I have had ISY running programs that haven't been touched for close to 10 yrs. now. We had a power failure (days) and supplemented part of the house with a generator. When the grid came back up, my programs that check the status of an Insteon light switch stopped working. If I run the program from the "IF" part in the ISY Admin Console, the program works. In this instance I turn the switch on from the ISY Admin Console. If I turn the Insteon switch on / off at the switch, the program will not execute. The program's are very simple. Check the status of the switch. If it is on, then wait N minutes and turn the switch off. I did a screen grab of the program below.
All of this was somehow induced from the power going out. The ISY994i seems to be working fine as I can get into from the ISY Admin console. Programs that are based off of time of day work fine.
Anyone have any ideas on troubleshooting this?
