I have three lights in one room that were all purchased with a dimmer switch, thus three lights and three switches. I later bought a hub and followed the instructions to link the switches (Accessories) and their bulbs to the hub. All seems to be right and I have individual control of the lights through the app. However, now any of the dimmer switches now controls all of the lights simultaneously. I have not seen anything in the app to maintain the individual bulb and switch assignment, is there some way to do this I have not seen. Or is there a work around? I was thinking to make individual rooms for each of the switches and bulbs, but then I would not be able to turn them all on or off with a single gesture or voice command. Is there a better way to do this? Thanks for the help.
