Connection path The radios and ecosystems the manufacturer documents, including any hub, bridge or controller that must be bought separately. Published protocol support is a manufacturer statement, not a tested interoperability or security result. A required controller sold separately is not included.

Wi-Fi built in Whether the lock itself contains a Wi-Fi radio for remote access without a separate bridge. Wi-Fi through a separately sold bridge or hub does not satisfy this field.

Matter documented Whether the manufacturer documents Matter for this lock, directly or through a named bridge, as recorded in the note. Matter exposure through a hub still needs that hub.

Questions to check before buying	This is the shipping U400 (DL-D06E), not the CES 2026 announcement; door thickness is not published, so fit must be checked with Aqara support before purchase. Matter, Thread, UWB and Home Key support are manufacturer statements that depend on a separately sold controller; they are not tested interoperability or security results.
