Wire 2 GE smart switches to 2 different lights on the same circuit
I had the same exact issue. Physically pressing the button controlled both lights, and I could use the app to control them individually. I thought it might be wiring related too.
Solution: Move one of the switches into its own 'Room' in the 'C by GE' app. Create a new Room, and assign one of the switches to the new Room (that automatically moves it out of the previous Room). Presto! Each wall switch now only controls its specific switch. This seems more like a software bug because the solution is not a logical fix, but it worked.
