Aux switches require only 2 wires. That’s what makes them attractive when wires are limited.
Yes, I’m starting to appreciate that… I’ve also pretty much figured out that I won’t be able to get by with the dumb switches in there, which is ok in the end.
I should at least remove the face plates another time to make sure I didn’t mess up the drawing 
I don’t know if the Decora will work. The text suggests it wouldn’t.
Why do you think that? I saw that suggested on this thread and figured it should be ok (without scenes). I like the looks better than the GE ones, that’s why I had hopes on these.
