There is a light switch that controls some recessed lighting that I want to replace with a smart switch https://www.belkin.com/us/p/P-WLS040. The old light switch is a three way switch that is wired as single pole.

  • There are two red wires for line and load on the old light switch.
  • There is two black wires wire nutted together in the back of the receptacle.
  • There is one white wire wire nutted by itself in the back of the receptacle.
  • There is one white wire that is not stripped, just sitting by itself in the back of the receptacle.
  • There are two ground wires twisted up together in the back of the receptacle.

I've tried tying the smart switch line with what I think is line, smart switch load with what I think is load, the smart switch neutral with the white wire nutted wire, and left smart switch ground wire nutted alone. When I flipped the circuit breaker back on, nothing happened. The smart switch didn't "turn on", and pressing the button on the switch didn't turn any lights on/off.

Do I need to strip the other white wire and tie all the white wires together?

  • Can you find the other boxes involved in this circuit and post photos of their innards please? – ThreePhaseEel Oct 17 '20 at 18:23
  • Try swapping the two red wires. You might have the line and load reversed and it will make a difference with a smart switch. – JACK Oct 17 '20 at 18:27

  • @MeestaYeesta -- can you post photos of the inside of the box for the first recessed light controlled by the switch you're trying to replace then? – ThreePhaseEel Oct 18 '20 at 1:00
  • @ThreePhaseEel you mean photos of the wiring of the recessed lights? – MeestaYeesta Oct 18 '20 at 23:36
