I’m about to install a Z-Wave switch in my house and it’s a house from 1972, but was completely renovated and to my pleasant surprise, it has the white wire I need for this. The question is, looks like the wiring is non-standard coloring and I use this loosely since there is no real standard in the US apparently from what I read. For the below, I will be able to find the hot wire, but how do I determine what the other two wires are before connecting them to the new switch?
Anyone know? So I guess I can detect the load and the neutral. But then I guess there is a line and ground? Hopefully if I can find out the switch model I can find a document that shows what each connection is right now.
