Review: Reliable and Comprehensive Leak Detection System! - I recently installed the YoLink Water Leak Detection Starter Kit, and it has been a fantastic addition to my home. The system is incredibly reliable, with the LoRa technology providing an impressive range of up to 1/4 mile in open air. This ensures that even the most remote areas of my home are covered. The SpeakerHub Audio/Talking Hub is a great feature, providing clear audio alerts when a leak is detected. The integration with SMS/Text, email, and push notifications means I am always informed, no matter where I am. The compatibility with Alexa, IFTTT, and Home Assistant adds a lot of convenience, allowing me to integrate the system seamlessly with my smart home setup. The installation was straightforward, and the water leak sensor is very sensitive, providing peace of mind that any leaks will be detected quickly. Overall, this starter kit offers excellent value and comprehensive protection against water damage. Highly recommended!
Review: YoLink Products are easy to use and work great! - YoLink products are great and easy to use (I've been using them for at least 8 years). I have their HUB, audible alarm, many water sensors, smart plugs, water valve operator, and garage door controllers. They all work seamlessly with their mobile app and are easy to set-up. The water sensors have saved my home from water damage at least 4-times. If you don't have water sensors in your home, it's only a matter of time before you experience a water even that will cost you a lot of money. YoLink's products will pay for themselves many times over because it avoids costly water damage. Garage operators provide peace of mind that garage is not open (plus can operate remotely if needed).

## Features

- NO WiFi WORRIES! 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 (Not included!). Long range, obstruction penetration, no reliance on WiFi, 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.
- NO WIFI, NO INTERNET, NO POWER? NO PROBLEM! Our patented Control-D2D device-to-device pairing, over our LoRa-based wireless network, allows for devices to be paired to each other, in such a way they will continue to operate, even if WiFi is flaky, the internet goes down, or the AC power goes out!
- START SMART! A YoLink hub is required for full functionality, including for the app to work, to check battery level, etc, but your hub is compatible with a growing family of smart products for home and business! Search for B0BZBYD1MK or B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B08CBTTD17 or B07TQLKQLJ for the original Hub.
- BATTERIES INCLUDED! Two replaceable AAA batteries, good for over 5 years, are included!

## 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.

### ⭐⭐⭐⭐⭐ Water Leak Detection
*by D***N on January 4, 2026*

No regrets yet. Setup was a breeze. All the sensors connected on the first try, no problem. The app's super easy to use and has way more features than I'll probably ever use. Can't say for sure how accurate the sensors are, but they haven't gone offline since I put them in. After dealing with a huge water leak before, these sensors are totally worth it for the peace of mind.
