## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent leak detection system
*by P***O on July 13, 2025*

The setup of the YoLink Water Leak Sensor 4-Pack with Hub was simple. All you need to do is download the app on your phone, create an account, and register your devices. I won’t get into how to navigate the app—it’s very intuitive. Instead, I’ll focus on a few critical points that you should keep in mind:1. You absolutely need the hub.While the app lets you register the leak sensors independently, this does not mean the hub is optional. The hub is essential because the sensors communicate with it using LoRa, a long-range, low-power wireless protocol. This technology is what gives the sensors their impressive multi-year battery life.2. Registering the hub is quick and reliable.Just power up the hub and connect it directly to your router with an Ethernet cable. This is the most reliable and straightforward way to get it online. Once connected, open the app—your hub will be automatically detected and registered. It really is that easy.3. Registering the leak sensors takes a quick button press.To add a sensor, press the on/off button once until you see a brief red light. That puts it into pairing mode so you can complete the setup in the app. Avoid repeatedly pressing the button, as that may actually turn the device off—something that might have tripped up other users.4. Extra sensors are affordable and worth it.Leaks can happen anywhere there’s plumbing: water heaters, bathrooms, kitchens, laundry areas—you name it. If you have a space where water and electricity meet, like a garage with a water line, I highly recommend placing a sensor there too. Given how inexpensive additional sensors are, it’s a small investment for big peace of mind.The devices themselves feel solid and well-made, with no loose wires or flimsy parts. As for long-term reliability, time will tell—though hopefully I never have to find out just how well they perform under an actual leak scenario.

### ⭐⭐⭐⭐⭐ Worth it : Yolink Temp, Humidity and Leak Sensors - A Detailed Review !
*by D***A on July 19, 2025*

Worth it : A bit pricey compared to others, and needs a cheap, small hub to operate, but Yolink is definitely worth the price, if accuracy is your goal. Leak sensors work perfectly. But bought this ecosystem more for their temp + humidity sensors. App comes with the ability to set exact temp and humidity alarms, which can be sent via App Notice, SMS Message (75 Free SMS Alerts Per Month) and/or Email Alerts, all of which are infinitely customizable. Setup is super quick, once you figure out how to scan the barcodes on each device with the App. Hub setup took 5 mins tops. Extremely long range, about 1-3km in urban areas. ProTip : Once temp sensors are setup. allow at least a few hours for them to stabilize. Sensor are very accurate. Six temp + humidity sensors all showed the exact same reading within 0.01% after six hours sitting next to each other, and App also allowed each sensor to be adjusted if needed. Highly recommended !

### ⭐⭐⭐⭐⭐ A Great Little Device, Works Perfectly in its Fifth Year!
*by S***R on July 4, 2025*

I Figured it was time I left a review for, since I've actually been using the YoLink leak detection device since 2021. It's worked flawlessly for me. I get emails when it goes offline because of power outages. I haven't had any leaks, but I'm confident it would let me know if I did. I've obviously tested it several times with a self started "leak" and it works perfectly, so I don't see why it wouldn't with an actual leak. I've been happy with my purchase and appreciate the peace of mind.I'm surprised to see quite a few negative reviews. I've found that all the things that matter, like easy set up, range, connectivity and sensitivity all work as advertised. I live in a two story home and the hub is upstairs and the main sensor is in the basement utility room, which is quite a distance away. I can happily report that I've had zero problems with range and connectivity. Like I said, I'm a happy camper and would definitely recommend!
