My ISY has stopped communicating with all of my INSTEON devices. At first it was just 4 or 5 of them but today it has stopped talking to all of them. The INSTEON network is fine and all of my keypad buttons work (except ones that need the ISY). The ISY LEDs don't show any RX or TX traffic now. The admin console loads and is communicating with the ISY fine but most of the devices have red exclamation marks for icons. The few that don't are not controllable from the admin console or web interface. I tried restarting the ISY and even turned off the power to all of my INSTEON devices but nothing seems to help.

Sounds like a PLM problem.   Unplug the PLM for a few minutes.   After plugging it back in do a Factory Reset of PLM followed by a File | Restore Modem (PLM) to rebuild PLM.

 

Is the PLM a 2412 or 2413 and how old?

It's a good idea to remove power from the ISY before plugging the PLM back in. Wait a minute or two before restoring power to the ISY. If the modem is a 2412, then you can do that by disconnecting the Cat5 cable.

So that seems to have fixed it. I unplugged both the PLM and the ISY, then plugged in the PLM waited a few minutes and plugged in the ISY.

If it is a 2413S and over two years old. It maybe on the way out. As they have a reputation of failures.

When mine went bad. Power cycling it started it working again for a few days. So keep an eye on it for odd behavior.

Good to know.

 

I do have a 2413S that is about a year and a half old.

 

Is there a different PLM that is recommended now?

If you purchase directly from SH all of the current shipping PLM's will be hardware 2.0 with firmware v.9E. Hardware 2.XX has addressed the early failures by identifying bad capacitors and replacing them with higher quality ones. The v.9E firmware has removed the ALL ON / ALL OFF commands from the data base which seems to impact a small segment of users.

 

NOTE: UDI is currently testing their own PLM replacement unit. Expected release is Q1 or early Q2 of this year.

If less than two years old. As pointed out you are with in the two year warranty and it should be covered by Smarthome.

I had Smarthome replace my PLM and that fixed everything.

 

Thanks for the help.

So the new PLM is became unresponsive over the weekend. Unplugging it wasn't enough to fix it this time. After the first factory reset the restore failed. I tried a second factory reset and restore and it worked. The PLM has been working since. Could anything cause this or did a get a bad PLM?

 

Where can I find information about this UDI PLM?

Of course anything is possible but it seems unlikely a PLM less than a  month old would fail with capacitor issues.

 

What does Tools | Diagnostics | PLM Info/Status show?

What does Help | About show for Firmware Level ? UI Level?

PLM Info/Status: 33.5E.86 v9E / Connected

Firmware: v.4.2.22

UI: v.4.2.22

 

It became unresponsive again this morning. The PLM status showed connected but when I restarted the ISY it booted in Safe Mode. I unplugged the PLM for a few minutes and restarted the PLM. Just like last time the ISY connected to the PLM but couldn't communicate with any of my INSTEON devices. It took 3 factory resets this time to get the PLM restore to work but like last time everything is working after a successful PLM restore.

This does sound like a failing PLM to me.
