Kent: I am assuming the electrician wired a
capacitor across the 2 legs of the AC and not
a resistor. A resister would not effectively
couple the X10 signal and would get hot and
waste electricity. If you are interested I
wrote a tutorial on phase coupling at:
http://www.x10.webhop.org/Phase_Coupling.htm Surge suppressors on their own do not cause
problems with X10 signals; it is the
noise-trap that better quality surge
suppressors have that cause problems. I
agree with Arf and you don’t have to have the
module or controller plugged into the surge
suppressor for it to cause problems.
Plugging it into an X10 noise filter will
stop the noise trap from sucking up the X10
signal on the powerline.
Also, devices that have switching
powersupplys can cause problems (either
powerline noise or signal absorption).
Computers, televisions and fluorescent lights
often have switching powersupplys and more
and more other devices are using them instead
of traditional transformers to save
electricity. You can track down the problem
by unplugging (not just turning off) devices
that might cause problems.
