Deploy

mvn clean install 

This installs the package to your local repository

  String key = 'XXXXXXXXXXXXX' ;
  String meterRx = 'XXXXXXXXXXXXX';
  Kamstrup kamstrup = new Kamstrup(key, meterRx);
  kamstrup.packIDDRespones.toString();
  kamstrup.packageContent.toString();
  kamstrup.infoCodes.toString();
