Thanks! That was what I did in the first place to set up the new ISY, but somehow doing the same thing again resolved it.

It seems there's one link in each device that's not the same, and restoring the device doesn't change that. For example, I have: Device: <isy.diag><title>Device Links Table : Office / 1A 17 13 1</title><insteon.lincs><eventInfo> <ix>0</ix> <ad>4088</ad> <fl>162</fl> <gr>0</gr> <id>3905241</id> <data>16719617</data> </eventInfo> <eventInfo> <ix>1</ix> <ad>4080</ad> <fl>162</fl> <gr>19</gr> <id>3905241</id> <data>16719617</data> </eventInfo> <eventInfo> <ix>2</ix> <ad>4072</ad> <fl>0</fl> <gr>0</gr> <id>1834330</id> <data>16719617</data> </eventInfo> </insteon.lincs></isy.diag> ISY: <isy.diag><title>ISY Links Table : Office / 1A 17 13 1</title><insteon.lincs><eventInfo> <ix>0</ix> <ad>4088</ad> <fl>162</fl> <gr>0</gr> <id>3905241</id> <data>16719617</data> </eventInfo> <eventInfo> <ix>1</ix> <ad>4080</ad> <fl>162</fl> <gr>19</gr> <id>3905241</id> <data>16719617</data> </eventInfo> <eventInfo> <ix>2</ix> <ad>4072</ad> <fl>0</fl> <gr>0</gr> <id>0</id> <data>0</data> </eventInfo> </insteon.lincs></isy.diag>

I've upgraded from an ISY-99 to an 994 and also replaced the modem at the same time. (Turned out the modem was broken, but given the age of the ISY I chose to replace that at the same time.) I restored from a backup. There is a remaining problem: The ISY doesn't seem to notice when a device gets manually switched on or off. The device's status doesn't update in the ISY and programs don't get triggered by devices. If I manually refresh the device status or switch it from the ISY it works fine. So it seems the ISY can talk to my devices, but it doesn't listen to their messages about a switch being pressed and so on. Any ideas how to fix this?
