Here's my set up:
1 outside light connected to a WS4777 Three-Way Master and Slave
1 outside light connected to a WS467 single switch
1 MS16A motion detector, set to turn the lights off after 10 minutes
of no motion
1 RR501, set to communicate with the MS16A and send it's on/off
signals to the switches.
This set up has work fairly well for over a year, although I
occasionally have an issue where the lights will stay on indefinitely
as if the RR501 is not receiving the OFF signal from the MS16A.
Well, last week I needed to use the garage outlet where the RR501 was
plugged into, so I unplugged it. I assumed that the outside light
setup would no longer work since the RR501 was no longer controlling
Well, much to my surprise, the lights come on when motion is detected
and 10 minutes later (assuming no motion) they go off. How is this
happening? Does the MS16A communicate directly with the switches,
meaning that I never needed the RR501 in the first place?
