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.

Let customers speak for us
Easy to setup and love the fact it notification even when you're away
It may not be the nicest looking outlet, but it works great - used in an outdoor control scenario and it works great when correctly enclosed - does not take extra space vs add on controllers)
Excellent value
Our house was built in the 60s and the water intake line is buried in a wall. I bought this valve because it required the least amount of space for covering the wall back up, somewhat simplifying the process. It has a manual shut off in case there is zero power. It takes a lot of turning of a small knob, but at least it's a back up. We kept the original valve on the house in addition. There is AC power AND battery backup, which is ideal for us. The app seems to work well, and I could operate the valve with it. I haven't tried it from outside the house, but hopefully I will never need to use it.
The plumber had no issues installing it. He had to cut out a space about 16 inches long to install the valve. Since the unit has a battery pack, if an outlet is not nearby, it can be installed later and operate with just the batteries.
The components seem well built. The mailperson dropped the package from a few feet onto our wood floor from our front door, which is a dutch door, but nothing was broken.
The app is simple, but I had difficulty finding where to add more sensors after adding one. The app could use some interface improvements. But most importantly is having the whole house shutoff valve installed in order for the property to be covered by insurance in California.
Functions well, I use it in my restaurant for equipment that might be older than I am. I can monitor everything from my cell phone while I'm at home and if I choose I can show the health dept the history of each monitor. I do wish it could be used on my laptop but for the price and function, the cell phone app is adequate

Quick and easy to set up. Tested reliable and accurate.
Bought the motion sensor to add to my collection of excellent products from yolink
The X3 Temperature & Humidity Sensors & Speaker Hub Starter Kit was extremely easy to set up and get going.
After test-driving a few Yolink sensors, I ordered threw out all my old Samsung sensors and replaced them with Yolink. The more reliable protocol, stability, and long battery life are winners. So far, I am very satisfied with the new sensors, too.
