dave w yeah it's driving me crazy as to what is the problem. While it could be me, the activity log shows a ton of signals sent at the times things are supposed to be going on, so I'm at a loss. One would think if my units are of the wrong module type, they would not work as they do with auto-off and manual on/off. What's confusing as hell is if the command is coming out of the program to go on, how is it not "passing through" the CM15A like it does for auto-off and manual on/off? Makes no sense but I'm ready to give up. I did delete all the modules and erase CM15A data stored. I will re-enter some for tonight and see what happens. If still nothing then maybe I will take you up on the loaner offer. TY!
