Managed to get back to this issue today.
I now have a new non-surge-protected power strip for the miscellaneous things in my computer room. But just to rule that out completely, all that stuff is disconnected.
The CM15A is plugged into a the unfiltered outlet of FilterLinc plugged into a wall outlet on what I will call House circuit A. My APC UPS is plugged into the filtered outlet of the FilterLinc.
An Appliance Module is plugged into a wall outlet that is on what I will call House Circuit 1. A desk lamp with incandescent lamp is plugged into that Appliance module. A PalmPad properly turns the lamp on and off.
I connected the USB cable from my desktop computer to the CM15A and launched the AHP app. I cleared the interface memory, created a On - Off Timer for the lamp, and downloaded.
Unfortunately, timer does not work. I'm at my wits end
