Thanks folks. I've been measuring individual circuits with the power
monitor and also the whole supply with a data logger attached to the
incoming meter. I've run this in lots of different ways with different
circuits on or off in an attempt to get an idea of electricity use.
Gradually I've found items of waste which I've been able to
eliminate.

There's still 0.5 kwh going astray midnight to 6.00am and maybe all
day too, after I've accounted for everything I know about - fridge,
security lights, clocks, central heating and various other things like
garage door on standby. I wondered if there might be a clue in the VA
reading.

So what's the stated accuracy of your new little toy then?

Are you losing watts or measurement errors ?
