I saw them selling that information on their website the other day. I was searching for these X10 codes before Dave Houston kindly re-posted his excellent Codegen program (ta muchly), and I asked the owner of the site if he had any information on the X10 codes for the Pronto. Although I didn't buy my RU950 from him I DID buy all my X10 stuff from there. He refused to help, and said he didn't think X10 could be done without an IR converter. I KNEW he was wrong (and told him so), but he didn't care and was promoting his IR stuff to any other customer that needed a solution. When I saw him SELLING an otherwise free set of codes it put it all into perspective.
There are cheaper X10 suppliers out there in the UK,
www.letsautomate.com for a start, and you can save enough to buy the base station as well if you get the RU950 from
www.unbeatable.co.ukHope this helps.
