### Service The service `persistent_notification.create` takes in `message`, `title`, and `notification_id`. | Service data attribute | Optional | Description | | ---------------------- | -------- | ----------- | | `message` | no | Body of the notification. Accepts [templates](/topics/templating/). | `title` | yes | Title of the notification. Accepts [templates](/topics/templating/). | `notification_id` | yes | If `notification_id` is given, it will overwrite the notification if there already was a notification with that ID. Here is how an [action](/getting-started/automation-action/) of your [automation setup](/getting-started/automation/) with static content could look like. ```yaml action: service: persistent_notification.create data: message: "Your message goes here" title: "Custom subject" ``` If you want to show some runtime information, you have to use [templates](/topics/templating/). {% raw %} ```yaml action: service: persistent_notification.create data: title: > Thermostat is {{ state_attr('climate.thermostat', 'hvac_action') }} message: "Temperature {{ state_attr('climate.thermostat', 'current_temperature') }}" ``` {% endraw %} The service `persistent_notification.dismiss` requires a `notification_id`. | Service data attribute | Optional | Description | | ---------------------- | -------- | ----------- | | `notification_id` | no | the `notification_id` is required to identify the notification that should be removed. This service allows you to remove a notifications by script or automation. ```yaml action: service: persistent_notification.dismiss data: notification_id: "1234" ``` ### Markdown support The message attribute supports the [Markdown formatting syntax](https://daringfireball.net/projects/markdown/syntax). Some examples are: | Type | Message | | ---- | ------- | | Headline 1 | `# Headline` | | Headline 2 | `## Headline` | | Newline | `\n` | | Bold | `**My bold text**` | | Cursive | `*My cursive text*` | | Link | `[Link](https://home-assistant.io/)` | | Image | `![image](/local/my_image.jpg)` |
`/local/` in this context refers to the `.homeassistant/www/` folder.
