Circut Breaker Sensor

I am trying to figure out what kind of sensor I can add to a specific circuit in the panel to detect when the circuit breaker is tripped. I’ve got a rental house with pool equipment (outdoor). One of the circuits trips from time to time. So from the technical point of view, all I need is a sensor that will be either powered and reports itself as “connected” or not powered and therefore reports itself as “disconnected”. And a way to capture the “disconnected” event and trigger the notification, probably through ITTT. Any ideas whether something like that already exists?

If you’re in the USA, this should work.

That should work! Thanks!!
