- exodust 12y agoOk, thanks for the useful link (I think). When I played with wireless door sensors and Arduino, detecting door state reliably wasn't happening. Maybe it's the wired vs wireless factor that gives yours the edge. Maybe that's the trade off to know open/closed state with certainty, is to use wired sensors.
