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!
IP67 WaterProof Rating
It may come as a surprise but many water leak detectors are not waterproof! The WLS1 is waterproof with a certified IP67 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.

I used this to monitor the temp of my deep freezer where my breastmilk is stored. It gives me peace of mind knowing everything is kept fresh!

My wife's chicken raising colleague recommended Yo Link. I am delighted at how easy the setup was, how the sensors just work. The app is easy to use, even better with a recent update. Ha c ING history is helpful to see what went on overnight. I can see when heaters turned on, etc. So glad to have several for our different coops! I highly recommend this approach!
I have purchased two of these units in the past. One went bad after about a year and a half. Called Customer Service, they sent a new one free of charge, and I shipped the old one back. They have held up great overall.
My recommendation is for YoLink to design and create an OUTDOOR POWER TRANSFORMER, that is designed as a box to mount, and to plug devices into. That will ensure proper weather proofing, and maybe also add the ability to install landscape lighting with wire connections. I would really like to see this as an option soon, since I can't really use this outdoor power strip and leave it outside year-round without being protected from mother nature.
Combining the Yolink outdoor motion sensors with the in-wall switches and instant alert through the App has proven to be a very effective way to be notified of any activity around our home and property. The hardware works great and the App is so smart and flexible the ability to customize is unlimited. Thank’s Yolink!
The battery requirement terrifies me, but I have over year before I have to worry about that. Sooner or later, they will figure out how to charge a battery or supercap from the load and get rid of a replaceable battery. I have yet to find a use for the two extra buttons, but they don't seem to hurt anything.
Works great I like the extra buttons. I would like to see a three way switch model.
I started with Yolink for the leak detection and main water shut off in my house. It was by far the best solution out there. I have since added temperature and humidity sensors to various areas of my house. This was the latest addition, and it works flawlessly, even with the doors closed. Great job Yolink!!
I use a ton of their products, they are awesome.
I love these sensors. They are a great way to keep an eye on fridge and freezer temps as well as a few places I’m worried pipes might freeze in the winter. I have temperature threshold alerts setup and one even triggers a YoLink plug that runs a small heater until the temperature is raised enough to be out of freeze danger.
Easy to install and nice display. Works great.
This Dry contact door opener is a the best. I have used for a trigger to open my gates at my property. Works excellent with Liftmaster 8900 LJ jack shaft door operators. I used the lift masters operators as gate openers. Easy to install and program. Heck it was the "No Brainer” Love the product.
I already have the leak sensors and now these. They are all great and work as described.
Very easy to program to many of the devices I have such as my garage door controller and wall outlets.
