I miss the point of those "advantages" - so what if I know how much water my guests used? Should I run over them in the bathroom and stop them from flushing? Should I let people only come in summer, and tell them to bring their own batteries? Should I stop having guests at all? All because the smart meter told me they pee at noon? And same for my usual electricity usage. I know what I have running and I know what I should shut down, I'm living in this house right. Not like some device sneaks on me and plugs itself in when I doze off. Ok, when I become a solar producer I will probably be helped by smarted devices, but until then I'm totally missing the point.
