I think most, if not all, X-10 made devices merely react to the line
frequency and do not care whether it is 50Hz or 60Hz. It's only for the
other two phases that it has to calculate the zero crossing times. It can
only sense the phase into which it is plugged and must calculate the others.


Anyway, the fact that it operates the lamp indicates the transceiver is
sending powerline commands OK.

Other things can cause problems. Read this page for a brief introduction to
noise and signal strength issues.
