Step2: Load CSV into KNX ETS application

• Open the KNX ETS application and the project.

• Edit -> Import Group Addresses -> Select the generated CSV file.

• Voila! New group addresses are added or existing addresses got renamed.

  

Hint: The KNX ETS application will not automatically delete group addresses not contained in the CSV file anymore. A cleanup must be done manually.
