Could someone give me a couple of pointers on how to incorporate X-10 codes on my Pronto for my IR7243W? I've D/L an X-10 CCF that has lists of house code, unit codes and command codes, but nothing seems to work for me. I've tried aliasing to:- House code A Unit code 1 Command code ON on a single button, but nothing works. I've tried using "A" house code and the "P" house code on my IR7243W which should allow for all house code operation. I bet it's something simple I'm doing wrong but I just can't work it out. My IR7243W should operate on IR as well as RF, RF works fine but can't seem to get the pronto going on IR. Any ideas? Cheers, Mark.
