"The current field of power monitors runs the gamut, from more complex approaches that aren't simple to install to others that are so simple that they can't reveal data in real time. So I'm nearly tingling to tell you my first impressions of the WattVision electricity monitor, a prototype that succeeds in its simplicity. It does what it claims. And it does it reliably." - Paul Buchheit from Bookmarklet

We had one of these at the old FriendFeed office. It was pretty cool. - Paul Buchheit

For a second there I thought you meant Thomas. :-) - Ruchira S. Datta

Wonders how much would the sensor be after the 6 months free trial. - AJ Batac :)

Any idea how it compares to this? http://www.blackanddecker.com/Energy... - Gabe

Do you have one of the Black & Decker ones Gabe? It looks pretty neat. I assume that it only measures the total energy usage though, not individual circuits. - Robert Felty

I looked into getting one, Rob, but I haven't yet. I like that it works with my kind of meter (spinning disk). It just attaches to your house's meter so it can't measure individual circuits, although I might consider making such a thing for my house. - Gabe

Sweet. Too bad we don't have a digital electricity meter at home. I wonder how we could get one... - Meryn Stol

We have a kill-a-watt, which is nice for measuring individual appliances, but it doesn't work for hard-wired things like ceiling fixtures. - Robert Felty
