ETS6 (Engineering Tool Software 6) is the official KNX Association programming software used to configure every device in a KNX smart home — assigning group addresses, programming scene logic, setting dimming curves, and commissioning the entire system. In India, only certified KNX integrators like Techvault have access to ETS6, which is why a KNX-programmed home performs fundamentally differently from a consumer smart home setup.
