I have been using Indigo and Insteon for at least 2 years now and everything worked perfectly until the last few months when Insteon has started giving me problems.
About twice a day, I get Interface Connection Failure. In the Log, I see: (not in order)
PowerLinc
Unexpected command 02 62 (flushing)
Error
PowerLing not responding -- attempting reset
Application
PowerLinc address 33.E2.2D, firmware version 9.14
Interface Failure
lost connection with interface
Error
resending previous command (busy or unexpected command). - I get several of these in a row.
Cynical's insteon water leak add on has been giving me lots of false alarms
I also have a trigger that alerts me when the power goes out. I have been getting lots of false alarms on this too, and it usually coincides with the insteon errors.
My PowerLinc is plugged into a UPS. I know it is advisable not to do that, but it has been like this since day 1. I tried plugging directly and it didn't solve the issue. The powerlinc is connected directly to my Mac mini.
I should also say that very often these errors happen when I turn on/off an insteon device (via its own switch) that has an associated trigger with it.
Please help.
