I've recently noticed some strange motion sensor behavior that I'd like to run by the experts here. Very basic MS/outlet setup and has been working for a few weeks now. The outlet in the scene has a lamp connected to it, the MS is wall mounted directly above the controlled outlet about 8 feet.

 

Shortly after added another hard wired outlet on an exterior wall to control the some front yard Christmas decorations I notice the rapid LED blink on the MS. I understand this means the sensor's inability to reach another device in it's link table. The trouble is the MS is right above the device it is controlling. If I move the MS 10-15 feet the blinking seems to stop.

 

Could this be an interference thing? Could this be related to related to the outdoor outlet?

I could be if the lights are in the MS FOV. It could also be a low battery.

The light interfering was a thought but I've moved the sensor to a number of different locations with the same result. Replaced battery no luck. I'm thinking it could be defective.

I have had trouble with this. The flashing multiple times with motion indicates a weak battery. After replacing the battery this can persist at times. On some I have had to do a factory reset and others it seemed to correct itself later.

 

Try tapping the link button several times after battery changes and observe the ON and Off signals are sent alternately. This may cure the lingering status.

Thanks Larry. I've monkeyed around with link button to see if that sorts things out. I'll know at sunset.

Check to see if there are pending updates to the device (green 1011 icon.)  This thread, motion sensor blinking question SOLVED, might offer more.
