Eufy E20 Flood & Freeze Sensor

Protect your home easily and intelligently with the Eufy Entry Sensor E20. This compact door and window sensor accurately detects when a door or window is opened and immediately sends a notification to your smartphone via the Eufy app. Ideal as part of a complete smart home security system.

Thanks to its dual-sided detection, you can flexibly install the sensor on either the left or right side of a door or window. Installation is quick and easy, with no complicated settings. The handy bypass button lets you temporarily disable the sensor, so you can, for example, step outside briefly without setting off the alarm.

The E20 works in combination with a Eufy HomeBase and offers a reliable wireless connection of up to 200 meters. This allows you to place multiple sensors throughout your home without connection issues. In addition, the long battery life of up to 5 years ensures minimal maintenance.

For added security, the sensor features tamper protection and smart notifications. This means you’ll receive an immediate alert if someone tries to remove the sensor or if motion is detected near a door or window.
