I thought P/U/I were pretty much international. :) How did you find
out the cos(phi) in your measurement? Also, if the PC's power supply
is old and does not have PFC, the measurement could be further skewed
by a very non-sinusoidal input current... I think the only way to get
an accurate measurement in any case is to use one of those relatively
expensive energy meters that sample voltage and current at several
kHz.

That feature is in 1.2b1 and uses plain old IDE commands. Seems to
work well for those who have tried it so far, and it's recommended
not only for saving energy, but also to increase the MTBF. ;)
