Get fancy with power metering: Flukso
 

Just installed this nifty package to measure power consumption at the mains coming into the house. Over time I think I'll be able to spot when Core i7 load testing starts :D

Which device do you need to do that ?

follow the linkie :D

ah, found it ... a Fluksometer :p

Gotta remember this for when I leave home (or maybe even earlier so I can check the power consumption in my room :-p )

if you want to measure power at wall outlet, better get a €15 power meter from your local Brico :D

I have 5 wall sockets in use atm and about 16 devices are connected to them, so a single €15 won't do (plus those aren't as fancy as a Fluksometer :-p )

and a fluksometer won't be able to measure your room's power usage ;-)

Why wouldn't it work for my room ? It's just a matter of attaching the current clamp on the cable leaving the fuse box :)

Nifty gadget, but 60 euro + vat + shipping is kinda expensive for me atm :)

yes wutske, you are correct, that should work.
@Piotke: worth the investment if it helps you reduce overall costs by being able to keep an eye on your consumption
