Arduino Lint has suggestions for possible improvements to https://github.com/matthias-bs/BresserWeatherSensorReceiver:

Linting library in BresserWeatherSensorReceiver
INFO: No header file found matching library name (BresserWeatherSensorReceiver.h). Best practices are for primary header
      filename to match library name.

         characters.
