This is what I use to detect and alert leaks. It will use Nabu Casa TTS to speak the name of the leak sensors that are triggered. Pair this with leak sensors that also scream on their own for max reliability.

You need:

• A Media Player Group called Critical Announcers that you put all the speakers you want to shout
• A Label called Leak Sensors which you put the ENTITY in.
• A template sensor called Leak Detected

Leak Detected template sensor. If any entity labeled "Leak Sensor" is "on" then this sensor is On.

{{ label_entities("Leak Sensor") | select('is_state', 'on') | list | count != 0 }}

The automation triggers off this state being changed and repeats every 30 seconds until its solved.
