Do I have, again, a broken PLM ??

[gaetanlord]

Hi

 

My ISY is accessed via Home Assistant to only control devices. All was working fine for many months until  this morning.

I initially thought I had an issue with Home assistant, so I fire up the  administrative console, but no luck. ISY cannot talk to any of my devices. I reset the PLM and reprogram it, still the same issue.

My PLM is only 1.5 years old, was already replaced twice in the last 7 years. I thought by having a 2.4 version would  free me of those problem, for at least 3-4 years, but seem not.

Before going forward, I would like to be sure I have a bad PLM, I include below a log output.

When I check for the PLM from Tools -> diagnostics -> PLM status, I only get connected.

The "reprogram" seem to have working fine.

Nothing change on the electrical side.

 

At this point I'm clueless on what I should do next to confirm a bad PLM, which do have a green led "on". Any advise

 

Regards

@gaetanlord,

If the PLM light is lit, the first thing would be to move the PLM to a different outlet and one which is not shared with other transformers and power supplies.

With kind regards,
Michel

The revision 2.4 PLM. Has the updated Serial Port Daughter Card with better serial signal protection and C7 and C13 are now a capacitor designed for switching power supplies.

You may want to try it in a different location, look for a newly added electronic device maybe causing electrical noise or absorbing the power line signals.

Well,

 

I was about to move my ISY/PLM to another location but test once again. All is back to normal. I change nothing, I wonder if a good night was the answer. All I could say is for 6 hours it didn't work last night and nothing really change. I did try resetting the PLM and reprogramming it as a fix maybe that was the answer, but i swear, that it didn't work after that. Sorry for this inconvenience.

As usual, thanks for the quick feedback. A good reason to use ISY

Regards
