You can also cut people off, or shunt them onto a pay-as-you-go tariff without installing another meter

It's also another point of failure.

I have a SMETS2 meter, and appreciate the time of day billing and better feed-in metering for my PV, but I'll not be at all surprised if this is hacked one day to cut millions of people off.

What would be the motivation to cut millions of households off from power?

EDIT: do you mean the system would be hacked?

Yes, I mean hacked.

Always a danger with connected systems. I believe that smart meters have many different controls to stop this happening, including digital signatures for important updates and also break glass recovery mechanisms. Not saying it's impossible, but I'm not losing any sleep over it.

Do you need to ask? It'd be hilarious and a badge of honour from the hackers pov.

Note - I have a smets2 meter and think it's a good idea.
