Cool, thanks. Do the fancier kill-a-watts record prior days' use, or do you have to remember to check them each and every day?

The Hobo loggers look cool, though slightly pricey - I wonder how hard it'd be to do an open-hardware version with an Arduino microcontroller. I may have to look into that project.

I had been looking at a Minomess 130 pulse-output water meter, they seem a bit less expensive - 1 pulse per gallon is fairly coarse, but might do the trick.

Hi Marc,

I heard about an energy monitor called Obvius. Looks cost competitive, maybe cheaper if one is willing to set up one's own data interface.
