- Activating Data Secure on a Group Address adds a per-telegram overhead (authentication and encryption) that reduces the usable application payload.9. KNX Secure · Data-Secure-Overhead
- Tunable White control (variable colour temperature, e.g. 2700 K warm to 6500 K cool) over KNX typically uses two distinct DPTs: one for the overall intensity (DPT 5.001, %) and one for the colour temperature (DPT 7.600, K).5. Lighting Control · Tunable White
- A KNX presence detector configured with a 15-minute timeout keeps the lighting on for that duration after the last detection, then automatically switches it off.5. Lighting Control · Präsenzerkennung
- A standard KNX end-of-works deliverable typically includes the .knxproj project file, printed documentation (topology, Group Address table, electrical schematics), functional-test reports, user training, and a separate .knxkeys keyring file when KNX Secure is used.13.
