Please reach out to Biamp support in case you need a KNX license for your project.
Once your KNX license is added to your company account, the KNX license can then get used by any employee in your organization.
The way to use the license is to drag in any KNX IP interface in system and create all your sequences and add them as functions on your buttons.
After you have completed your project, simply upload it to the controller and one license key will be deducted from your company account in the upload process.
The license follows the hardware and cannot be transferred to another Impera controller.
NOTE: Remember to be logged in, inside Project Designer, or else we can't see the licenses you've bought.
