Our base is around 2-300W - that's a few lights plus the Mac, AppleTV, routers etc. It was below 200 when I crawled into bed last night.<br /><br />This unit uses a 433MHz signal, so I have a little receiver that plugs nicely into my Arduino gear.

Disclaimer - I also sell the Fluksometer in AU, however more to promote energy conservation than profit. Also on that post some links to reducing my household energy consumption.<br /><br />Cheers,<br /><br />David, Unknownhttps://www.blogger.com/profile/13797568231314953239noreply@blogger.comtag:blogger.com,1999:blog-35901825.post-22795495474600122272010-07-05T14:18:31.878+10:002010-07-05T14:18:31.878+10:00Hi Gavin,
