I think your thread title was rather goady. It isn't dumb to like your status quo and not go for a smart meter. Nor is it dumb to like a smart meter and find them useful.
I like our smart meter to be honest and really don't get all of the angst about them. Ours is supposed to be one which isn't tied in to one particular supplier, so I hope we will find that to be true.
I've always been careful with electricity usage and turned items off when not in use. I don't use the smart meter for that, but I do like the information it gives me at the touch of a button, such as how much we have spent in a day, a week, a month etc. without having to go outside and read the meter (which I used to do fairly often by the way). It is read remotely by the provider, and I like that. I am hoping it will mean and end to the inaccurate estimated readings, which various providers managed to apply to us even though we supplied them with regular readings ourselves. Time will tell on that one, but fingers crossed.
We use ours in conjunction with solar panels on the roof, and it also shows us how much we are making and exporting to the national grid, for which there is a feed-in tariff payable to us.
Obviously people who have responded on this thread are ones who are aware and conscious of their electricity usage, but there are plenty of others around who never give it any thought. Maybe smart meters would make some of those think a bit more carefully (or maybe nothing would).
I have no problem with smart meters. I imagine they are fitted as standard in new-build properties now?
Oh, and I never run the washing machine or tumble dryer overnight. Too much of a fire risk. Also, with solar panels here it is cheaper for us to run them during the day when those are producing a lot of what we need.
