The `persistent_notification` integration can be used to show a notification on the frontend that has to be dismissed by the user.

### 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"
|
|
```
|
|
|
|
This automation example shows a notification when the Z-Wave network is starting and removes it when the network is ready.
|
|
|
|
```yaml
|
|
- alias: "Z-Wave network is starting"
|
|
trigger:
|
|
- platform: event
|
|
event_type: zwave.network_start
|
|
action:
|
|
- service: persistent_notification.create
|
|
data:
|
|
title: "Z-Wave"
|
|
message: "Z-Wave network is starting..."
|
|
notification_id: zwave
|
|
|
|
- alias: "Z-Wave network is ready"
|
|
trigger:
|
|
- platform: event
|
|
event_type: zwave.network_ready
|
|
action:
|
|
- service: persistent_notification.dismiss
|
|
data:
|
|
notification_id: zwave
|
|
```
|
|
|
|
### 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 | `` |
|
|
|
|
<div class="note">
|
|
|
|
`/local/` in this context refers to the `.homeassistant/www/` folder.
|
|
|
|
</div>
|
|
|
|
### Create a persistent notification
|
|
|
|
Choose the **Services** tab from the **Developer Tools** sidebar item, then select the `persistent_notification.create` service from the "Service" dropdown. Enter something like the sample below into the **Service Data** field and press the **CALL SERVICE** button.
|
|
|
|
```json
|
|
{
|
|
"notification_id": "1234",
|
|
"title": "Sample notification",
|
|
"message": "This is a sample text"
|
|
}
|
|
```
|
|
This will create the notification entry shown above.
