MDT
DIN-rail KNX interface for four potential-free contacts, such as wired door/window contacts or conventional push-buttons.
This product uses KNX. A compatible bridge can expose selected functions to Matter through its IP connection. The KNX device itself does not become a Matter over Thread device.
This is a KNX device, not a native Matter product. Export requires a KNX-to-Matter bridge, ETS group-address configuration and support for the chosen Matter device type. This exact device/bridge combination has not been tested. External magnetic contact is required and is not included as a sensor in this record. Contact polarity and status readback must be configured. Button-event exposure is optional and depends on the bridge and target ecosystem; Apple Home visibility is not guaranteed.
Commission the KNX installation in ETS, then configure the bridge with the required group addresses, data types and status feedback. Check the exact bridge firmware and your Matter platform. Native KNX functions, electrical ratings and Matter functions are separate specifications.
Function mapping is not a tested device–bridge pair or individual Matter certification for this KNX model. Protection functions and essential local automation should remain in the KNX installation.
These options match the product’s KNX functions to capabilities documented for a bridge. Open the bridge for its requirements and limitations.

The bridge documents these function types. Commission the required KNX command and feedback objects in ETS, then map them in the bridge. Exact model pairing has not been tested; receiving-app support must also be checked.
