How widely implemented is it? I lived in Los Angeles for over a decade, lived in half a dozen places (moving between Glendale Water and Power and LADWP). A few years ago, when shopping for houses all over the LA area I would peek to see if they had smart meters, too. I've only seen a few and never lived anywhere that had them.
There may have been seasonal price changes with dumb meters, but they couldn't have done weekday/weekend without them.
Smart water meters seemed to have decent distribution. Perhaps because of the droughts?
