Home Technology

[the millster]

Hi, I was wondering if anyone knows of a site which gives information/supplies home technology stuff. The kind of computer run house where stereo, cctv, doors etc are contolled remotely. Also, I have heard about types of baths now where they self fill and to your desired temperature etc, obviously again done throught the home computer thing. Any help would be useful as I have no idea where to even start looking! Thanks.
