Seems to me that internet controllable central heating has come of age and is now well within the reach of the non-geek (no offence intended, Mr Gabriel!); I'd certainly be very interested in being able to control my heating remotely from a smart phone etc. I'm certainly not interested in having BG round, and doubtless it could be done cheaper by someone else anyway (if not me).
Does anyone have first-hand experience of any currently available systems?
