Hi Dave,

I wasn't thinking anything that complicated.  I believe the original poster
was looking for a system where his "housecode" would be different from
others on the street.  I do not see a way to do that without modifying the
receiving modules.  The easy solution is a whole-house blocker.

Another poster commented on stray RF commands from neighbors.  Here is where
the CM15A can help without getting too complicated.  I'm not suggesting
security at the level of entry systems.  Just a 2 or 3 code press within a
time window to enable relaying a received RF command to the powerline.  The
goal is to prevent neighbors stray commands from controlling his X10
modules.
