Most signaling systems over mains power will actually broadcast as far
as the street transformer that feeds your block of houses.  So be
aware that you need to encrypt such traffic unless you want all your
neigbours to read it too.  If too many people on the one transformer
are using such signaling, it gets so that it will not work well for
anyone.
