Review: Small size, very sensitive to water and a snap to install. - This unit is very tiny and works great. It is pretty sensitive to water. It is easy to use, just pare it up with your YoLink hub and set it where you want water to be detected. It can be pared directly to a water shut-off device from YoLink if you are using it that way. We placed ours on our boat to alert us if the bilge pump fails for some reason. Our neighbor's boat sunk recently during a storm while docked because their pump failed. We don't want this to happen to us. It is a good security investment value for our piece of mind.
Review: Works perfectly - Very easy to add to existing system. Yolink devices are fantastic and app is easy to use.

## 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.

### ⭐⭐⭐⭐⭐ Great sensors for peace of mind!
*by A***R on February 19, 2026*

The sensors work great! I have 2 water leak sensors (by the refrigerator and water heater) and 2 temperature sensors in the house (1 is in the garage). The [hone app is easy to install and easy to use. The sensors are a breeze to install as well, (using the QR code for installation is the fastest). I have mine set for phone notification as well as email.
