    How do I wire a 3-way Zooz Zen21 smart switch?

    The following dead-end 3-way wiring diagram shows my current setup with the Zooz Zen21, but it's not working. This wiring works fine with a simple standard paddle 3-way switch that doesn't require a neutral wire. However, since the Zooz switch requires a neutral wire, I ran a white wire from the...

    Can't figure this out this 3-way switch for the life of me.

    I know this is probably very simple for a lot of you, but I just can't get it to work right right. I've been close, but no cigar. I disconnected the switches because I painted the walls and I can't remember how I had them wired. There are two 3-way switches that control two exterior lights...

    3-Way Switch Loop, Ceiling Fed Multi-fixture Wiring Puzzle - Need Help

    This weekend I was replacing a hall light fixture in my old home (rewired circa 1980/90's) and noticed the work was done using one of the exposed ground wires as one of the switch leg/loop travelers on a 3-way. Obviously, this is completely wrong and a fire hazard, so I decided to try to rework...

    I have a staircase about 25 feet long with two recessed lights (one up top, the other at the bottom). Each light is on its own 3-way switch, which is ridiculous. I want to combine the lights so that one 3-way switch controls both lights. I tried to wire it up so that each corresponding wire...

    3-way switch issues. Can you blow a “switch”?

    I took a light down to put up a new fixture and now the light goes on but the switch doesn’t shut the light off. The power only stays on so I am quite confused. It is a 3 way switch. Both switches will not turn the light off. The wiring “appears” to be 14/2 to fixture and 14/2 out of fixture...
