It has no DALI, 1-Wire, CAN FT or on-board analog\/digital I\/O, so the work it takes on is software: Lua scripts, schedules, scenes and protocol conversion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree modules wide.\u003c\/strong\u003e One KNX\/TP line and one RJ45 port, powered with 24 V DC from the terminals or via passive PoE.
