Window closed

The Window closed trigger fires when a targeted window closes. Use it to restore heating after airing out a room, confirm that windows are shut before bedtime, or start an automation only after a window has stayed closed for a while.

Using this trigger from the user interface

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

To use this trigger in an automation:

1. Go to Settings > Automations & scenes.
2. Open an existing automation, or select Create automation > Create new automation.
3. In the When section, select Add trigger.
4. Select what you want to monitor. Under By target (see Targets), pick the area the window is in, like your bedroom or kitchen. You can also select a floor, a device, a specific entity, or a label.
5. From the triggers shown for that target, select Window closed.
6. Under Trigger when (see Behavior), pick Each, First, or All to control how the trigger behaves when multiple windows are targeted.
7. Under For at least, set how long the window must stay closed before the trigger fires. Leave it at zero to fire immediately.
8. Select Save.

Options in the UI

Using this trigger 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 trigger as window.closed. A basic example looks like this:

trigger: window.closed
target:
  entity_id: binary_sensor.bedroom_window

This fires when binary_sensor.bedroom_window closes.

Options in YAML

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

Targets of the trigger

This trigger requires a target. The target is the object that Home Assistant will watch. You can select 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 as a target, and Home Assistant will watch every matching window entity behind that target.

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

You can also select different target types in one trigger. For example, you can add a specific entity and an area as targets in the same trigger to monitor 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 Trigger when option controls how the trigger responds:

• Each (any in YAML, default): the trigger fires every time any one of the targeted entities transitions. For example, if you monitor three motion sensors in the living room and someone walks past sensor 1, the automation fires. When they walk past sensor 2 a moment later, it fires again. Every individual event counts.
• First (first in YAML): the trigger fires only on the first transition in the targeted group, then waits until all targeted entities have reset before it fires again. For example, if you monitor the same three motion sensors, the automation fires when the first one picks up movement (someone entered the room). The other two firing afterward are ignored, so you get one notification per “someone walked in” event instead of three.
• All (last in YAML): the trigger fires only after the last targeted entity in the group has fired, meaning all of them are now in the expected state. For example, if you monitor the lights in the living room, bedroom, and hallway, the automation fires only once all three have turned off. This is useful for scenarios like “start the robot vacuum only after every light on the floor is off,” so you know the room is truly empty.

Good to know

• The trigger only fires when a window transitions from a known, valid state. If a window comes back from being unavailable (unavailable) or having an unknown state (unknown), the trigger does not fire for that recovery.
• This trigger works with binary sensors and covers that use the window device class.
• To react when a window opens instead, use Window opened.

Try it yourself

Save the automation, then change the state of the targeted entity to watch the trigger fire on your actual entitiesAn entity represents a sensor, actor, or function in Home Assistant.

Automation: turn heating back on when bedroom window has been closed for 2 minutes

After you air out a room, it can help to wait until the window is fully closed before heating the room again.

• Trigger: Window closed
• Target: Bedroom window sensor
• Trigger when: Each
• For at least: 00:02:00
• Action: Climate: Set HVAC mode to heat

alias: "Resume bedroom heating when the window closes"
triggers:
  - trigger: window.closed
    target:
      entity_id: binary_sensor.bedroom_window
    options:
      behavior: any
      for: "00:02:00"
actions:
  - action: climate.set_hvac_mode
    target:
      entity_id: climate.bedroom
    data:
      hvac_mode: heat

Automation: lock patio door after all ground floor windows are closed

When everyone finishes airing out the house, you can wait until every ground floor window is shut before locking the patio door.

• Trigger: Window closed
• Target: Ground-floor windows label
• Trigger when: All
• For at least: 00:01:00
• Action: Lock: Lock

alias: "Lock the patio door when all ground-floor windows are closed"
triggers:
  - trigger: window.closed
    target:
      label_id: ground_floor_windows
    options:
      behavior: last
      for: "00:01:00"
actions:
  - action: lock.lock
    target:
      entity_id: lock.patio_door
