eufy Security Flood & Freeze Sensor E20, Water Leak Detector &Freeze Alarm Extended Reach with Cable, 75 dB Alarm, 5-Year Battery, Requires HomeBase 2, 3, Mini, or Pro. For Basement, Kitchen, Laundry

1. Dual Detection for Flooding and Freezing: Monitors for water leaks and freezing temperatures (below 39.2 / 4°C) to deliver comprehensive protection.
2. Extended Reach with Extension Cable: A 3.9 ft (1.2 m) cable with a slim probe reaches narrow or hidden leak-prone areas where standard sensors may not fit, such as beneath washing machines, under dishwashers, behind refrigerators, or inside tight pipe chases. It can also monitor rising water in sump pits or tanks. When connected, both the main unit and probe stay active for leak detection at two points.
3. Powerful 75 dB Local Alarm: When a leak is detected, a 75 dB alarm is activated to help quickly locate and identify the issue.
4. Long-Lasting 5-Year Battery Life: The 1,400mAh large-capacity CR123A battery lasts longer, so you don't have to replace it frequently.
5. Requires eufy HomeBase to Operate: HomeBase Mini (v4.0.5.2 or above), HomeBase 2 (v3.4.1.2 or above, released after 2021), HomeBase 3 (v3.7.2.6 or above), or HomeBase Pro (v4.1.4.3 or above) required. Ensure your HomeBase is updated to the latest version for optimal performance.

Q:How long does the battery last?

A:Under normal conditions, it can last for 5 years.

Note: Data based on internal lab testing. Actual performance may vary depending on usage conditions.

Q:How does it detect water leaks and freezing?

A:When the metal at the bottom of the sensor comes into contact with water, it triggers an alarm to help quickly locate the leak. The built-in temperature sensor will trigger a freezing alarm when the ambient temperature drops below the set threshold.

Q:What is the function of the extension cable?

A:The extension cable comes with a slim probe that can detect water leaks in narrow gaps. When suspended, it will activate the alarm when the water level reaches a certain point.
