I've been asking this question along with when can I have one for some

been to your energy company. This seems to be really counter intuitive as
if, for example you want to turn things on and off at high load times then
the thing would need to signal your appliances somehow, and I'd not want the
bunglers at EDF to be in charge of this even if it just went to them and
aback again.
The main reason why I cannot have a smart meter is because they say at
least, because economy 7 is not supported on current meters as the want to
move away from several meters. However in my view all they need to do is a
calculation on the readings in real time, after all a simple time switch at
each house is aallstorage heaters will need. Even now my normal electricity
usage at the economy hours is charged at the lower rate, not just heaters
and water. The mechanical switching from one meter to another seems archaic
and stupid but its done so the ready can just read off two readings. In an
electronic world this should be simple to do on any computer with a clock.

Our, several years old, economy 7 meter is electronic with LED
counters. It's all one meter, the built-in clock simply switches to
total-1 or total-2 according to the time of day. There is actually a
third counter which isn't used so, presumably, there are places that
have three different rates.

The third counter is the sum of the day and night rates.
