Siren is off

The Siren is off condition is useful when an automation should continue only when a siren is quiet. You can use it to confirm a reset is complete, avoid starting a test during a real alarm, or make sure another action runs only after the siren has stopped.

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 siren is in. You can also select a floor, a device, a specific entity, or a label.
  5. From the conditions shown for that target, select Siren is off.
  6. Under Condition passes if (see Behavior), pick Any or All to control how the check behaves when multiple sirens are targeted.
  7. Under For at least, set how long the siren must stay off before the condition passes.
  8. Select Save.

Options in the UI

Condition passes if

When multiple sirens are targeted, controls how results combine. Pick Any to pass if at least one targeted siren is off, or All to pass only when every targeted siren is off.

For at least

How long the siren must stay off before the condition passes.

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 siren.is_off. 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: siren.is_off
target:
  entity_id: siren.entry

This passes when siren.entry is currently off.

Options in YAML

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

behavior string

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

for string

How long the siren must stay off before the condition passes. Accepts a duration string like 00:05:00.

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 siren entity behind that target.

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

  • Sirens in the unavailable or unknown state do not count as being off.
  • With All behavior, the condition passes only if every targeted siren is off for the selected time.
  • To check whether a siren is sounding, use Siren is on.

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: confirm the alarm has reset after the siren stays off

After you disarm an alarm, you may want a quick confirmation that the siren has really stopped. This automation waits for the entry siren to stay off for 30 seconds, then sends a message that the reset is complete.

  • Trigger: State changed: Home alarm to disarmed
  • Condition: Siren is off
    • Target: Entry siren
    • For at least: 00:00:30
  • Action: Send a notification message
    • Target: My Device (notify.my_device)

    data:
      title: "Alarm reset complete"
      message: >
        The entry siren has been off for
        30 seconds.

Automation: run a siren test only when every siren is off

Testing a siren is useful, but not if a real alarm is already active. This automation runs a short siren test at noon only when every targeted siren is already off.

  • Trigger: Time: 12:00
  • Condition: Siren is off
    • Target: All sirens (by label)
    • Condition passes if: All
  • Action: Turn on siren
