I would like to replace 2 conventional light switches in a 2-gang box, with 2 "smart" light switches, but I'm confused about how to wire them.
The circuit has 3 wires coming in from the top conduit: orange, white, and black. And 4 wires in the bottom conduit: yellow, red, white, and black.
The smart switches want red (load), black (hot), white (neutral), green (ground).
My questions are, where is the green ground wire? (This is new construction within the past 3 years in the US.) And, based on how the existing switches are wired, how should I connect the wires to the 2 new smart switches?
