API

• see https://avm.de/fileadmin/user_upload/Global/Service/Schnittstellen/AHA-HTTP-Interface.pdf
• see https://stackoverflow.com/tags/fritzbox/info (with Links to Implementations)

Unit tests

The unit tests can be run with:

mvn test

If you did not setup your configuration file yet the test will run against a mocked FritzBox. When the application properties are set you might want to change the test parameters according to your environment.

Configuration File

You might want to set your application properties in $HOME/.fritzbox/application.properties

fritzbox.url=http://fritz.box:443
fritzbox.username=user
fritzbox.password=secret

History

• https://github.com/WolfgangFahl/fritzbox-java-api was a fork of
• https://github.com/kaklakariada/fritzbox-java-api

and was used at BITPlan internally for a while until we got unhappy with the license and the details of the implementation. Therefore we started a new implementation "from scratch".

C# version

The code at:

• https://github.com/WolfgangFahl/fritz-csharp-api

is a starting point. It reads the same application.properties and gets a session id to work with.
