Delete notification

The Delete notification action deletes a notification from a ntfy topic.

To delete a notification, you must provide its message ID or sequence ID. The sequence ID can be specified when sending a notification.

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 use this action in an automation or 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 ntfy: Delete notification.
6. Under Targets, select the topic of the notification you want to delete (see Targets).
7. Under Sequence ID, enter the sequence ID or message ID of the notification you want to delete.
8. Select Save.

In YAML, refer to this action as ntfy.delete. A basic example looks like this:

action: ntfy.delete
target:
  entity_id: notify.mytopic
data:
  sequence_id: "motion-detected"

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 notify entity behind that target.

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