I have used a 994i and insteon PLM for many years with no difficulty.
I have installed a new eisy and a new insteon PLM. The system seems to think it is connected. I can create programs and control devices.
If I create a program to operate the switch at a specific time, it works as I would expect it to.
I have written a program to turn a switch on at sunset plus 5 minutes. When I look at the summary and "next scheduled run" the time is not sunset plus 5 minutes but shows as approximately sunset plus 12 minutes. When run time arrives, the switch is not activated. I have deleted the device and the program, added them back and the same thing happens.
Any help would be appreciated
