Another point to save, if your computers are running 24/7 and mainly
Took the time to write a script to tally up usage for a whole month,
corresponding to the meter read dates. Without real calibration, I
was under by about 12% but it's close enough to get interesting data.
I've got a kill-a-watt meter showing up on Tuesday so maybe I'll
calibrate it more

Really interesting and surprising?
I am sure that you build a really fine powermeter.
But my feeling is, that power meters are not really useful for smart
people. I

Some things *were* surprising. I originally made it because my
assumptions were *not* correct.
Conclusion: In most cases you can guess the consumption or have the

The biggest problem isn't standby or on power, but how often devices
