## Overview

The YoLink Water Leak Detector leverages industrial-grade LoRa technology to deliver the longest wireless range in the smart home market—up to ¼ mile in open air. With ultra-low power consumption, it offers an impressive 2 to 10 year battery life on just 2 AAA batteries. Unlike typical WiFi sensors, it communicates securely and privately through a dedicated hub with finance-grade encryption, ensuring no exposure to internet vulnerabilities. Easy to install and ideal for hard-to-reach or WiFi-challenged areas, it sends instant alerts via app, SMS, and optional calls, empowering proactive water leak management for modern homes and remote properties.

## Description

YoLink, by YoSmart, a US corporation based in Irvine, California, is a line of wireless smart products for residential and commercial use, utilizing wireless technology initially utilized for industrial and other large-scale applications. This technology, LoRa, short for Long-Range, is unique in the smart home industry and provides you with benefits that include 2 to 10 year battery life, 1/4 mile extreme long range, superior wall and obstruction penetration, including concrete, masonry and even metal!YoLink benefits include a more secure automation network due to a centralized and encrypted internet connection, as the devices are not on the internet and they do not rely on WiFi. All communication is encrypted, and controlled by AWS servers, for finance-grade security, backups and redundancies.

Review: Works very well and detects water, notifications are excellent
Review: This device, like the other ones in the YoLink family, is exceptionally easy to put into service and well-built which gives me confidence in its reliability. I've stationed these water sensors all over the house now, having bought a bunch more. I've rigged it so that sensing a water condition (drip, spill, flood, etc.) will sound an alarm in my home office, notify me and my wife on our cell phones (by way of the app), and send me an SMS text message. I plan to get YoLink's 110dB alarm unit too, but haven't yet. Every once in a while, I test the alarm system by putting a random sensor (say, the one under the kids' bathroom sink) in a small puddle on the countertop just to reassure me that all is still operational. I really like this system! Also, the door sensors are great because it helps me keep tabs on who's filching the junk food from the basement pantry! (I pretend the door sensor is there to ensure we close the insulated door...)

## Features

- 📶 Why Worry About WiFi? YoLink devices communicate by LoRa, an industrial-grade protocol that provides up to ¼ mile open air range. Devices do NOT connect to your network or even to the internet; they communicate with the Hub. Strong signal level, obstruction penetration, no (WiFi) holes in your internet security, and fully-encrypted communications provide more than most ask for from their smart home system!
- ⏱ Set it & Forget it! Installs in seconds! The YoLink wireless Water Sensor could not be easier to install; just place near or under the equipment you wish to monitor. Suggested uses are near or under, toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, in or near sump pumps, and by any other location subject to water leaks and flooding.
- 📡 Extreme Long Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property. Low-power operation squeezes the most out of the batteries, which can last from 2 to 10 years!
- ⚠️ Requirements – Android or Apple smartphone, YoLink Hub or YoLink SpeakerHub is REQUIRED! (please search B09FSS95G9 for SpeakerHub, our new audio SpeakerHub or B07TQLKQLJ for the original Hub) and wired ethernet port (original Hub) or stable WiFi connection (SpeakerHub or original Hub) *Optional central station monitoring, and optional add-on SMS and automated calls subscriptions are available. App is always free, with 5 free texts per device, plus 5, per month.

## Questions & Answers

**Q: Is there any way to use the water leak sensor without buying an hub? I have Amazon Echo, would that work?**
A: Sorry, no. YoLink Hub is required to set up YoLink Smart Water Leak Sensor. 
You can order YoLink Smart Hub from the link https://www.amazon.com/dp/B07TQLKQLJ 
or you can order our Smart Home Security Start kit which includes this Smart Leak Sensor, Link: https://www.amazon.com/dp/B07V246GCX

**Q: Is there an audible water leak alarm without using the app? Onboard alarm?**
A: 1. For the waterproof function of the product, we do not have a sound function for YoLink Smart Water Leak Sensor;
2. We will release a YoLink Siren soon which can connect multiple YoLink water leak sensors and other YoLink safety devices,  with long distance coverage and alarm even without network connection;
3. Because of the long coverage distance of YoLink products, even if there is sound in the sensors, we still can't hear it, Alerting user's Smart Phone is more important. What's more, our YoLink Siren is even more comprehensive.
4. Reduce its own sound function, which can be waterproof and lower power consumption. The battery life of YoLink Water Leak Sensor can last for more than 5 years.

**Q: can I use to turned a switched off if it detects a tank reached a level of water?**
A: You will need a yolink outlet or a yolink wifi togle switch ( depending on the device you are wanting it to turn off ) to link the water sensor together. Then set an "if" scenario and you should be good to go.

**Q: why is there such a stark difference in battery life between water sensor 1 vs 2? version 1 is up to 5 years while version 2 only up to 2 years**
A: Water Leak Sensor 2 has a sounder. You can optionally turn off the sounder, but since that draws current from the batteries, it is factored into the battery calculations we used.  We tend to lean towards the more worse-case scenario (more frequent use, with sounder enabled) but your experience with it will vary and it could very well be closer  to 4 years than 2.
