> How will a mobile phone stuck to a meter know what sort of fridge you've got (which doesn't terrify me, anyway, to be honest) unless you've got a mobile phone stuck to your fridge as well?
There are various characteristics to how a motors starts up and stops, so you could conceivably identify specific compressor motors, if not fridges. Then looking at the duty cycle of the motor tells you a bit more. I honestly can't see anyone bother to build an database of fridge characteristics however. Someone profiling my fridge doesn't bother me.
I've no doubt the intelligence services are salivating at the information they'll get from this additional insight into the various people they keep tabs on. Real time information on when they come into a house or leave it, regardless of CCTV coverage in the area. When a computer turns on or off, when they're in the shower etc. If you're profiling potential terrorists, a sudden change in daily routine could be significant?
Having some crim use a back door into the meter or the central system to profile when the house is empty worries me more. Instead of having to steak out one house for weeks at a time, an enterprising crim could profile an entire city in a few minutes. That bothers me a bit.
Having some crim be able to shut down my meter worries me a lot more. Even that is nothing compared to what happens if they do this to a whole city, and revoke the encryption keys form the meters, or brick the firmware. Just imagine the power going out across a city of 1,000,000 people, and the only ways to fix it are to replace the meters or to illegally bypass them (lots of fires then). Yet another reason not to get a Saniflow for the toilet.
Hopefully by the time I have no choice in the matter, I'll have an independent renewable/battery system to go with my normal low energy usage, and the smart meter will feed nothing but a slow charger onto the battery bank with a little micro controller randomising the timing...
