Summary: swapped ISY to EISY, tried new USB PLM, swapped back to Serial PLM, maybe Deleted modem, now screwed...
How I got here:
Got an eISY to replace my ISY994. Also bought a new USB PLM
Did the swap over from the ISY to the eISY. Initially started to use the USB PLM, then realized I could use the old serial PLM with less efforts.
Seemingly got everything working correctly.
When adding a new Insteon scene I think I might have accidentally hit the "Delete Modem" command
Devices didn't respond to commands, so I did various permutations of Deleting/Restoring the PLM, Restoring devices, etc
What I get now:
the eISY can connect with the USB PLM and some of the devices will respond.
When starting the admin console I get "Failed communicating with" errors for 8 or 9 devices (devices I think I tried to communicate with when the serial PLM was attached?)
What I think has happened:
It feels like I've got parts of 2 PLMs in various link tables in various devices and the only way to 'fix' this would be to start over.
While I have read and re-read the Restore/Delete PLM user guides, I can't seem to figure out the correct process to nuke all the links in the house, ensure I've only got one PLM in the system, and rebuild from the admin console.
Any help appreciated!
