Best Water Leak Detector for Range
YoLink was the first to bring the advanced technology of LoRa® to the smart home market. Our water leak detectors offer the longest receiving range in the market of up to 1/4 mile range.
Superior Battery Life
Save your time and money; while other leak detectors have a battery life lasting up to 1 or 2 years before they need to be replaced, YoLink’s low-power protocol allows for long range yet low-power smart water leak detectors, giving 5+ years of battery life!
IP68 WaterProof Rating
It may come as a surprise but many water leak detectors are not waterproof! The WLS1 is waterproof with a certified IP68 rating, which offers more protection than unrated or IP65/IP66-Rated products that are ‘water-resistant’. Our rating allows you peace of mind that you can reuse your sensor even if leaks happen.

Prevent leaks/flooding damage
Be informed immediately of off-normal environmental conditions, such as water from leaks or flooding, in your home and property, before expensive repairs are required
Wireless Water Leak Detector
Our water leak detectors are wireless, compact and easy to move, no 120V outlet or additional wiring required
Battery Powered & Portable
Uses standard alkaline batteries (2 AAA batteries); no Lithium or special batteries required
Integrity Monitoring
Smart Device Integrity Monitoring (S.D.I.M) means your smart device has 24/7 monitoring for communication and device health. Should your device fail to communicate or have a device health issue, you can be instantly notified (per your alarm strategy settings).
Control-D2D
(device-to-device pairing)
YoLink Control D2D device-to-device pairing allows for your water leak detectors to be paired to sirens and smart valves and valve controllers, or other devices, without an internet connection, and without power ("No WiFi, No Internet, No Power - No Problem!").
Enjoy functionality even during a power outage. Control-D2D paired devices will perform their paired function automatically, without an internet connection, without the app, and without AC power (in the case of battery-powered or battery-backed-up devices - an internet connection is required for full functionality and for the app to work.)
One Hub
Connect to 300+ Sensors.
One hub allows you essentially unlimited sensors connectivity.
No monthly fees, complicated wiring, or difficult installation.
Unlock the full potential of a smart home with YoLink devices.
Easy D.I.Y. Installation

Let customers speak for us
Door Sensor, Indoor Door & Window Sensor, Hub Required
Bought this to remote sensor a hot tub. Very easy install. Simply connected hub to existing router with cable and plugged into wall. Opened YoLink app and it quickly found hub and set up easily. Pressed the set button on sensor to “wake up” and app quickly found the new sensor. Placed cable in hot tub and now can remotely monitor hot tub temp from anywhere and be alerted if falls outside my set range. Couldn’t have been simpler!
Great product!
YoLink FlowSmart All-in-One Smart Water Management System: 3/4" Ultrasonic Water Meter with Automated Valve Control, Real-Time Leak Detection, App-Enabled, 10-Year Battery Life
Temperature & Humidity Sensor 3-Pack, Hub Required!
This is a good item but it would be nice if they made one just like it without the dimmer function that would be good for 15 amps
They’ve already bought more sensors!
Temperature & Humidity Sensor, Hub Required!
Easy to hide and works with for closed.
Finally a more modern approach for turning on and off landscape lighting. My preference for my lights is to turn them on at dusk, run them to about 11:30 pm at night and then turn them on again in the morning at 4:30 am and keep them lighted until sunrise occurs. Previously, my landscape lighting did this with a mechanical timer and a photo sensor. Worked, but subject to periodic repair as these components would fail. With the Smart Outdoor plug I use the Automations feature in the app and precisely control the lights for both sunset and sunrise. As a bonus, I can see engergy use throughout the year.
I have a printer that I don't use very often. It is located in a different part of the house. I use my plug to turn the printer on or off remotely. I used to forget to turn the printer off and would find it day or weeks later still on. This plug makes it easy not to forget.
These sensors work great I have them under my dishwasher, my refrigerators, my ice-maker, my sinks, toilets, etc. The latest sensors go under my ice-maker and sinks. I’ve been saved by these sensors detecting leaks, from my dishwasher, my clothes washer, and my kitchen fridge. Everyone should have these.
So far so good. Bought a few sensors to add.
