I had a situation today where none of the motion sensors were signaling status to the ISY. I couldn't see any problem with the ISY itself so I just went down and unplugged the 2413S and plugged it back in. And things all started working again.

 

I've had a couple of PLM failures in the past that required replacement. But I've never seen one lock up like this, or at least that's the only explanation I can see. Does that happen? Is there any experience to say it's getting ready to fail?

 

I did note when I unplugged it that the (normally white) LED flashed red very briefly, which I've never seen a PLM do before.

Hello ergodic,

 

Please see this post:

In some cases, also, we have seen that factory resetting the PLM simply causes it to go to a mode where each command just causes it to sound a long beep.

 

With kind regards,

Michel

Thanks Michael. I'll watch that thread for a resolution.

 

I'm hoping I won't have to get yet another PLM (not to mention the spare one I keep.)

 

For now I've moved the PLM on to the power strips controlled by the big red power button that I've told my wife to press when things don't work.
