Presence Publisher

This free open-source app regularly publishes to a configurable MQTT topic whenever

connected to a given Wi-Fi network or in proximity to a Bluetooth beacon.

It can be used to integrate the presence of your phone in home automation.

The app uses the built-in Android alarm manager, so notifications are sent

even if the phone is in stand-by. In addition to regularly scheduled checks,

the app also reacts to changes in the network connection.

The MQTT client supports anonymous and username / password authentication

as well as client certificate authentication. For more details on how to

configure certificate-based authentication, please have a look at

https://github.com/ostrya/PresencePublisher/blob/master/README.md.
