How to use
Mount the sensor body on the stationary frame and the magnet on the moving part of the door or window, keeping the two elements aligned and within the recommended gap so that the sensor registers open and closed states. Insert the CR-123A battery according to polarity markings before pairing. Follow the eufy Security HomeBase instructions to add the sensor to your system and configure notification and alarm settings via the companion app. Test the sensor after installation to confirm reliable communication and correct event reporting.
Usage recommendations
Place the sensor on clean, dry surfaces and avoid mounting on heavily curved or uneven areas. Replace the CR-123A battery promptly when the app or base station indicates low battery. For reliable operation, install the sensor within the wireless range of the eufy HomeBase and avoid large metal obstructions between the sensor and base station. Disable the HomeBase siren if you only want silent notifications to your smartphone.
