I am having a really strange problem whereas newly installed GE smart dimmers are failing in different ways. For context, I have installed about 15 of these in my house so far. Basically, I know what I am doing in terms of wiring.
After installing the first dimmer (version 1) I was unable to use the physical switch or SmartThings to turn off the lights. It would dim them down to about 5%, then act like they were off (off in SmartThings and light on the rocker) but clearly the lights were still on.
Because of that behavior I thought that maybe the dimmer was faulty, so I purchased the updated GE dimmer (version 2). This time I got an even more strange behavior. Anything over 68% brightness causes the light to cycle on and off gradually raising brightness to a point then starting from off again.
I’ve tried to change all of the bulbs thinking that maybe one of the bulbs is bad, but that hasn’t helped. They are all basic LED “dimmable” bulbs and there are 4 on the circuit (can lights).
Can anyone explain what I might be seeing? I feel like this must be a wiring problem, but that really doesn’t make any sense. There is no way that two of these switches are bad back to back.
