🔌 Detect and monitor the state of an appliance based on its power consumption - V2.1.1 - Updated!

Hello everyone!

I got a power-meter (shelly-em) and hooked it up to my appartment power circuit. My washing machine cycles have a specific pattern, and look like this (the spikes on the right; the thing on the left is two AC units):

Now - I see that most people use a smart plug to track the energy usage of specific appliances. I’d like to ask if it’s possible for this automation (or others) to detect a cycle of my washing machine from the total consumption of the appartment. My guess is it should look for patterns, not absolute values in consumption.

Is anybody doing “pattern matching” on their aggregate consumption data to say if a specific appliance is running?


Bumping this question since i also like to know.
