Alerting

Diglett uses two methods of alerting for now, Email and Push Notifications.

Emails

Mainly depends on mail-utlis on linux system, therefore it should be installed on your Diglett Server.

Push Notification

For now, Diglett is using only one push notification backend called SimplePush. To use it, you should install the application on your Android and insert the key in config.ini file.

Also, you can disable the push notification feature from the same file.
