I added a GE Zwave dimmer and add on switch in a 3 way with can lights.
The lights work great. I used a wiring diagram from this site.
But…I ran a pigtail from the red traveler at the add-on switch and ran it down to a receptacle I needed in the hallway.
Now…the receptacle tests as “correct” with my tester, but when I plug anything in…it doesn’t work. Plus, if I plug something in the bottom AND then tester in the top…the can lights turn off!
