We have "smart" electric meters, and they use them to charge you almost double when you need power. It's not as bad for the summer rates, but winter you pay peak rate when you get up for work, and get home for dinner.
But now they have given us "smart" water meters. I don't get the idea for that as it's easy to store water so there is no advantage to shifting the time of day you flush. They were only reading the old meter about once a year, with then just sending a post card in the post to report my own reading the rest of the year. It's battery powered and they claim it's good for 15 years. The notice about installing the meter came with a nasty note about court orders if you tried to refuse the new meter.
