Modified version of the Leak detection & notifier blueprint.
Actions can be chosen freely, e.g. to call a service for email notification. Also, several actions can be added. Used Low battery level detection blueprint as example for this action.

Thanks for the blueprint. Very useful. Can I suggest an exemption please. So I added 4 leak sensors. Kitchen, Bathroom, toilet and Aquarium. I have your blueprint initiating a water valve turn off cutting off mains water and notification which works perfectly.

The Aquarium leak sensor I added is non critical and need it exempt from it. I am trying to figure out how to manually edit the blueprint but not sure I am getting it since very new to Home assistant let alone YAML.

So if you are not keen on adding this, can I confirm which one would work?
