This blueprint monitors one or more water leak sensors and fires a coordinated alert the moment moisture is detected: push notifications to your phones, optional TTS playback on your speakers (only if someone is home), and a custom actions slot for anything else you want to trigger. This is based on the great work done by Bekkenes, but I modified it to support multiple leak sensors.
Everything is configured through the UI — no YAML editing required after import.
What it does
- Monitors multiple leak sensors: one automation covers your whole house
- Sends push notifications: to any Home Assistant companion app devices you select, with the triggering sensor’s friendly name in the title and message
- Critical notification toggle: bypasses Do Not Disturb on iOS (critical alert, full volume) and Android (alarm stream, high priority) with a single checkbox
- Presence-aware TTS: plays an audio warning on selected media players only if at least one resident is home; sensor name is prepended automatically
- TTS engine fallback: defaults to Nabu Casa cloud TTS but automatically falls back to the built-in
tts.google_translateif unavailable - Custom actions slot: run anything else on trigger (flash lights, close a water valve, etc.) with access to
{{ sensor_name }},{{ full_tts_message }}, and{{ is_critical }}in any template field
Required

moisture(any Z-Wave, Zigbee, or Wi-Fi leak sensor supported by HA) - Home Assistant Companion App installed on any phones you want to notify
