I don’t know why I am having such a tough time figuring this out but can someone explain this to me like I am a 5 year old.
What is the main purpose of a add-on switch?
I have a four switch outlet in my entry way and I want to put a GE smart switch to replace one of them to automatically control my exterior lights. I don’t need smart switches for the other three but I do need to replace them to make them all rocker switches. Can I just put regular switches in those other three spots or do I have to use add-on switches?
