:star2: Key Features

  • Dual-Stage Wet Actions: Trigger something immediately (like a siren) and something else if it stays wet for a while (like a push notification).
  • Dual-Stage Dry Actions: Trigger actions as soon as it’s dry, and optionally wait to confirm it stays dry.
  • Integrated Battery Monitoring: No need for separate battery automations. Get notified directly when the battery drops below your chosen threshold.
  • Parallel Execution: Uses Home Assistant’s parallel mode to ensure multiple events (leak + low battery) are handled concurrently without missing a beat.
  • Professional Logic: Includes safety checks to ensure delayed actions only run if the sensor is still in the expected state.

:bulb: Example Use Cases

  • :rotating_light: Critical Alerts:
    • Wet Immediate: Trigger a siren and flash red lights as soon as a leak is detected under the washing machine.
    • Wet Long: If the sensor stays wet for 5 minutes, send a high-priority notification to all family members.
  • :electric_plug: Automatic Shutdown:
    • Wet Immediate: Use a smart plug to instantly turn off the power to a dishwasher or water heater when moisture is sensed.
  • :white_check_mark: All Clear:
    • Dry Long: Once the area has been dried, wait for 10 minutes to confirm it’s truly clear before resetting your smart home’s “Water Leak” status.
  • :battery: Maintenance:
    • Battery Low: Receive a notification when the battery level drops below 30%, giving you plenty of time to recharge or swap.

:hammer_and_wrench: Requirements

  • IKEA KLIPPBOK (E2493) sensor connected via Matter.
  • The sensor should expose a binary_sensor with device_class: moisture.
  • (Optional) The sensor should expose a sensor with device_class: battery.

:memo: Attribution

This blueprint was inspired by the work of censay on the Home Assistant Community. This version expands on the original concept by adding integrated battery alerts, flexible action selectors, and advanced timing logic.

Update: Configuration Save Fix

Hi all,

Just released a quick update to fix a configuration issue.

What changed:

  • You can now leave optional inputs completely blank.

  • Fixed the error: “Message malformed: Entity ID none is an invalid entity ID” when trying to save without selecting every single sensor.

If you had trouble saving new automations before, simply re-import the blueprint and it will work perfectly now! :white_check_mark:

I’ve just updated this blueprint to include the Active Hours feature. You can now restrict the automation to specific times of the day (e.g., motion lights only at night, or door alerts only during work hours).

Check the latest version in the repository Details in README! :rocket:
