Hey I have ran into an issue where GE advertises that its smart switch can be installed with and line load and ground. They also claim to be able to use the same configuration of wires supposedly to become a 3 way switch, besides that I'm trying to use the motion sensor switch for a bathroom vanity and it's not seeming to hook up to the light or preform properly with the light control settings. Basically it wants to link up with the wifi and the app, but instead just turns the vanity lights on and off... I curious why it can't just preform like a typical switch until it its engaged to the wifi or app. Any how I had to install and uninstall these all day all over the house it seems. Most curious is the bathroom situation. It only askes for the line load and ground, i gave it what it needed and it has a blue light issue at the switch. How can this be resolved? Shouldn't just be able to be link up with the app and be good to go, but instead it has become a smart problem I am not stoked on, back to my 3way deal has anyone successfully used this 2 wire to fulfill there 3 way smart switch replacement? I'd like to know, seems interesting....
