I have a couple of these energy monitoring plugs1, you can control the power using the app or Home Assistant, and they monitor the power usage too. I got them with a view to monitoring when the washing machine had been on and how many times I use the coffee machine. Haven't done either of those yet but I have one connected to the coffee machine and one to the Ninja. Just have not used enough energy to do anything with yet. I will buy more of these come pay day I think.
Estimated 1354 cups of coffee from my espresso machine1 probably comes to £1.17 a cup (including actual coffee and now servicing1 so not the 'leccy).
