Lock is locked

The Lock is locked condition helps you check whether a lock is currently secure. Use it when an automation should continue only after a door has been locked, like arming an alarm or turning off devices near an entry.

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 (see Targets), pick the area your lock is in, like your front door or garage entry. You can also select a floor, a device, a specific entity, or a label.
5. From the conditions shown for that target, select Lock is locked.
6. Under Condition passes if (see Behavior), pick Any or All to control how the check behaves when multiple locks are targeted.
7. Under For at least, set how long the lock must stay locked before the condition passes.
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 lock.is_locked. A basic example looks like this:

condition: lock.is_locked
target:
  entity_id: lock.front_door

This passes when lock.front_door is currently locked.

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 lock entity behind that target.

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

• Locks in the unavailable or unknown state are ignored when Home Assistant evaluates the condition.
• Use For at least when you want to avoid acting on a short state change.
• To check whether a door is not secured, use Lock is unlocked.

Automation: arm the alarm only if all the outside door locks are locked

Before arming the house for the night, you may want one final check that every outside door is secure. This automation runs at bedtime and arms the alarm only if all targeted locks are locked.

• Trigger: Time: 23:00
• Condition: Lock is locked
• Target: Outside door locks (by label)
• Condition passes if: All
• For at least: 00:00:00
• Action: Arm alarm away

alias: "Arm the alarm only when all locks are locked"
triggers:
  - trigger: time
    at: "23:00:00"
conditions:
  - condition: lock.is_locked
    target:
      label_id: outside_locks
    options:
      behavior: all
      for: "00:00:00"
actions:
  - action: alarm_control_panel.alarm_arm_away
    target:
      entity_id: alarm_control_panel.home_alarm

Automation: turn off the porch light if the front door has been locked for 5 minutes

Once the front door has stayed locked for a while, you may not need the porch light anymore. This automation checks every evening and turns the light off after the door has remained locked for 5 minutes.

• Trigger: Time pattern: Every 5 minutes
• Condition: Lock is locked
• Target: Front door lock
• Condition passes if: Any
• For at least: 00:05:00
• Condition: Sun is below the horizon
• Action: Turn off

alias: "Turn off the porch light after the door stays locked"
triggers:
  - trigger: time_pattern
    minutes: "/5"
conditions:
  - condition: lock.is_locked
    target:
      entity_id: lock.front_door
    options:
      behavior: any
      for: "00:05:00"
  - condition: sun
    after: sunset
actions:
  - action: light.turn_off
    target:
      entity_id: light.porch
