In my case, I cook when I want to eat, and I only use the oven maybe
50% of the time. I am not going to delay dinner until 10pm, this is not Argentina. When I do the laundry, I also run an extra rinse, and then remove the clothes for drying. Doing that in the middle of the night is not an option, thanks, and I don't own a robot that could do that on its own.I appreciate that 'smart' meters may well be useful for some people, I reduced my water bill by going for one. But they are not beneficial for everyone.
