I borrowed one of those from the public library when we move in here. It was great for prioritising replacing kitchen lights and floodlights with LEDs and so on, which were a surprisingly large chunk of energy use.Somewhere in the back of a drawer is a device to measure how much electricity you are using, by a company called Owl I think. You clipped something to the mains cable with a display in the house. Got bored with watching it so put it away about 15 years ago....
Of course, now you can do it with a smartphone app if you've a smart meter.
