The rewards for smart meters are definitely noticeable. I’m on a tariff with octopus that mean I get cheaper (edit - overnight) electric than I can almost ever remember getting. They’re ‘tracker’, ‘agile’, ‘intelligent’ (EV charging), and other smart tariffs really do make a smart meter worth getting, depending on individual circumstances of course. Also installation was very simple an unobtrusive with octopus (electric was off for 15 mins tops), and it has worked without any issues for the entire 6 months we’ve had it. Nothing to be concerned about from my perspective.
As with most probably benign things in life, it's not that I don't want them to exist, more that (to my mind, and in my experience of stuff like this, which is significant) the reward of having one is small and is outweighed by the effort of getting one installed and consistently working.
(That's if we ignore the vast expense of the design and roll out of the things, their flaky history, and unpleasantness, like remote-force-to-prepayment features)
I do notice they are starting to push the angle of SMs being able to help us move away from gas imports and help us plan for renewables line on the current TV ads, which I guess is, at best, defensible.
