Re: Not so smart!
Not having a smart meter, I don't know if these second terminals have been implemented!
Yes. It's called 'Economy 7' and was implemented many years ago. For kind of the reverse problem. We built a bunch of nuclear power stations that just love running at peak power 24x7 and aren't all that turn-on-and-offable. So then what to do to sink power during off-peak periods. Solution, a simple radio teleswitch, Radio 4 and a 'clunk' at 2330 when the relay turns on stuff connected to the Economy 7 spur.
Which is part of the stupidity. There's a need for load shedding and load sinking, so if there's too much power, then turning on a bunch of water or brick storage heaters is a way to use it. Instead, wind farmers get given millions in constraint payments to not dispatch power to the grid.
