Don't forget fridges, freezers, and the heating timer.

But if something is using power with all the consumer points off,
that's wrong - maybe you're sync'd with someone else's electrisave!

:-)

I just count to 12 after switching on/off stuff, take the reading twice.

I don't have so many appliances that 24 seconds each is a big deal.
