That is funny. That is what I was coming to the conclusion.
The problem is that the scene executes at the scheduled time (it just did). But 4 of the devices are not turning on, but 6 of the other devices in that scene are.
The 4 devices that are not turning on are all 1kW SwitchLincs. The other devices are either plug-in modules or sockets. All devices are Insteon (no Icon).
Is there something else (other than telnet) that I can use to monitor the execution of the scene that will help me determine what is going wrong?
