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.
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?
