Question
A KNX/DALI gateway can drive up to 64 control gear on one DALI bus from KNX commands, exposing the gear as KNX Group Objects (DPT 1.001 on/off, DPT 5.001 dimming, DPT 232.600 RGB, DPT 17.001 scene).
Answer
True
The classic commercial integration pattern uses KNX as the building backbone (general automation, scenarios, HVAC) and DALI as a dedicated per-floor or per-zone lighting bus, joined by a KNX/DALI gateway that maps between the two. Common products include the ABB DG-S/D, JUNG 2128 REG, Theben DALI Gateway and Lunatone DALI-2 KNX, priced around 400-1200 EUR per gateway (one DALI bus = up to 64 control gear).
Preparation tip
Plan one Group Object per DALI short address rather than per group — KNX visualisation tools handle 64 individual addresses far better than they handle dynamic group membership changes.
