Mi Door and Window Sensor 2 – Smart Home Security & Automation with Light Sensor

The Mi Door and Window Sensor 2 is a crucial component for building a smarter and more secure home. This compact and versatile sensor from Xiaomi provides real-time monitoring of doors, windows, drawers, cabinets, or even pet gates, offering enhanced peace of mind and enabling intelligent automation within your home.

The core functionality of the sensor relies on a magnetic induction system. When the two parts of the sensor (the main body and the magnet) are separated by more than 18mm (the maximum installation gap), the sensor detects that a door or window has been opened. Conversely, when they are brought back together, it registers as closed.

A significant upgrade in this version is the integrated light sensor. This new feature allows the sensor to detect ambient lighting conditions. This opens up possibilities for more advanced smart scenes; for example, if the sensor detects that a door opens and the ambient light is dim, it can trigger a connected smart light to turn on automatically, creating a convenient “night-time entry” scene.

The Mi Door and Window Sensor 2 connects to your smartphone via Bluetooth 5.1 BLE (Bluetooth Low Energy). While it can directly connect to your smartphone for status viewing, its full potential is unlocked when connected to a Bluetooth gateway-enabled Xiaomi device (such as a Xiaomi Smart Home Hub or certain Xiaomi AI speakers/smart cameras). This gateway allows for remote viewing of status, receiving instant push notifications on your smartphone for unexpected openings or closures, and creating automated event histories in the Mi Home/Xiaomi Home app.

Through the Mi Home/Xiaomi Home app, you can:

• Monitor real-time open/close status.
• Receive instant alerts if a door or window is opened unexpectedly (e.g., for security or if a child is on the move).
• Set alerts for doors left open for a specified duration.
• Access automated event history to review past activities.
• Link with other Xiaomi smart devices to create complex automation scenarios (e.g., if a pet gate opens, a smart camera records video and sends an alert).

The sensor is incredibly compact and lightweight (34.0 x 32.7 x 14.5 mm), making it discreet and easy to install. It uses adhesive stickers for straightforward “peel, stick, and align” mounting, without damaging your furniture. It’s powered by a CR2032 button battery (installed), which provides a long battery life, often cited to last up to 2 years under normal conditions, minimizing maintenance.
