As a newbie to HomeGenie (in experience, not time) I had developed a certain cockiness as to my troubleshooting abilities in HomeGenie and X10. Recently, I learned I was wrong.
I have a older small house with detatched garage/workshop. In the last few years I added some simple X10 automation devices, LED bulbs and tubes and motion detectors. This has allowed me to maintain some independance and freedom. Imagine my concern when the automatic shop/doorstep lights began operating erratically. And then basement lights. and then some of the other convience item I had installed.
After several months of head-scratching and frustration. I accidently left my HP laptop power supply unplugged and everything was suddenly cured (I hope)
This simply shows how a simple solution can save frustration.
It had been indicated how powerline noise could affect X10 and now I truely believe.
When the laptop is plugged in now it is into a filtered powerbar like the rest of my electronics.
