Hi,I'm thinking about replacing my present home automation stuff with an arduino (maybe Mega).. I have a system that works for me but it's Time.. It's been running 20+ years on the same IBM AT with a bunch of sensors and optically isolated In/Out. lotsa Pascal code. Time To Go, and Time to get On The Net!I'll be reading the mail here...(GrayerThanU)
I'm working on a network for this at present (me and a 1000 other people probably). If you're interested have a look at http://busnet.robgray.com
$17.50 is very good but still too much to dedicate to a single light switch I guess.
