YoLink Water Leak Sensor 2, 1/4 Mile World's Longest Range Smart Home Water Leak Sensor, Water Leak Detector with Built-in Siren Up to 105dB, Works with Alexa and IFTTT - YoLink Hub Required

Setup was easy and connecting the sensors to the base station was pretty painless. App is simple and straightforward. I've been able to connect the sensors from all parts of my house; reception has not been an issue.

I got this to monitor underneath our clothes dryer. We have 9 of the YoLink Leak Sensor 1's and have been very happy with them. This sensor senses water along it's fabric "cable". I wet a small section to test and the loud piercing siren alerted. The siren would not stop until a had completely dried the "cable" with a hair dryer. I have since turned off the siren alert from the Yolink app, since the sensor is already connected to a Bulldog shutoff valve which automatically shuts off the house water when a sensor signals a leak.

Very easy to install and really works! I have more than a handful of these under every water source throughout the house I know of too many people who’ve had a accident and paid huge bill for it. I love that not only will it alarm but will also notify you via your smart phone/email or text. A simple solution to monitoring your home whether you’re home or away.

This is an excellent wireless, long-life battery water leak sensor. Water drip anywhere on the wire causes an alarm. It has a local alarm and text and/or email alerts using the hub/cloud. It uses a LoRa network, low power, and long range. Batteries should last for several years and are AAA. So far, I am pleased with this. I placed it under the refrigerator with the wire stretched all around.

I tested the device and it alarms when wet. Make sure to place the cable parallel with the ground, it it hangs down it can trap air bubbles, causing the sensor not to work.
