Re: The problems with X10 ...

["accidental plumber" <aplayerinla@xxxxxxxxx>]

I always wonder this: have you unplug all your electronic and
electrical appliances and tested?

Because your neighbors typically have the same things as you do.  If
you have a clean strong signal in your house, it's harder for outside
devices' effect to travel far and affect your house.

The exception is brownouts and power surge.  Brownouts are hard to deal
with unless your device have high capacitance to buffer momentarily
brownouts.  As far as noise goes, the chance of looking like a valid
X10 code shouldn't be likely, unless it's constant bombardment, not
surges.
