YoLink’s smart home ecosystem runs on LoRa, a radio technology built for distance and reliability. This sensor’s standout feature is its 1/4-mile open-air range from the required hub, which is a game-changer for large homes, basements, or detached garages where Wi-Fi is weak or nonexistent.

In practice, this means the sensor works where others fail. It doesn’t rely on your home’s Wi-Fi network, so it stays online even during an internet outage. The 105dB built-in siren provides a local, immediate alarm, while the app sends alerts to your phone. You get a clear two-year battery life from the included AAA cells, so it’s a set-it-and-forget-it kind of device.

The requirement for a separate YoLink hub is a real consideration. It adds to the initial cost and setup. For those already invested in the YoLink system, however, this sensor is a robust and logical addition that delivers on its core promise: reliable, long-range leak detection.
