Alarm is armed night

The Alarm is armed night 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 armed in night mode. Use it to adjust how your home behaves while everyone is asleep. Hallway lights dim to a gentle glow instead of full brightness, the doorbell stops chiming through the speakers, and automations that would disturb sleep simply don’t run.

Labs

Requires the Purpose-specific triggers and conditions Labs preview feature. Enable it at Settings > System > Labs.

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 night.
  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 in this state before the condition passes. Leave it at zero to pass immediately.
  8. Select Save.

Options in the UI

Condition passes if (Required)

When multiple alarm panels are targeted, controls how results combine. Pick Any to pass if at least one targeted alarm is armed night, or All to pass only when every targeted alarm is armed night.

For at least (Required)

How long the alarm must have been armed in night mode before the condition passes. Set to zero to pass immediately.

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_night. A basic example looks like this:

ConditionConditions are an optional part of an automation that will prevent an action from firing if they are not met. [Learn more]
condition: alarm_control_panel.is_armed_night
target:
  entity_id: alarm_control_panel.hallway

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

Options in YAML

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

behavior string Required, default: any

When multiple alarm panels are targeted, controls how results combine. Accepts all or any.

for string Required, default: 00:00:00

Duration the alarm must have been armed in night mode before the condition passes. Accepts a duration string like 00:05:00 for five minutes.

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

  • Alarm panels that are unavailable (unavailable) or have an unknown state (unknown) do not count as armed night. With Any behavior, they are skipped. With All behavior, the condition fails if every targeted alarm is unavailable.
  • If you want to check whether the alarm is armed in any mode (not just night), use Alarm is armed.
  • To check the opposite state, use Alarm is disarmed.

Try it yourself

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.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.

Automation: dim the hallway nightlight when motion is detected at night

When the hallway motion sensor detects movement, turn on the hallway light at 10% brightness, but only while the alarm is armed in night mode. During the day, you want full brightness instead.

  • Trigger: State: Hallway motion sensor detects motion
  • Condition: Alarm is armed night
  • Target: Hallway alarm panel
  • Condition passes if: Any
  • Action: Light: Turn on at 10% brightness

Automation: silence the doorbell while the house is asleep

The doorbell normally announces visitors through every speaker, but nobody wants that at 2 AM. Add a night-mode check so the speakers stay silent overnight and you get a quiet phone notification instead.

  • Trigger: State: Doorbell pressed
  • Condition: Alarm is armed night
  • Action: Send a quiet phone notification (skip the speaker announcement)

Tip

AI assistants like ChatGPT or Claude can also explain conditions or suggest the right one when you describe what you want in plain language.
