## Automation and Device Triggers
|
||||
|
||||
The Nest integration makes [device triggers](/docs/automation/trigger/#device-triggers) available to enable automation
|
||||
in Home Assistant. You should review the [Automating Home Assistant](/getting-started/automation/) getting started guide on automations or the [Automation](/docs/automation/) documentation for full details.

## Example
|
||||
|
||||
This automation will trigger when a `nest_event` event type with a type of `camera_motion` is received from the specified `device_id`.
|
||||
|
||||
```yaml
|
||||
alias: "motion alert"
|
||||
trigger:
|
||||
- platform: event
|
||||
event_type: nest_event
|
||||
event_data:
|
||||
device_id: YOUR_DEVICE_ID
|
||||
type: camera_motion
|
||||
action:
|
||||
- service: notify.mobile_app_pixel_2
|
||||
data:
|
||||
title: motion detected
|
||||
message: front door motion detected
|
||||
data:
|
||||
image: /api/camera_proxy/camera.front_door
|
||||
```
|
||||
|
||||
The action in this section uses the [Android Companion App](https://companion.home-assistant.io/docs/notifications/notifications-basic/) and the camera proxy to send a notification with a snapshot from the camera.
|
||||
|
||||
|
||||
## Media Source
|
||||
|
||||
The Nest [Media Source](/integrations/media_source) platform allows you to browse clips for recent camera events. Home Assistant is not intended to be a Network Video Recorder (NVR) platform, however, basic support for capturing recent events is supported.
|
||||
|
||||
The table above describes which devices support event image snapshots or 10-frame mp4 video clips for recent events.
|
||||
|
||||
### Media Attachments
|
||||
|
||||
The Media Source APIs can be used in [Companion App Attachments](https://companion.home-assistant.io/docs/notifications/notification-attachments) for Notifications as actions for Device Triggers above like *Doorbell Pressed*. You will need to be familiar with both the Media Sources supported for your camera, as well as the media capabilities of the companion apps.
|
||||
|
||||
* `/api/nest/event_media/DEVICE_ID/EVENT_ID`: Media for the event, which supports image snapshots (jpg) or clip previews (mp4) depending on the camera type.
|
||||
|
||||
* `/api/nest/event_media/DEVICE_ID/EVENT_ID/thumbnail`: A thumbnail preview of the media, which supports image snapshots (jpg) or clip previews (gif) depending on the camera type.
|
||||
|
||||
You can use the event payload fields `device_id` and `event_id` in an [automation](/getting-started/automation/) to send a notification from an [actions](/getting-started/automation-action/) as shown in the examples below.

||||
