Hello all. I could really do with some help from someone wise out there. While I was in B&Q today I noticed "remote control dimmer" adaptors for standard bayonet light fittings. I have been toying with the idea of X-10 for a while, and I even have a "lights" icon on my RC5000. Seeing a cost saving (only £24 for 2 converters), I bought the dimmers and installed them in some uplighters I have in the HC room. Everything worked fine, until I tried to teach the RC5000 the codes from the supplied remote. No joy at all! I have a horrible feeling that the system works on RF. Does that mean I'm stuffed? Are there any upgrades to the RC5000 or boxes that convert IR to RF or vice versa? Any help available would be gratefully received as I've got the RC5000 working everything else, and the supplied remote is PIG ugly. Thanks in advance, Noel.
