Replaced PLM now flashing motion sensors

[raymondh]

My 2 year old PLM started sending all off commands then quit completely so I had to replace it.  I have a bunch of motion sensors that are only used in programs (they don't directly control anything).  I put them one by one into link mode and connected them to the new PLM like the instructions on here say when replacing PLMs.  They all work but a few of them will flash a bright red LED several times after seeing motion.  Insteon's troubleshooting says that indicates a communication issue but I've never seen it before and things seem to be working as well as they ever did with them.

 

I've tried putting them in link mode and restoring them but that doesn't help.  Any thoughts?

I thought it indicated it sees motion.

There's the normal dim fast flash for motion then there's the bright long flash that means something else.

It means your batteries are going dead.

It means your batteries are going dead.

You're a battery.

I've tried a few batteries (from different packs) in the ones doing it.  Doesn't change.

I have one that I had to factory reset about 5 times before it behaved. Now when I change the battery I have to factory reset it again. My other 9 units work without this.

There several conditions which causes the MS to flash.

 

1. Motion detected

 

2. Low Battery

 

3. Unable to communicate to a linked device either because of noise, not present, or defective hardware. This is also due to half links that may reside after a failed add / remove process. 

 

4. Pending write: The system will attempt to write any pending writes if auto writes have been invoked in the controllers.

If it flashes continuously, then it's having issues talking to a device. You said you paired it, but what you really need to do a restore and get rid of the old PLM, that's probably why you're seeing this.
