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.

I've not yet got a smart meter but the heating has its own meters, reporting to my phone (amongst others). 19p for the last hour, resulting in 4.5kWh of heat. Oh well, it's only winter once a year!
