## Overview

The Water Leak Starter Kit combines a powerful YoLink Hub with six Leak Sensor 4 units featuring 105 dB alarms and LoRa long-range wireless technology. Designed for professional-grade water damage prevention, it offers app, SMS, and email alerts plus offline local device triggers for uninterrupted protection. Each sensor runs on two AAA batteries lasting up to 5 years, and the system scales to support over 300 devices with smart home compatibility including Alexa, IFTTT, and Home Assistant.

## Description

Protect property from water damage with a long-range, plug-and-play leak detection system. Each kit pairs a YoLink Hub with multiple leak sensors you place near common risk points such as bathrooms, kitchens, laundry rooms, water heaters, and sump areas. When water is detected, you receive app, email, and SMS/text alerts so you can act fast. Built on LoRa, YoLink reaches where Wi-Fi struggles, with up to 1/4-mile open-air range. Unlike Wi-Fi-only systems, YoLink can act even without internet: with Control-D2D, sensors can directly trigger other YoLink devices—like sirens or motorized shutoff valves—for local protection during outages. Leak Sensor 1 is a silent sensor with no built-in siren; Leak Sensor 4 adds a built-in 105 dB audible alarm. Each sensor uses two AAA batteries and delivers up to five years of typical battery life. YoLink scales from homes to smart buildings. One hub supports 300+ YoLink sensors and devices, and hub options include the standard Hub, SpeakerHub for spoken alerts, and the Cellular Hub for flexible deployments. Manage everything in one app and expand within the YoLink ecosystem, with integrations for Alexa, IFTTT, and Home Assistant.

Review: Notifications are excellent and very accurate when detecting water
Review: 1. The product description states "effortless installation" - placing the units is easy - but configuring the software installation is not. If you are at all phased by IT connectivity - try another system that is more easily installed. 2. This was delivered to the UK from the USA - so it came with a USA 2 pin plug.

*by D***N on 19 September 2025*

This is a really good, easy to use system that work terrific. I have them in my home and cabin, both for water leak detection and they have saved me twice from a water leak doing major damage. Besides the leak detection I have a water temperature monitor on my hot tub and a water depth finder at my cabins fresh water tank. I have never had any issues till recently the hub stopped working and was replaced on warranty. Thanks again.
