A couple of months ago, I [wrote about](/easy-push-notifications-with-ntfy) how I was using a self-hosted instance of [ntfy](https://ntfy.sh) to help streamline notification pushes from a variety of sources. I closed that post with a quick look at how I had [integrated ntfy into my Home Assistant setup](/easy-push-notifications-with-ntfy/#home-assistant) for some basic notifications.
|
||||
|
||||
I've now used that immense power to enhance the notifications I get from the security cameras scattered around my house. I'm using a [Reolink NVR with 8 PoE cameras](https://reolink.com/us/product/rlk16-820d8-a/). I selected Reolink cameras specifically because I knew it was supported by Home Assistant, and for the on-device animal/person/vehicle detection which allowed for a bit of extra control over which types of motion events would trigger a notification or other action. I've been very happy with this choice, but I have found that the Reolink app itself can be a bit clunky:
|
||||
|
||||
- The app lets you send notifications on a schedule (I only want notifications from the indoor cameras during work hours when no one is home), but doesn't make it easy to override that schedule (like when it's a holiday and we're all at home anyway).
|
||||
- Push notifications don't include an image capture so when I receive a notification about a person in my backyard I have to open the app, go select the correct camera, select the Playback option, and scrub back and forth until I see whatever my camera saw.
|
||||
|
||||
I figured I could combine the excellent [Reolink integration for Home Assistant](https://www.home-assistant.io/integrations/reolink) with Home Assistant's powerful Automation platform and ntfy to get more informative notifications and more flexible alert schedules. Here's the route I took.
|
||||
|
||||
### Alert on motion detection
|
||||
{{% notice note "Ntfy Integration" %}}
|
||||
Since manually configuring ntfy in Home Assistant via the [RESTful Notifications integration](easy-push-notifications-with-ntfy/#notify-configuration), I found that a [ntfy-specific integration](https://github.com/ivanmihov/homeassistant-ntfy.sh) was available through the [Home Assistant Community Store](https://hacs.xyz/) addon. That setup is a bit more flexible so I've switched my setup to use it instead:
|
||||
```yaml
|
||||
# configuration.yaml
|
||||
notify:
|
||||
- name: ntfy
|
||||
platform: rest # [tl! --:8 collapse:8]
|
||||
method: POST_JSON
|
||||
headers:
|
||||
Authorization: !secret ntfy_token
|
||||
data:
|
||||
topic: home_assistant
|
||||
title_param_name: title
|
||||
message_param_name: message
|
||||
resource: ! secret ntfy_url
|
||||
platform: ntfy # [tl! ++:3]
|
||||
url: !secret ntfy_url
|
||||
token: !secret ntfy_token
|
||||
topic: home_assistant
|
||||
```
|
||||
{{% /notice %}}
|
||||
|
||||
The Reolink integration exposes a number of entities for each camera. For triggering a notification on motion detection, I'll be interested in the [binary sensor](https://www.home-assistant.io/integrations/binary_sensor/) entities named like `binary_sensor.$location_$type` (like `binary_sensor.backyard_person` and `binary_sensor.driveway_vehicle`).
|
||||
|
||||
So I'll craft start with a simple automation which will push out a notification whenever any of the listed cameras detect a person (or vehicle):
|
||||
```yaml
|
||||
# torchlight! {"lineNumbers": true}
|
||||
alias: Exterior Motion Alerts
|
||||
description: ""
|
||||
trigger:
|
||||
- platform: state
|
||||
entity_id:
|
||||
- binary_sensor.backyard_person
|
||||
- binary_sensor.driveway_person
|
||||
- binary_sensor.driveway_vehicle
|
||||
- binary_sensor.east_side_front_person
|
||||
- binary_sensor.east_side_rear_person
|
||||
- binary_sensor.west_side_person
|
||||
from: "off"
|
||||
to: "on"
|
||||
condition: []
|
||||
action:
|
||||
- service: notify.ntfy
|
||||
data:
|
||||
title: Motion detected!
|
||||
message: "{{ trigger.to_state.attributes.friendly_name }}"
|
||||
```
|
||||
|
||||
{{% notice tip "Templating" %}}
|
||||
That last line is taking advantage of Jinja templating and [trigger variables](https://www.home-assistant.io/docs/automation/templating/#state) so that the resulting notification displays the friendly name of whichever `binary_sensor` triggered the automation run. This way, I'll see something like "Backyard Person" instead of the entity ID listed earlier.
|
||||
{{% /notice %}}
|
||||
|
||||
### Capture a snapshot
|
||||
Each Reolink camera also exposes a `camera.$location_sub` entity which represents the video stream from the connected camera. I can add another action to the notification so that it will grab a snapshot, but I'll also need a way to match the `camera` entity to the correct `binary_sensor` entity. I can do that by adding a variable set to the bottom of the automation:
|
||||
|
||||
```yaml
|
||||
# torchlight! {"lineNumbers": true}
|
||||
alias: Exterior Motion Alerts
|
||||
description: ""
|
||||
trigger: # [tl! collapse:start]
|
||||
- platform: state
|
||||
entity_id:
|
||||
- binary_sensor.backyard_person
|
||||
- binary_sensor.driveway_person
|
||||
- binary_sensor.driveway_vehicle
|
||||
- binary_sensor.east_side_front_person
|
||||
- binary_sensor.east_side_rear_person
|
||||
- binary_sensor.west_side_person
|
||||
from: "off"
|
||||
to: "on" # [tl! collapse:end]
|
||||
condition: []
|
||||
action:
|
||||
- service: camera.snapshot # [tl! ++:start focus:start]
|
||||
target:
|
||||
entity_id: "{{ cameras[trigger.to_state.entity_id] }}"
|
||||
data:
|
||||
filename: /media/snaps/motion.jpg # [tl! ++:end focus:end]
|
||||
- service: notify.ntfy
|
||||
data:
|
||||
title: Motion detected!
|
||||
message: "{{ trigger.to_state.attributes.friendly_name }}"
|
||||
variables: # [tl! ++:start focus:start]
|
||||
cameras:
|
||||
binary_sensor.backyard_person: camera.backyard_sub
|
||||
binary_sensor.driveway_person: camera.driveway_sub
|
||||
binary_sensor.driveway_vehicle: camera.driveway_sub
|
||||
binary_sensor.east_side_front_person: camera.east_side_front_sub
|
||||
binary_sensor.east_side_rear_person: camera.east_side_rear_sub
|
||||
binary_sensor.west_side_person: camera.west_side_sub # [tl! ++:end focus:end]
|
||||
```
