I know that X10 and AHP is flaky, but this makes no sense. I'm trying to turn on 3 lights in the evening. Set up timers, everything works, except one light won't come on. So I read the posts, did all of the possible fixes (cleared timer, emptied the trash, started over with a new program, disconnected the CM15A from the computer, moved it to various wall outlets, clicked the box to store timers in the interface, asked for repeats, etc., etc.) Decided to set up the three lights on the same code just to make it easy. When I ask the software in AHP to turn on the lights, they all turn on. When I use the remote, all three lights come on. Set up the timer, download the code, turned off the computer, moved the CM15A, the timer does its thing and turns on one light. Other two don't come on. I assume the CM15A sends the same signal through the wiring if the software comands an ON, if the remote comands an ON, or if the timer commands on ON. Why does only one light come on when the timer makes the request. And if I turn on the other 2 manually, the timer is able to turn all three off. Totally stumped.
