Toggle alert

Use this action to switch an alert between acknowledged and not acknowledged. If the alert is sending notifications, it’s acknowledged and stops. If it’s already acknowledged, it starts sending notifications again.

Using this action from the user interface

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

To toggle an alert from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create automation > Create new automation.
  3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
  4. In the Then do section, select Add action.
  5. From the search box, search for and select Toggle.
  6. Select what you want to control. Under By target (see Targets), select the alert. You can also select an area, a device, or a label.
  7. Select Save.

Using this action 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 action as alert.toggle. A basic example looks like this:

ActionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called *sequence*. [Learn more]
action: alert.toggle
target:
  entity_id: alert.garage_door

This toggles the alert.garage_door alert.

Targets of the action

This action requires a target. The target is the object of the action. You can point the action 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 run the action on every matching alert entity behind that target.

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

You can also select different target types in one action. For example, you can add a specific entity and an area as targets in the same action to run the action on both of them at once.

Good to know

  • An acknowledgement only lasts while the alert is active. The next time the alert starts, it sends notifications again.
  • If the alert is set up with can_acknowledge: false, toggling it to acknowledged fails with an error.

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.
