Power meter

I bought a power meter the other day from Doctor Energy - their customer communications could do with some work but it was only a tenner and turned up within about 2 weeks. It measures current, voltage and power factor, and from that derives total power consumption and cost. So the oxygen generator for Jamie uses about 400 W, the steriliser costs about 1p/day and the phone charger doesn't even register. I'll hook it up to a few different things to see what they use - I'm interested to see what the video and cable box consume when they are on standby; also my intenet gear is on all the time so must gobble up a fair amount over time.
