I could use some help with a 3 way installation on a double gang box.
I have three Inovelli Dimmer Switches.
2 switches are for 3-way installations with aux add on. (Using GE/Jasco Enbrighten). One for the hallway and one for the kitchen.
1 switch is for a single pole installation to control the back patio light.
Now, I’m still unsure if my house has a neutral wire or not ( not sure if this is overall wiring, or dependent on wiring in switch box). House was built in 1970 of that’s any help.
However, the reason I’m prefacing this is because I have some older GE smartswitches that work well in single pole applications in my house and I’m pretty sure they required a neutral wire. I installed them years ago, so I’ve forgotten their wiring pattern. I just followed the instructions. They were simple and they still work.
However, I wanted to use these Inovelli’s in more complex wiring such a 3 ways and also was intrigued that they didn’t require a neutral.
I started my project with my hallway 3 way lighting and it seems pretty straightforward. This is were it get tricky…I THOUGHT I had neutral wire, but after attempting to install the hallway lights with the neutral set up, they didn’t work, aux was not responsive, ceiling lght would come on dimly, etc. I even did all the parameters to configure the light for aux add on, etc. I then proceeded to post my issue in a Smartthings Group with pictures and many said my white wires were NOT neutral and that power was coming from the line directly to the light.
So I read on and found that perhaps they were right, because it seemed to be what I was dealing with based on the symptoms, if you will.
Anyway, I followed the diagram below from a previous user and Bry’s comment of "line to the light is common on older homes " resonated with me. So I followed the diagram posted below to the letter and lo and behold, it worked.
My first 3-way install complete…I got excited and figured the kitchen would be no different. After all one of the 3 way switch boxes (where the aux add on would go), looked identical with only the three wires, red, black and white.
Well, that’s where the similarities end. The double gang box has me confused on the way set up with the black wires capped together and white wires capped together (which I’m now unsure if they are neutral or not as mentioned).
I tried wiring the three on what I thought would be correct, but ended up killing the switch. So I had to buy a replacement.
Got the single pole one for the back patio working great though, I just think that I’m in over my head on this 3 way set up due to the "extra wiring in the double gang box. So I went to the home store and temporarily got me a cover for the Inovelli controlling the patio light and just put back the dumb switches for the kitchen 3 way as they were in the double gang box.
So in summary, these switches are great for single pole applications and I also don’t want to kill another switch and make the wife angry again and pay stupid tax by sacrificing these Inovelli’s.
So I’ve reconciled to hiring an electrician to put up my 3-way switch for the kitchen, though if I got 2 out of three Inovellis installed, seems kinda silly.
Out of the recommendation of Eric at Inovelli though, he mentioned there might be some fine folks that could help me out.
So I’m giving this a chance before I hire a pro for just one switch.
Thanks for reading. I know its long but I tried to be as concise as possible.
Thanks in advance for any help you can give.
