Connectivity and compatibility7

Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	Bluetooth LEBluetooth 5.1 BLE [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	Hub optionalStatus can be viewed on a nearby smartphone over Bluetooth. Remote alerts, remote viewing and automations need a Xiaomi Bluetooth gateway or a product with a built-in Bluetooth gateway [2]

Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Not stated by the manufacturer
Works without internet — what it means Whether the device keeps working over the local network or through a hub when the internet is down. Cloud features (remote access, voice assistants) need the internet.	Not stated by the manufacturer
App — what it means The maker’s app used to set up and control the device.	Mi Home / Xiaomi Home [2]
Bluetooth version — what it means The Bluetooth version used for the remote, wireless headphones, speakers and gamepads. Newer versions hold the connection more steadily and use less power on connected devices.	5.1 (BLE) [1]

Housing and installation4

Maximum magnet gap — what it means The largest gap between sensor and magnet at installation at which the closed state is still detected reliably. It matters on doors and windows where the leaf and frame are not flush.	18 mmGap between sensor and magnet with the door/window closed must be under 18 mm; side marks are aligned [2]

Weight — what it means The device’s weight without packaging, per the maker.	Not stated by the manufacturer

Measurement and detection2

Open trigger distance — what it means How many millimetres the magnet has to move away before the sensor reports "open". The smaller the value, the earlier a slight opening — such as airing the room — is noticed.	Not stated by the manufacturer
Light sensor — what it means Some door sensors also detect the light level. This lets you, for example, switch the light on when the door opens only after dark.
