The best way to get started with notifications for Frigate is to use the [Blueprint](https://community.home-assistant.io/t/frigate-mobile-app-notifications-2-0/559732). You can use the yaml generated from the Blueprint as a starting point and customize from there.
|
|
|
|
It is generally recommended to trigger notifications based on the `frigate/reviews` mqtt topic. This provides the event_id(s) needed to fetch [thumbnails/snapshots/clips](../integrations/home-assistant.md#notification-api) and other useful information to customize when and where you want to receive alerts. The data is published in the form of a change feed, which means you can reference the "previous state" of the object in the `before` section and the "current state" of the object in the `after` section. You can see an example [here](../integrations/mqtt.md#frigateevents).

Here is a simple example of a notification automation of tracked objects which will update the existing notification for each change. This means the image you see in the notification will update as Frigate finds a "better" image.
|
|
|
|
```yaml
|
|
automation:
|
|
- alias: Notify of tracked object
|
|
trigger:
|
|
platform: mqtt
|
|
topic: frigate/events
|
|
action:
|
|
- service: notify.mobile_app_pixel_3
|
|
data:
|
|
message: 'A {{trigger.payload_json["after"]["label"]}} was detected.'
|
|
data:
|
|
image: 'https://your.public.hass.address.com/api/frigate/notifications/{{trigger.payload_json["after"]["id"]}}/thumbnail.jpg?format=android'
|
|
tag: '{{trigger.payload_json["after"]["id"]}}'
|
|
when: '{{trigger.payload_json["after"]["start_time"]|int}}'
|
|
```
|
|
|
|
Note that iOS devices support live previews of cameras by adding a camera entity id to the message data.
|
|
|
|
```yaml
|
|
automation:
|
|
- alias: Security_Frigate_Notifications
|
|
description: ""
|
|
trigger:
|
|
- platform: mqtt
|
|
topic: frigate/reviews
|
|
payload: alert
|
|
value_template: "{{ value_json['after']['severity'] }}"
|
|
action:
|
|
- service: notify.mobile_app_iphone
|
|
data:
|
|
message: 'A {{trigger.payload_json["after"]["data"]["objects"] | sort | join(", ") | title}} was detected.'
|
|
data:
|
|
image: >-
|
|
https://your.public.hass.address.com/api/frigate/notifications/{{trigger.payload_json["after"]["data"]["detections"][0]}}/thumbnail.jpg
|
|
tag: '{{trigger.payload_json["after"]["id"]}}'
|
|
when: '{{trigger.payload_json["after"]["start_time"]|int}}'
|
|
entity_id: camera.{{trigger.payload_json["after"]["camera"] | replace("-","_") | lower}}
|
|
mode: single
|

```
