## Long description

The Wireless Door/Window Sensor Eufy T89000D4 White is a compact wireless sensor designed to detect opening events on doors and windows. It notifies the paired eufy HomeBase system when a monitored entry point is opened. The sensor is intended for use with an eufy HomeBase (sold separately) and offers straightforward installation and multi-year battery life.
Advantages
The sensor provides up to a 2-year battery life from a single battery, enabling long-term monitoring without frequent battery changes. Its small and compact design allows it to fit discreetly on most door and window frames. When a forced entry is detected, the HomeBase triggers a 100-decibel siren and you receive an instant notification on your smartphone. Installation is simple: peel off the mounting tape and stick the sensor onto the desired door or window.
Suitable for
Monitoring doors at main entrances
Securing ground-floor and balcony windows
Protecting interior doors such as those to basements or garages
Key specifications

Type: Wireless door/window open sensor
Color: White
Battery life: Up to 2 years (single battery)
Compatibility: Requires eufy HomeBase (sold separately)
Siren: 100 dB alarm triggered on HomeBase
How to use
Prepare the mounting surface by cleaning and drying the door or window frame. Peel the mounting tape from the back of the sensor and press the sensor firmly onto the frame aligned with the magnet part so the two pieces are adjacent when the door or window is closed. Pair the sensor with your eufy HomeBase following the HomeBase pairing instructions. Test the sensor by opening and closing the door or window to confirm the HomeBase receives alerts and triggers the alarm if configured.
Usage recommendations
Install the sensor within the recommended alignment distance from its magnet counterpart and avoid placing it on very uneven or dirty surfaces. Replace the battery when the eufy system indicates low battery and keep the HomeBase updated to ensure timely notifications and alarm functionality.
