I would like to measure the consumption of my home server, "from the wall".

Can anyone suggest a good watt meter for such a purpose?

I have heard about "kill-a-watt" but it is only available for the US
market - no use for me since I need an european version.

"Watts up? PRO" does not seems to be accurate, and is very expensive.

any suggestions?

What's inaccurate about the Watts Up Pro?

The measured values (volts, amps) are accurate enough  but the
computed values (watts, PF, etc) can be way out in left field.

For example, my Pro shows my washing machine to have a PF of 0.20! I'm
not sure that's even possible.  My KAW(s) and my Fluke power analyzer
both show the PF to be 0.65 which is what I'd expect.

The Pro seems to match the other instruments down to a PF of about 0.6
or so.  Below that the indication is junk.

BTW, I have 4 KAWs.  I can string them together, one after another, to
a load and observe them all reading the same value to within a couple
of counts on the last digit.  Impressive.  Someone got the production
line trimming right.

I paid the extra money for the Watts Ups for the ability to ride
through power dips and to a lesser extent, the data logging ability.
They do indeed ride through power losses but the saved data is

There is a European version. Keep looking. It looks a lot like the US
version, with a different receptacle on the face.
