Home Assistant notifications

The best way to get started with notifications for Frigate is to use the Blueprint. 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/events mqtt topic. This provides the event_id needed to fetch thumbnails/snapshots/clips 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.

Here is a simple example of a notification automation of events 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.

automation:

- alias: Notify of events

trigger:

platform: mqtt

topic: frigate/events

action:

- service: notify.mobile_app_pixel_3

data_template:

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.

automation:

- alias: Security_Frigate_Notifications

description: ""

trigger:

- platform: mqtt

topic: frigate/events

payload: new

value_template: "{{ value_json.type }}"

action:

- service: notify.mobile_app_iphone

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

tag: '{{trigger.payload_json["after"]["id"]}}'

when: '{{trigger.payload_json["after"]["start_time"]|int}}'

entity_id: camera.{{trigger.payload_json["after"]["camera"]}}

mode: single

Conditions

Conditions with the before and after values allow a high degree of customization for automations.

When a person enters a zone named yard

condition:

- "{{ trigger.payload_json['after']['label'] == 'person' }}"

- "{{ 'yard' in trigger.payload_json['after']['entered_zones'] }}"

When a person leaves a zone named yard

condition:

- "{{ trigger.payload_json['after']['label'] == 'person' }}"

- "{{ 'yard' in trigger.payload_json['before']['current_zones'] }}"

- "{{ not 'yard' in trigger.payload_json['after']['current_zones'] }}"

Notify for dogs in the front with a high top score

condition:

- "{{ trigger.payload_json['after']['label'] == 'dog' }}"

- "{{ trigger.payload_json['after']['camera'] == 'front' }}"

- "{{ trigger.payload_json['after']['top_score'] > 0.98 }}"
