KNX Secure with Thinka — Setup Guide


Before Thinka can control KNX Secure devices, it needs to be granted access to the secure group addresses  associated with these devices. Finally, the encryption keys need to be loaded into Thinka. This involved 6 discrete steps:
  1. Import the "Thinka HomeKit bridge" into your ETS Catalog once
  2. Add the "Thinka HomeKit bridge" to your ETS project
  3. Associate the secure group address with the "Thinka HomeKit bridge"
  4. Download the configuration to affected devices
  5. Export the `.knxkeys` encryption keys from ETS
  6. Import the `.knxkeys` encryption keys in Thinka

Import Thinka device into the ETS Catalog

This has to be done once, so that the ETS Catalog knows about "Thinka HomeKit bridge". Open the Catalog panel in your ETS project and click the Import button. Download the Thinka.knxprod and Import it into the Catalog.

Download the configuration to affected devices

The Topology panel shows you which devices you need to download the configuration to. This writes the Individual Address of Thinka to the authorized sender table. Otherwise, the device will ignore secure telegrams from Thinka.
