We aren't looking for picture brightness altering second by second. More
from one shot to another.

Trouble is that when you don't know when the shots change,

You do, because you are monitoring all the channels.

But you don't get the total house consumption at anything
like that sort of sampling rate. You ONLY get the integrated
power and that is only sent out from the smart meter at a
MUCH lower rate and so can never be used to even allow
you to work out what is being watched on a single TV.

I've never been into analogies, they don't help with the question
of whether its actually possible to work out what someone is watching
on two TVs given the data that can be obtained from a smart meter.

The analogy is the other way round, if you can monitor the TVs,

You can't.

you can
also monitor the fridge/freezer.

Yes, that can certainly be monitored.
