I tend to always have fun with the 3-way switch wiring in my house. New scenario where I’m wanting to use either a nzw30 or zen26v2 in the line box. The challenge is the red traveller set is carrying the line from I believe is the light. I put it back to the original switch after my wife was complaining about it… Opening it back up will need a better plan.
traveler set (B/R/W) (Connected to switch)
Pair 1 (B/W)
Pair 2 (B/W)
(B-B from Pair 1/2 Connected, W-W from Pair 1/2 Connected)
Pair 1 (B/W) (top of switch)
Pair 2 (B/W) (B attached common bottom right of switch)
