So I have been adding smart switches to my house and imit has gone really smooth up until now. I have come across a switch without a common wire. This is a 3 way switch where one switch has a common wire and the other side does not. I know I can install the GE smart dimmer on the common wire side, but is there anything I can do with the other side? I have the GE add on switch but that won’t work without the common wire. Are there other addon or even a dumb switche that would work?
FYI there is no attic access to this room.
