Brian, need your help again. I've hooked up some WS4777, 3 ways, and so far so good. But now I'm in the kitchen and the existing switch has 4 wires on it, 2 red, and 2 black, instead of 3. Not sure why. The other 3 ways had 3 wires, and a ground, this one has 4 wires and a ground. The WS4777 only has 3 wires coming out of it. Not sure what to do. This switch can be controlled from 2 other places, plus the master.
EDIT, nevermind, I found out that you jus cap off the 2nd black wire and it won't be used.
