I am having a problem with my new X-10 system. I started with the IBM Home Director kit, (which I know does not have the best modules) but what is happening now, is that my lights will mysteriously dim or turn themselves on and off without any intervention.

I have changed house codes with no change in behavior. I thought that it might have been related to my AC clicking on and off, but with controlled tests this did not reproduce the problem. Different outlets don't matter, as I have devices on both phases of the house in different areas with the same problem.

I am awaiting the arrival of some high end PCS switches so I will experiment with them to see if the problem occurs.

How can I prevent this behavior from happening, it is driving my wife nuts. I don't think a signal bridge will help as the on-off commands get through without a problem. I think it might be related to noise in the electric lines, but how do you filter it out.

Thanks in advance for all of your help.
