I saw that there is a possibility to upload a file but it then still shows me a gui where I can select a single entry from the project file. but I do not want to create hundreds of entries manually.

> When you currently import a large KNX Project file (\> 100 devices) only the drop…down boxes are populated with all the available registers from the projectfile. You have to re-create all the Homey devices by hand by selecting 100+ drownboxes, sometimes 3 times per device. All the devices naming and group information is lost too. This re-creation process takes weeks of work for large project files.

> The usability for Homey in professional KNX installations would be greatly improved it it was possible to create a "master" KNX device from the KNX project file. The master KNX devices creates slave devices based on the contents of the project file, names the devices , group the devices and exactly configures each devices all based on the information in the KNX project file. When the KNX master is updated with a new projectfile all linked KNX slave devices are automatically updated. The source of truth is the KNX project file
