I am unable to see the x10 signals from my isy. I can say that the isy was seeing the signals fine when I had a coupler repeater installed, which I no longer have. I was looking for the EZX10RF to resolve my lack of x10 communication. I was thinking after I posted here that if my memory is correct, the alarm system sends the x10 codes twice. Could that be an issue to the EZX10RF?
