Water Leak Sensor 4 with 105dB Audio Alarm 3-Pack, SMS/Text, Email & Push Notifications, Freeze Warning, LoRa Up to 1/4 Mile Open-Air Range, w/Alexa, IFTTT, Hub Required! - desertcart.com

Review: Quickly notified us of a leak, preventing a flood in our guesthouse - Set up was super simple and the sensors work great. The Yolink notified me of a water leak in my guest house (by text) when the water heater failed and we were able to shut off the water main before any damage was done. Hub is in the main house, so I am impressed with the range of these sensors. Excellent value for the peace of mind these little devices provide. Great product!
Review: It Works Fast! Easy Setup and Good for Peace of Mind - Within the first week, I heard beeping coming from under the kitchen sink, and low and behold, we had a small leak under our sink! It really gave me peace of mind that this will keep us from suffering a costly home repair, or major damage when we might be away from the house. I would recommend! Setup was super easy and took very little time. The beeping wasn't overly loud, but loud enough to hear from several rooms away, and the app will also send an alert.

## Features
