Donald:
I have had exactly the same experience as
you. First one wall switch failed to work,
then another and another. Then the command
module stopped working altogether. Now I
find that the external security lights turn
on almost at random and won' turn off. I am
about ready to rip out all of the X10
products, cut my losses and go back to
standard switches/lights. I have called the
help line numerous times and they have
pretended as though this is the first time
they have ever heard of this. And yet in
various internet forums, I now discover that
this is not unique to me at all.
When you first purchase, there is no mention
of the need for X-10 filters! Nor is it
reasonable to suggest that this product will
no longer work if you change a light bulb or
plug in a different appliance. In a few
parts of the world, power companies are
transmitting telephone and TV signals across
power lines, so how X-10 cannot handle a
noise within one's own home I don't
understand. If the technology is not that
robust, then I think it is time to switch to
something else - maybe wireless, that is not
affected by power line noise. I see that
Lowe's is now selling wireless modules (for
outdoor security lights) that would work in
place of X-10.
If you manage to fix your problem (other than
through random trial and error, which I
resort to) then please post here how you did it!
