That black wire, looped around one switch screw and continuing to the other switch (conveniently highlighted yellow in your last picture) is the "hot" power supply coming into the switch box and eventually makes its way back to your breaker box.

So what's the right way to wire this? Neutral into the red wire nut with the other neutrals, connect each black wire on the left toggle to the 2 black ones on the Kasa (does order matter?), and get the ground wrapped up in the green wire nut with the other grounds? What happens to that one extra black wire wrapped around the screw (and exposed there). I wasn't expecting to see this and am not sure what it's for or why the 2 switches that are unrelated are connected.Įdit: the right switch is part of a 3 way switch if that matters.Įdit 2: Added image with coloring to hopefully make the wiring more clear.Īlso one ground wire runs through both switches and then up into the end of the green wire nut. But theres that other wire on the side that's looped around the screw and connects to the foyer switch. Then there's the bare ground wire (I believe came off when removing the switch). When I opened everything up I found the toggle switch has 2 black wires coming out of it. The right switch is the indoor foyer light. The left switch is the porch light I'm switching out. I'm trying to switch out an existing one way toggle switch for the Kasa HS200 smart switch.
