I had a smart gas meter and was told it relayed it's data to the electricity smart meter and since there was no power to the gas meter I concluded it must have battery. Some years back in winter the battery must have failed and the gas shut off. (Yes, I mean it). I woke up to a cold house. Checked with neighbours who did still have gas. Looked at meter, blank screen. I had now changed supplier so called them - they said call emergency. Emergency said it's not our problem call your supplier. This went back and forth a number of times until I happened to get a more sympathetic supplier call desk handler. She arranged for a supplier's fitter to visit. After a few hours he arrived and confirmed a faulty meter, but said he could only fit a manual one. And that is how it has stayed. The pitfalls of technology! Fortunately I'm not elderly and vulnerable - be forewarned.
