my use case, I don't really care what the beginning color of the bulb is, as long as I can end up where I want to be.
