ISY no longer communicates with insteon?

[khisanthax]

So I think my isy994 is broken.  From the admin panel I can log into the isy but none of my instead devices are communicating with the isy.  Any time I try to enable/disable isy tells me communications fail.  If I delete a device and try to add it, none of the devices show up in the add/update table.  I thought that my devices might have all died but I connected to the insteon hub and it can control all the devices without any problems.

 

Any ideas on how to trouble shoot? I did a power cycle on the isy as well ... I'm out of ideas and I don't know how long the warranty is?

Try removing power from the PLM and the ISY, then first power up the PLM then the ISY.

 

Are you getting any error lights on the front of the ISY?

I feel like an idiot but that worked.  I never reset the PLM before but now comms are working.  Thanks so much, it's a huge relief!
