Our electric and water meters and read by people. However, 4 or 5 years ago they started carrying handheld devices that transmit the readings to a mainstream server.
Our electricity used to be that way. The handheld devices even stored information such as the gate code for my driveway gate, so the meter reader could get to my meter. That was slow, and on rare occasions the meter reader would forget to close the gate, and my dog would get out.
I don't know if the information was transmitted, or just stored and uploaded back at the Coop office.
