Valve is closed

The Valve is closed condition passes when a targeted valve entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more] is currently closed.

Use it when you want an automation to continue only if no fluid is flowing through a valve. For example, create an automation to confirm that the main water shutoff is closed before performing maintenance, gate a leak-response action on whether the supply valve has been shut off, or prevent a heating system from firing while a gas valve is closed.

Using this condition from the user interface

If you prefer building automations visually, Home Assistant walks you through this condition step by step. You pick what to check, tweak a few options, and save. No YAML knowledge required.

To use this condition in an automation:

1. Go to Settings > Automations & scenes.
2. Open an existing automation, or select Create automation > Create new automation.
3. In the And if section, select Add condition.
4. Select what you want to check. Under By target, pick the area the valve is in, like your garden or utility room. You can also select a floor, a device, a specific entity, or a label, as described in Targets.
5. From the conditions shown for that target, select Valve is closed.
6. Under Condition passes if, pick Any or All to control how the check behaves when multiple valves are targeted, as described in Behavior.
7. Under For at least, set how long the valve must have been closed before the condition passes. Leave it at zero to pass immediately.
8. Select Save.

Options in the UI

Using this condition in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this condition as valve.is_closed. A basic example looks like this:

condition: valve.is_closed
target:
  entity_id: valve.garden_irrigation

This passes when valve.garden_irrigation is currently closed.

Options in YAML

YAML sometimes provides additional options for more complex use cases that are not available through the UI.

Targets of the condition

This condition requires a target. The target is the object that Home Assistant will check. You can point the condition at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will evaluate every matching valve entity behind that target.

• Entity: one specific valve entity, such as valve.living_room.
• Device: every valve entity that belongs to a device.
• Area: every valve entity in a room or area.
• Floor: every valve entity on a floor.
• Label: every valve entity that shares a label.

You can also select different target types in one condition. For example, you can add a specific entity and an area as targets in the same condition to check both of them at once.

Behavior with multiple targets

When you target more than one entity (or select an area, floor, or label that contains several), the Condition passes if option controls how the results combine:

• Any (default): the condition passes if at least one of the targeted entities matches. For example, if you check three smoke sensors and only one of them detects smoke, the condition still passes. This is useful for questions like “is there smoke anywhere in the house?”
• All: the condition passes only when every targeted entity matches. For example, if you check the same three smoke sensors, the condition passes only once all three report cleared. This is useful for “is the entire house safe now?” checks, so your automation does not send an all-clear while one room still has a reading.

Good to know

• Valves in the transitional Closing state do not satisfy this condition. The condition only passes once the valve is fully Closed. You can check the available states in The state of a valve entity.
• Valves reporting position (0 to 100%) are considered closed only when their position is exactly 0. A valve at position 1% is considered open.
• Valves that have an Unavailable or Unknown state do not count as closed. Home Assistant skips them and evaluates the condition using the remaining targeted valves.
• This condition works with any valve entity in Home Assistant, including water, gas, and air valves from integrations such as MQTT, Z-Wave, Zigbee, and ESPHome.
• Use the For at least option when you need confidence that a valve is stably closed. For example, set up an automation that waits 10 seconds before sending an “all clear” notification, to avoid false positives from a brief closure during valve movement.

More examples

Real scenarios where this condition gates an automation. Copy any example and adapt it to your setup.

Automation: confirm the main water valve is closed before sending an all-clear after a leak alert

A safety automation that waits until the main water supply valve is confirmed closed before notifying the household that it is safe to proceed. It avoids premature reassurance while water may still be flowing.

• Trigger: Time pattern: every minute
• Condition: Valve is closed
  • Target: valve.main_water_supply
  • For at least: 00:00:30
• Action: Send a notification message
  • Target: My Device (notify.my_device)

alias: "Send all-clear once main water valve is confirmed closed"
triggers:
  - trigger: time_pattern
    minutes: "/1"
conditions:
  - condition: valve.is_closed
    target:
      entity_id: valve.main_water_supply
    options:
      for: "00:00:30"
actions:
  - action: notify.send_message
    target:
      entity_id: notify.my_device
    data:
      title: "Water supply closed"
      message: >
        The main water supply valve has been confirmed closed for at least
        30 seconds. It is safe to inspect the leak and reopen when ready.

Automation: prevent the heating system from starting while the gas valve is closed

A resource-preservation automation that blocks the boiler from starting if the gas supply valve is closed. It avoids wasted ignition cycles and protects the boiler from dry-running while no gas is available.

• Trigger: Thermostat started heating
• Condition: Valve is closed
  • Target: valve.gas_supply
• Action: Turn off switch
  • Target: Boiler
• Action: Send a notification message
  • Target: My Device (notify.my_device)

alias: "Block boiler start when gas supply valve is closed"
triggers:
  - trigger: state
    entity_id: switch.boiler
    to: "on"
conditions:
  - condition: valve.is_closed
    target:
      entity_id: valve.gas_supply
actions:
  - action: switch.turn_off
    target:
      entity_id: switch.boiler
  - action: notify.send_message
    target:
      entity_id: notify.my_device
    data:
      title: "Boiler blocked"
      message: >
        The boiler tried to start but the gas supply valve is closed.
        Open the gas valve before restarting the heating system.
