@Guy Lavoie Thank you for all this valuable information! I'm just starting to look into expanding beyond Insteon, so I'm hoping you are willing to help me with a few very basic beginner questions: Are you directly connecting to the GE Cync bulb using the ZMatter USB module for eisy, or is there another hub in between? My wife wants RGB exterior lights that can be programmed to be different colors on different days. I have an eisy with a ZMatter USB module that I haven't even connected to it yet. I'm looking at these GE Cync bulbs. Do you have any suggestions or warnings you think I should be aware of?
