Become an ETS App Developer

Who can become an ETS App Developer?

The first step for a developer to join the ETS App world is to become a member of KNX Association. Any company or individual person involved in the development of software can become an ETS App developer. Anyone who wants to provide to the KNX community his software development experience or his ideas about extending ETS functionality in order ETS to work more efficient, is welcome.

Apply for ETS App Developer Profile

When you are ready to test your ETS App, apply to KNX in order to change your status to ETS App Developer and get access to ETS App Validation Tool.

Upload & Validate your ETS App

Once your ETS App has been finalized, upload it and ask for validation in order for the App to become available in My KNX. Only validated ETS Apps can be installed and used in the ETS. That prevents from unauthorized use of your ETS Apps. However, when your ETS App is validated, you can either select to keep it ‘private’; i.e. only for your own use, or make it ‘public’, so that everybody is able to download and use it.
