Summary of Power Usage?

You may want to take a look at this device that connects to your home’s mains and give you a total house usage. Prices have been as low as $10-15 for these devices, so shop around or wait for a sale. (not sure why the Amazon “Robot Check” but the link still works.) As you look at the readings, you can tell when certain devices turn on such a microwave, toaster oven, high powered heater, air conditioner, etc.
