Thanks for this thread, I just lit my V2 up with one of the very first goals of being to slave two dimmers via Smart Lights (I wanted to use Big Switch). They will work together as a 3 way, but the dimming seems borked.
My question is, has anyone seen Smart Lights actually do group dimming successfully before the poltergeist invaded?
Not before,nor after the ghosts were set free, at least for GE and low priced Leviton dimmers. There were reports by some folks that some dimmers worked for them with Smart Lighting, but certainly none of mine.
I’ve got a pair of Leviton VIZA dimmers and they seem to /try/ to work, but since I set up the Smart Lights in two directions (front of of tied to back AND back tied to front) it seems to be arguing with itself. I’m disabling one of the Smart Lights instances and see how that works.
The three way on/off itself works great and the delay is about 0.5 --> 1.0s delay, which is acceptable for my use case.
