I have just moved into a house which has a X10 system. Nothing fancy, just an HR12a remote, RR501 transmitter, a couple of socket modules and a couple of the xps2's.
Problem is a couple of modules have gone bad, and finding an xps2 is impossible. I have an electrician trying to find replacements. He has ordered a knockoff xps2 for $17, but I cannot seem to find, nor can he, a RR501.
Are the other transmitters OK to operate a pool filter, spa blower, backyards lights, etc.?
