@gsuberland best check they didn't replace the stopcock with a meter. That's what they do now, based on a sample of 2 on my street.
Coincidentally, they're using Octopus Energy's Kraken platform for their smart meters. It's designed to produce open data, but they won't allow us access to that usage data and "have no current plans to".
They're on LoRa 868MHz. Someone will crack it soon enough.
