Thank you.
I found it out by accident. My wife collects Nativities and one of them is a led lighted one of the Holy Family. It's battery operated and a local electronics store supplied the proper power supply to use AC power instead of batteries. I took the unit to the store, and one of their staffers figured the proper places to sotter the two wires (after cutting off the plug leads) and once that was done, it runs off AC, so next was the Appliance Module, which was given the same address as the other Nativities (which there are 5 of them) B6. First time the timer ran, 5 lit, the Appliance Module did not trigger unless I unplugged it and plugged it again. So, the AP got reassigned to B12 and all my .ahx files got modified with the new module.
