FAQ

How can I reduce false alarms?

Avoid placing the sensor in direct light or near heat sources. Do not place the sensor near or facing windows, heaters, fireplaces, or air vents, as these can cause false triggers. Multiple pets gathering together (weighing over 80 lb / 36 kg), or pets jumping and climbing, may trigger false alarms. Do not aim the detector at stairs, furniture, or any other objects that pets could potentially climb on. Do not install the sensor at a height lower than 6 ft (1.8 m), and ensure the sensor is vertical with the floor.

How long does the battery last?

Under normal conditions, it can last for 5 years.
Note: Data based on internal lab testing. Actual performance may vary depending on usage conditions.

Does eufy Motion Sensor E20 require a connection to HomeBase™? Which HomeBase™ models is it compatible with?

Yes, it needs to be connected to HomeBase™. Ensure your HomeBase is running the required version: HomeBase™ Mini (v4.0.5.2 or above); HomeBase™ S280 / HomeBase™ 2 (v3.4.1.2 or above); HomeBase™ S380 / HomeBase™ 3 (v3.7.2.6 or above); HomeBase™ Pro (v4.1.4.3 or above).

What is the recommended installation height and angle?

For the best detection performance, we recommend installing at a height of 6 - 7.5 ft (1.8 - 2.3 m). The sensor is more sensitive to movement passing through its field of view, so it is not recommended to place it facing the door or path directly. Instead, place it at an angle to the target detection area.

How can I turn on Pet mode? Are there any limitations?

You can turn Pet mode on or off in the app. Pet mode can reduce false alerts for pets under 80 lb. However, if pets jump onto elevated surfaces such as sofas or furniture, the sensor may misinterpret them as a human or a large animal. Additionally, if multiple pets gather closely together, the sensor might perceive them as a single large animal, which could trigger a false alarm.
