Hey diy, I have a question about installing a motion sensor switch in my upstairs hallway. It is an L shape that goes past 3 bedrooms. It is a 3 pole switch configuration so a switch at each end. My question is do I need to replace both switches with motion sensor ones? I have seen the wiring diagram but it never talks about if you use 2 or not? via /r/DIY http://ift.tt/2uo2ajT
