Designed a DIN-rail KNX lighting application controller that bridges KNX TP with a DALI-2 line.

 

Receives KNX group telegrams, converts them to DALI commands, and runs scenes, schedules, daylight/occupancy logic and DT6/DT8 tunable-white control locally (no cloud dependency).

 

Hardware: STM32 MCU, KNX TP transceiver, DALI-2 master + 16V/250mA bus PSU, 10/100 Ethernet service interface, secure element, external flash and USB-C service port.
