I need help. I have a light in my kitchen that two switches in the room can turn on and off. I followed the Jasco 3-way switch instructions to a T. I used my multimeter to identify which switch was line and which was load and labeled accordingly. After rewiring the line switch with the new GE Z-wave Smart Dimmer (14294), I went to add the new GE Z-wave Add-on Switch (12723) and got stonewalled by the lack of neutral. Every other outlet in our house is wired with a neutral wire, but this one box. Maddening! I wish the video would have advised me to check for neutral in both boxes before continuing, but c’est la vie.
I did not get great pictures before rewiring to my new switches, but once I was stumped I took a picture of the old switch with the wires hovering where they were previously rigged up. I put wire nuts on them and turned on power just to see if the new Smart Dimmer switch would work. To my surprise, the blue LED lit up and I was able to add the switch to my Smartthings hub. Oddly, it does not turn the light on/off.
Here are pictures of the line switch wired up to the new Smart Dimmer:
Note in the second picture the neutral wire. In the third picture, you can see the black load wire going to a wire nut, what might be hard to see is that the wire is black going in but appears to go out white.
Here are pictures of the load switch where the Add-On needs to go:
Please help! Let me know if you have any questions. Very much appreciated.
