I’m assuming you have a sump pump and want to be alerted if it fails. A common method is to use an additional sensor to detect high water levels.
Sump pumps can run and draw power without actually pumping water… due to issues like clogs, blocked hoses, or debris in the impeller (leaves, plastic bags, rocks, etc.). To detect this, you can use a float switch, a water contact sensor, or even a moisture sensor compatible with Home Assistant.
Placement is key: position the sensor just above the normal water level when everything is working properly. That way, you’ll be notified immediately if something goes wrong.
If it’s a critical setup, you could even automate turning on a second sump pump as soon as you’re alerted.
Anyway bit of topic for this blueprint but you would use my 
State Notifications & Actions blueprint with these types of sensors.
