@Ghost The new house has very non-smart meters, presumably unchanged since the place was built in 1989. They are "digital" only in the sense that they have digits displayed on the front…
I found images of, I think, the same models of meter. If not they are *very* close.
Hmm, I think the risk from remote-off is probably negligible (unless someone was motivated enough to hack the things and turn it off maliciously, but that also seems very unlikely, unless they did so in bulk, indiscriminately). I'd guess the benefit of a slightly under-reading meter is probably offset by the benefit of being able to see your usage in real time, have time-of-day-variable tariffs, and things like that.
yeah that’s an old school mechanical meter, and I tend to agree the risks are negligible as even malicious attacks would need to sign the command with 2 TLS certificates for the meter to acknowledge it (not that I entirely trust the opsec to keep the private keys secure).
I generally agree the advantages of a variable tariff are worth it over the under reading, but everyone’s mileage may vary there
