Thanks folks for all your replies, I will look into all your suggestions. I AM guilty of leaving cell phone chargers plugged in, on a switch in the bathroom, that is directly above the outside wall switches I am having problems with, coincidence? Do not know, but will unplug and see, I DO know,, that some security lights that I have, that are 150w fluorescent lamps WILL not allow 90 percent of my x10 devices to work, even though they are WAYYYYYYY outside in the front of the house. I no longer set them to automatic, have them turned off, and that helped a lot.
IN RESPONSE TO dave w yes the light switch worked with a sensor at one time, then slowly went south, the sensor would turn it on not off, I could turn it off with the remote or AHP from the puter, then not even that. I will switch it out and see
It's behind a VERY heavy storage closet), so I was hoping I wouldn't have to do that, but will do so tomorrow. And nothing new has been added, I do not even have my puter hooked up to a UPS because I believe those cause havoc with the AHP interface. I DO have 9 security cameras (NOT X10)that go directly into the computer (hardwired) could those be an issue? Should I remove the AHP interface from the computer and see if that changes any thing?
Now, is it possible to build a phase coupler? Reason I ask, is I mentioned that and a noise filter to my electrician and he was like HUH? (you must understand though I live in South America so perhaps I didn't explain the term correctly ) A repeater at the panel was mentioned, forgive my ignorance, but what do you mean by a repeater? Also, I have several of the RTM75S around the house, because I assumed that they would boost signals...would that cause a problem?
I REALLY appreciate any and all help, I had X10 when I lived in the states, and NEVER had a problem, that is why I invested a good chunk of money into another x10system here in South A.
Be patient with me guys, I normally don't like to bother people with these things but the forums are much better than tech support (sorry if there are any x10 tech guys here) but those are the facts.
