A tool/device you plug into socked and it emits an alarm if the power goes off? (lemmy.ml)

Come on you tool lovers out there. Has anyone heard of the device I described on the subject line? Anything close?

How is the notification sent if there's no power to the house? Presumably no internet service then either. Or is it sent by a remote service that loses contact with your home socket?

My guess: the smart plug pings a remote server every minute or whatever. If the home server stops getting pings, it sends a notification.

Could have a dying gasp capacitor which allows the unit enough time to send the message before turning off.

Doubtful because that's a lot of work and expense to implement and useless if the router and modem don't have power.

I could see such a feature if the device was designed to work over cell networks since it's not dependent on other user hardware.
