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.

Do you offer monitoring and where do I sign up?
Love these things! Easily hooks up to hub and off and running!
A great addition to my leak prevention system by YoLink. With the price of water going up what seems like daily, I find it a good investment to prevent a high bill from the water company.
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
These sensors are economical, and work flawlessly. I started with YoLink about a year ago after being introduced to Lora with Helium. These low power long-range sensors rarely need battery changes, if at all. I started with a door sensor and two motion sensors, and now have a fully integrated home-adsistant powered home with YoLink as my main sensors. To date I have purchased 20+ motion sensors, 20+ door sensors, vibration sensors, leak sensors and a water main turn off valve. While they integrate with the internet, the leak sensors communicate with each other even without Internet to stop a potential leak. I have fully entrusted my home to YoLink and have not been disappointed.
The remote performed flawlessly. I 100% recommend this remote for quick and easy on and off control of your lighting and devices. Set up is a breeze, it truly is a must have!
I use around ten different YoLink sensors and all work well. My only complaint is not being able to move and lock into position the associated icons on the app.
App is a little confusing at first but the product so far seems good.

I recently ordered 2 wall switch 2’s to replace the original Yolink wall switches that have gone bad. Out of the 6 original Yolink wall switches I purchased 5 are now dead. 1 bad switch was replaced with a regular non smart type and 2 others were reconfigured to use the Yolink wall plug outlet, which I’ve had much better luck with. This current purchase replaced 2 wall switches that could not be reconfigured. The new switches 2’s are much better built and considerably smaller and hopefully will have a longer lifespan and be more durable. The new switches were very easy to hook up and pair to the hub and the benefit of have 2 additional sub switches (1 & 2) allows for operating many different scenarios within the system. The operation light on the switch is much smaller and less obtrusive than the original Yolink switch as well. So far I’m very pleased with the wall switch 2 and I hope they will last longer than the original Yolink wall switches which all died at around the 2 year mark. Time will tell. I’ll likely be purchasing another wall switch 2 in the near future because I’m guessing the last working original Yolink wall switch will be dead very soon.

I've deployed about 20 of these in various sites, all are working fine. Very comforting to know if water is leaking - we had two disasters in the last two years.
Installation and setup were painless. Got to give yolink credit for making it so easy to set up their devices. I own several water detection devices and have been very happy with them. I plan on trying out the motion sensors
Installed three X3 Smart Temperature & Humidity Sensors in two refrigerators and a freezer, one inside the house and two in the garage. Set up couldn't have been easier; open the Yolink app, click the 'add device' button, scan the QR code on the back of the sensor and it's set up, ready to edit the name and room as you see fit and set up alerts for hi/low temperature and humidity. The data reporting in the app works very well, allowing a variety of options to see the data over a selected date/time range, etc.
And, most importantly of course, Yolink's wireless technology works through the metal walls of refrigerators and freezers as claimed.
