Alert when power draw stops

Hi, I’m new to home assistant but think it’s probably the best way to achieve my goal.

How would I go about getting an alert if the power usage from an appliance stops? Ultimately I want to get it to sound a siren or the house alarm.

Thanks in advance.

power-plugs show something like ‘current_consumption’ and you could create some automation if that falls below a certain value.

Just to clarify, you want a notification (of some type) when your house has power but the device stops drawing power?
