Yes Dan, that should help for International selection when choosing hardware from other countries.
But electric voltages are only half the criteria.
My particular problem is based on the RF protocols. (As I found out later . . .
)
I found the following extract on Wikipedia under "X10";
"The radio protocol: To allow the operation of wireless keypads, remote switches, and the like, a radio protocol is also defined.
Operating at a frequency of 310 MHz in the U.S. and 433 MHz in European systems."So, be aware of what the frequencies of your locally sourced units are transmitting on, chances are you won't be able to mix and match.
