OK- finally back in town to try your suggestions. Did the count and got 0. Tried the restore, it ran awhile, then came back with an error that said "Driver not found". So now what?
I originally thought I had a communications issue except I can get to each device with a manual on/off command. The issue is my automation has stopped however if I power cycle the ISY, the commands are sent and the devices respond to the current state of the scenes. The devices then stay in that state until I power cycle again. Suggestions appreciated.
