This is an interesting article.

"In "The House that Spied on Me," Kashmir Hill outfits her home to be as
"smart" as possible and writes about the results".

“Our TV is watching us?” he asked, surprised, even though he’d been the one to connect the TV to the router surveilling us. “Wow, I forgot.”

IanMacdonald:
There is already an analysis of how an existing smart meter can tell what TV channels or DVDs you watch by noting changes in electricity consumption during bright/dark scenes and matching these to known patterns. Only works on displays with variable backlights of course.  That is without the TV being a smart appliance.

Oh my. Must we have a power line jammer too? Nice idea.

In a "perfect" world, yes, sure. However most houses don't just have the television running. There are plenty of other appliances running which will cause that kind of "fingerprint" to become invalid. Computers, fridges, lights, pumps, amps/speakers, fans, air conditioning...

There's some smart metering tech right now that is very intelligent...

I'm thinking of an article I read on one, that was developed by ex SDR(I think) guys and using techniques from that field in relation to unpicking a bunch of close RF signals, that let them detect all sorts of devices from a single mains feed into a building.

If they can unpick the tv power draw from everything else, it shouldn't be hard to then detect the station with another step.

Now I'm going to have to go find that article....
