We had some fun with economy 7 with a flat that in the end we never got converted to smart meter.
It seems that the modern way is to have time varying rates, but only one set of meter tails,. so in effect the whole shebang is on cheap rate at the appropriate time and full rate the rest of the time but no power is switched. The meter knows how many units were used at varying the times, but how that gets back to the billing is more complex, and I was assured that there were no contacts on the meter as such to allow us to know which rate was in force.
(The old meter has two dials and a contactor inside it, so there are two lots of tails etc.)
I have since been told this is cobblers, and that meters with timed contacts to operate pilots/relays etc are certainly available, but not all energy suppliers will wire them in or enable them in software..
Maybe this householder is with the same supplier and has to set the clock manually to match the times on the tariff and risk a bit iof mis-billing if the clock drifts?
The customer's time switch has no battery back up so power cuts will put it out of true time.

According to the house owner the meter is a smart meter. It certainly looks like one but does not have any "official" Economy 7 provision that I can identify. She claims that her tariff is Economy 7.

If that's the case you should be able to press a button a few times to see different registers for the different times - I think mine has 4 (import) plus exports - but being on a normal tariff thee of the four import registers are always zero.

and have been told that you cannot buy ordinary E7 heaters anymore without additional digital controls which I do not want, is that true?

I could not easily see the meter as it is located low down at the back of a kitchen unit in the gloom. I am not very good at emptying kitchen cupboards.
