Hi Arnie,

Is the same step down transformer (I assume it is a 230-to-110)
driving all the X10 devices? If you are using seperate transformers
(or a mix of 230V and 110V devices some on the transformer and some
direct), you would have a problem; this is because the X10 signal cant
reliably jump from the secondary back to the primary (although these
are typically auto-transformers).

Also, the 60/50 Hz issue would come up only if you have the X10
devices spread over different phases; not if they are all on the same
one.
