That's clever. We also have a central smart meter in the house. It has a standard port (I believe it's called "P3") that allows you to read out usage. There's devices on the market that plug into this port, connect to your Wifi and then make it available to a mobile app. It reports total power usage in real time and gas usage with a delay of 15 mins. I would recommend anyone to do such tour of the house. You're very likely to learn a lot and be in for a shock here and there. Totally agree with you that most people are far away from a state of micro managing energy, there's big wins to be had with little sacrifices in convenience. And yes, that was the background of my question: If I'd save 210$ in electricity per month, my very first question would be why I even use that much in the first place. Could be valid reasons for it, of course.
