Create notification

The Create notification action shows a persistent notification in the Home Assistant frontend. The notification stays visible until someone dismisses it, which makes it useful for messages that need attention, such as a reminder or a warning from an automation.

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 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.
4. In the Then do section, select Add action.
5. From the search box, search for and select Persistent notification: Create.
6. Provide a Message and, if you want, a Title and a Notification ID.
7. Select Save.

This action does not support targets. In the UI, you are not prompted to choose an area, device, entity, or label.

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 persistent_notification.create. A basic example looks like this:

action: persistent_notification.create
data:
  message: "Your message goes here"
  title: "Custom subject"

This creates a notification with a fixed title and message.

Options in YAML

Markdown support

The message supports the Markdown formatting syntax. Some examples are:

• Headline 1: # Headline
• Headline 2: ## Headline
• Newline: \n
• Bold: **My bold text**
• Italic: *My italic text*
• Link: [Link](https://www.home-assistant.io/)
• Image: ![image](/local/my_image.jpg)

Show runtime information

To show runtime information, use a template. For example:

action: persistent_notification.create
data:
  title: >
    Thermostat is {{ state_attr('climate.thermostat', 'hvac_action') }}
  message: "Temperature {{ state_attr('climate.thermostat', 'current_temperature') }}"
