I got some new modules to replace the old ones, hoping to solve some weird/random X10 behavior. This behavior is quite random, mostly the X10 stuff works great for weeks/months, lately some modules do not respond on X10 'on' or 'off' signals. I thought it was related to some very old modules. This period is not related to introducing new electrical equipment which might cause interference. I hardly change anything.
Project lets change modules starts:
After replacing the first module, still the same problems. One of the units is not responding to X10 signals from homeseer however it responds to signals from the RF interface. Other units (same room, same fuse (groep)) have less problems (not fault proof)
Trying to isolate the problem by unplugging device, I discovered the following. Unplugging my audiovisual components the problems disappear. Ok this issue is not new that's why i installed a filtermodule (AFX2). Rotating the AFX2 by 180 degrees (it contains a single coil) give some relief, mr problem module works fine however when i turn on my plasma, "on" signals are 'randomly' processed, "off" works flawless.
Removing or not using my audiovisual stuff is NOT an option

Any experience with this kind randomly behavior?
my house is 'protected' by an SFX40, only one phase (fase).
