On request I provided one of the Cephalopod's minions with a photo of our yes-it's-actually-smart gas meter last week, in the hope that they might be able to fix whatever database is claiming that it's not.
As yet, no progress.
This was the mechanism in which I finally demonstrated that our meter was metric (or imperial, can't remember which way around they had confused matters). Complete with a copy of that day's newspaper, in a proof-of-life sort of gig.
Given they claimed what was in the database had always been that way and it wasn't a new meter, I still wonder if the people before us were paying 3x their gas bill. Or whether it was just British Gas bluster for yet another billing fuckup.
Our smart meters just work (though oddly, on a few occasions I've peeked into the cupboard to turn on the NAS at the end of the world, the little monitor has lost its connection, despite being about 30 cm away from the meters themselves). That cupboard truly is a place where radio waves don't dare to propagate. I was disappointed, if unsurprised, to find that when rates change, they still estimate, rather than take an actual reading.
