Smart Hub ($60 – $100; assumed exists already) – As we discussed in our smart home manifesto, all of the advanced automation require a smart hub to manage the routines and control all your systems together. We recommend SmartThings v3 hub ($300.00) for the majority users, but please see our definitive guide to smart hubs (and review of 3 best smart hubs out of 10 we reviewed)

How to set up this automation?

Section below will have step by step instructions how to set this automation routine in the most popular smart hubs like SmartThings, Home Assistant, HomeSeer and Hubitat

Please leave comments below if you have any questions, or interested in the instruction for a specific system. This will help us to better focus our effort.

3 Steps Process How To Prevent Water Leaks Using Home Assistant

Setting this automation in Home Assistant is very straightforward. Below is a simplified example using Z-wave sensors and valves.

Add Your Leak Sensors and Shut Off Valve To Home Assistant

As per the table below we recommend using Z-wave for such a crucial part of your automation. Similar to Zigbee you do not need to change anything in the configuration files to connect to the sensors and valves once your Z-wave controller connected.

Create Leak Prevention Automation Rule

The automation is very simple it has a single trigger and a single action.

- id: Leak Detection
  alias: Leak Detection
  trigger:
  - platform: state
    entity_id: binary_sensor.aeon_labs_zw100_multisensor_6_sensor
    from: 'off'
    to: 'on'
  action:
  - service: switch.turn_on
    entity_id: switch.shut_off_valve
