# Notification Channel Examples
Here are some examples on how to set up Notification channels for some services. .\
These are only examples so feel free to edit them and play with them to your hearts content. 

## Testing

If you'd like to test your Notification channel, simply open a terminal and run this command. .\
Remember to replace the placeholders with the Notification channel endpoint you get by longpressing.

`curl {Replace_with_Notification_channel_endpoint} -d "Hello world! This is a test."`

How it should look:

## SSH & Local Logins

With your favorite text editor, open `/etc/profile` as root and add the following text to the very bottom of the file. .\
Remember to replace the placeholders with the Notification channel endpoint you get by longpressing.

```
if [ -n "$SSH_CLIENT" ]; then
curl {Replace_with_Notification_channel_endpoint} -d "${USER}@$(hostname -f) has logged in via SSH." > /dev/null
else
curl {Replace_with_Notification_channel_endpoint} -d "${USER}@$(hostname -f) has logged in locally." > /dev/null
fi
```

How it should look:

## DIUN

To get notified with DIUN, you will need to create a file and mount that file to your diun docker container. .\
This example creates a file named `cmd.sh`, and mounts it at `/etc/diun/etc.sh`

With your favorite text editor, create and open `cmd.sh`, then paste this text.


```
#!/bin/sh

env > /etc/diun/output
apk add curl
if [ "${DIUN_ENTRY_STATUS}" -ne "new" ]; then
    return 0
fi
curl {Replace_with_Notification_channel_endpoint}  -d 'There is a Docker Image update available.' 
```

Afterwards, mark `cmd.sh` as executable: `chmod +x ./cmd.sh`

Finally add this to your DIUN config under `notif:`

```
  script:
    cmd: "sh"
    args:
      - '-c'
      - '/etc/diun/cmd.sh'
```

Now when DIUN runs you should get a notification that looks like this:

> Note: I'm not entirely versed in DIUN configuration and I know there is some way to let it tell you which container needs to be updated. Pull requests to fix this feature would be helpful!

## Home Assistant

To get Notifications from Home Assistant, we will be using the RESTful Notifications service built into Home Assistant.

With your favorite text editor, open your HA `configuration.yaml` and add the following text to the bottom of the file

```
rest_command:
 notify_nextpush:
   url: '{Replace_with_Notification_channel_endpoint}'
   method: post
   payload: '{{ message }}'
```

Reload your HA configuration, go to Settings > Automations & Scenes > + Creation Automation > Create new automation > Then do + Add action > Search for "RESTful Command: notify_nextpush" > Three dot menu in top right of RESTful command > Edit in YAML, and add a message that's relavent to the notification you'd like to recieve, and remember to add a When trigger.
```
service: rest_command.notify_nextpush
metadata: {}
data:
  message: Motion detected at the front door.
  ```

  How it should look:

  ## The end!
