The MQTT notification support is different than the other [notification](/integrations/notify/) platforms. It is a service.
|
||||
|
||||
## Use the the MQTT notify platform
|
||||
|
||||
The [MQTT notify service platform](/integrations/notify.mqtt/) allows you to use [MQTT discovery](/docs/mqtt/discovery/), or manual setup through `configuration.yaml` to enable a custom MQTT notify service. The notify platform helps to implement notification services on IoT notification screens, notification gateways, or for digital signage applications. An example is showing a text alert message on a climate control unit, e.g. an error, alert or informal message. The device can advertize the notification message service through discovery.
|
||||
|
||||
## Direct publishing
|
||||
|
||||
You can also publish directly, this means that you don't have to create a configuration entry but you need to provide more details when calling the service.

**Call Service** section from **Developer Tools** -> **Services** allows you to send MQTT messages. Choose *mqtt.publish* from the list of **Available services:** and enter something like the sample below into the **Service Data** field and hit **CALL SERVICE**.

The `mqtt` notify service uses MQTT to notify targets.
|
||||
|
||||
## Configuration
|
||||
|
||||
MQTT notify services are supported through [MQTT discovery](/docs/mqtt/discovery/), and manual setup through `configuration.yaml`.
|
||||
The discovery topic needs to be: `<discovery_prefix>/notify/[<node_id>/]<object_id>/config`. This integration does not create entities like other `mqtt` platforms, it will register a notify service. A `device` context is only supported through MQTT discovery. The device will automatically be created, updated and removed following discovery updates. If a discovered device is removed from Home Assistant the corresponding service will be removed as well.
|
||||
|
||||
As alternative you can also choose to [publish notifications directly](/examples/notify.mqtt).

## Examples

|
||||
In this section, you will find some real-life examples of how to use the notify service.
|
||||
|
||||
### Full configuration
|
||||
|
||||
The example below shows a full configuration for a MQTT notify service. The example will register a service `notify.intrusion_text_notification`, `notify.intrusion_text_notification_panel1` and `notify.intrusion_text_notification_panel2` that will publish at topic `home/alarm/notify/message`.

|
||||
command_template: "{{ title }}: {{ message }}"
|
