Alarm is armed

The Alarm is armed condition passes when one or more alarm control panel entitiesAn 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] are currently armed, regardless of the arming mode. Use it to ensure automations only run when the alarm is actually set, so your motion-triggered lights stay quiet when nobody is home to see them.

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 alarm panel is in (like your hallway or entryway). You can also select a floor, a device, a specific entity, or a label.
5. From the conditions shown for that target, select Alarm is armed.
6. Under Condition passes if (see Behavior), pick Any or All to control how the check behaves when multiple alarm panels are targeted.
7. Under For at least, set how long the alarm must have been armed 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 alarm_control_panel.is_armed. A basic example looks like this:

condition: alarm_control_panel.is_armed
target:
  entity_id: alarm_control_panel.hallway

This passes when the hallway alarm panel is currently armed in any mode.

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 alarm_control_panel entity behind that target.

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

• This condition matches any arming mode, including away, home, night, vacation, and custom bypass. If you need to check a specific mode, use the dedicated condition for that mode, such as Alarm is armed away or Alarm is armed home.
• Alarm panels that are unavailable (unavailable) or have an unknown state (unknown) do not count as armed. With Any behavior, they are skipped. With All behavior, the condition fails if every targeted alarm is unavailable.
• To check the opposite state, use Alarm is disarmed.

Ready to test this? Go to Settings > Automations & scenes, open an automation, and add this condition. Trigger the automation with and without the condition met, and watch whether it continues or stops.

Automation: turn off idle appliances at midnight if the alarm is armed

At midnight, power off standby appliances like the TV and coffee maker, but only when the alarm is armed. If nobody bothered to arm the alarm, someone is probably still awake and using them.

• Trigger: Time: 00:00
• Condition: Alarm is armed
• Target: Hallway alarm panel
• Condition passes if: Any
• Action: Switch: Turn off (TV, coffee maker)
