## Long description

Eve Door/Window sensor 10EBN9951 by Eve Systems GmbH is a compact wireless contact sensor designed to monitor the open/closed status of doors, windows and similar closures. The sensor uses Bluetooth for local connectivity, is supplied by a single AA alkaline battery (3.6 V input) and comes in a discreet white housing with a 52 mm width. Its small transmitter components enable installation in tight spaces and integration into smart-home setups that support Bluetooth and Matter/Thread networking when used with a compatible hub.
Advantages
This sensor provides local, battery-powered contact detection without the need for permanent wiring, enabling flexible placement. It supports modern smart-home standards including Matter and Thread (when a compatible border router is available), which improves interoperability across platforms and responsiveness of the home network. Privacy-focused design avoids cloud registration or device tracking, and notifications and automations can be run locally through the chosen platform.
Suitable for
Monitoring residential or office doors and windows
Cabinets, safety gates or small openings where compact sensors are required
Smart-home automations tied to open/closed state (lighting, heating, security)
Key specifications
Connectivity: wireless Bluetooth; compatible with Matter and Thread ecosystems when used with a suitable hub
Power source: single AA alkaline battery (3.6 V input)
Color: white
Sensor width: 52 mm
Transmitter dimensions (depth/width): approximately 1.8 x 1.8 cm
Function: magnetic contact detection for open/closed status
How to use
Install the sensor and matching magnet on the stationary frame and the moving part (door or window) ensuring alignment within the specified gap for reliable contact detection. Pair the device via the preferred smart-home app or voice assistant platform, following on-screen steps to add a new Bluetooth accessory and, if applicable, enable Matter or Thread integration through a compatible hub. Replace the AA alkaline battery as indicated by the app or when the sensor reports low battery to maintain continuous operation.
Usage recommendations
Place the sensor where the transmitter and magnet align cleanly without obstruction and avoid mounting on metal surfaces that could interfere with the magnetic field. For Thread-enabled networks, use a compatible border router to benefit from improved responsiveness and network reliability. Check platform compatibility for advanced features (remote access, notifications and automation rules) and follow the manufacturer’s guidance for battery type and replacement intervals.
