Send a persistent notification

The Send a persistent notification action shows a notification in the Home Assistant interface. Use it for messages you want to keep visible in Home Assistant until someone dismisses them.

Persistent notifications are useful for local reminders, maintenance messages, and other information that should stay available in the notifications panel.

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 show a persistent notification from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create to start a new one.
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 Send a persistent notification.
6. In Message, enter the notification text.
7. Optional: In Title, enter a title for the notification.
8. Optional: In Data, add integration-specific data such as a notification ID.
9. Select Save.

Options in the UI

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 notify.persistent_notification. A basic example looks like this:

action: notify.persistent_notification
data:
  title: "Reminder"
  message: "Check the laundry."

This shows a notification in the Home Assistant notifications panel.

Options in YAML

Good to know

• Persistent notifications appear in the Home Assistant notifications panel, not as push notifications on a phone or browser.
• A persistent notification stays visible until someone dismisses it or another action updates or removes it.
• If you include notification_id in data, Home Assistant updates the existing notification with that ID instead of creating a new notification.
• To send a message to a notify entity, use Send a notification message.
