Brand new to SmartThings – just set up my hub today, in fact! First order of business was installing a GE 12727 smart switch. Thought this would be easy. I was wrong I’ll post pictures below, but when I opened up the gang box I was pretty darned confused on what was going on back there. A couple issues:
The GE switch requires a neutral. My fault for not researching, but that’s another story! I see a bundle of white wires nutted together in the back of the box. I’m assuming they’re neutral and I could just run the jumper out of there, but wanted opinions. I got “life” in the switch doing it that way during my experiments today, but I don’t want to put a fire hazard back in my wall, lol…
You can see that the existing one pole switch I’m replacing is apparently being used to power the adjacent 3-way switch (and something else?), because there are 3 connections to 2 terminals (2 screw-in and 1 push-in), with one being like a “piggyback” that branches off to the other switch. I tried wiring the GE switch in the same manner, with one on the nut and one in the push-in, but it didn’t work as expected. The “push in” connectors are not the same as on the cheapie switches, and I’m not sure you can use them simultaneously with the screw-in.
I messed around with the GE switch today, and no matter what combo I used, one of the lights powered by these two switchs would always only turn on if the other light was in the “on” position. Whereas right now (the old wiring pictured), they’re independent of each other – one can be off, the other one…and vice versa. Hope that makes sense. I’m wondering if that’s simply a limitation of the new switch. In which case, I’m wondering how I remedy that. Would some type of pigtail need to happen?
Any advice/help is appreciated!
