RE: TweetaWatt

["Richard \(lists\)" <rich_lists@xxxxxxxxxx>]

Its actually getting kVAh which from what I have seen on my measuring
devices is sometimes a huge difference from the actual power consumed and
billed for. Particually on switching power supplies.



No idea if the chip in them calculates the true watts and would be able to
get it out of it easily, but the simplistic measurement that the tweetawatt
does will be far from ideal on things like dimmed lights, horrible energy
saving lights and PCs which at least for me are where a bulk of the power
goes to.

"Using "off-the-shelf hardware", we have modified a
Kill-a-Watt(TM) power
meter to "tweet" (publish wirelessly) the daily KWH consumed to
the user's
Twitter account (Cumulative Killowatt-hours). We are releasing this project
as an "Open source hardware" project - in other words, anyone can
make
these, modify them and make a commercial product from the ideas and
methods..."
