Excellent Leak Detection System — Reliable and Easy to Use I purchased the Hub + 4 Leak Sensors to monitor areas in my townhouse that are prone to moisture issues—under the HVAC unit, washer/dryer, refrigerator, and in the basement. After using them, I’m extremely impressed. Here’s what stood out: 👍 Easy Setup The installation was quick and straightforward. Each sensor paired with the hub without any trouble. 📱 Convenient Remote Monitoring The app makes it simple to check all sensors from anywhere, which gives me real peace of mind when I'm not home. 🚨 Accurate Alerts and Great Sound Quality The sensors react immediately to water. I had a real incident where my heating system’s pump failed on a very cold day. The device detected the leak instantly, and the app notification prompted me to call the HVAC technician before the situation worsened. Compact but Powerful The sensors are small enough to fit into tight spaces while still delivering strong performance. Their size makes placement very flexible. Overall, this has been a fantastic investment for protecting my home. Highly recommended for anyone looking for a reliable leak detection system.

Quick/simple install - easily connected hub to WiFi and synced up sensors. Each leak sensor tripped and alerted nearly instantly when tested. Free app is very intuitive and offers many convenient features (i.e. easily rename sensors, multiple options for alert preferences, displays battery life, view alarm history). Will definitely be looking into other home monitoring options that they offer.

I cannot recommend the YoLink Water Leak Starter Kit enough. After dealing with a minor basement leak last year that went unnoticed for two days, I knew I needed a reliable detection system. I did a lot of research before settling on YoLink, and honestly, this system blows the standard Wi-Fi sensors out of the water. Here is why this kit deserves a full 5 stars: LoRa Long-Range Technology is a Game Changer: This is the main selling point. Unlike standard smart home devices that struggle to stay connected in my basement or utility closet, the LoRa (Long Range) tech punches through walls and concrete with zero issues. I have one sensor in a detached garage about 100 feet from the house, and it has full signal strength. Ridiculously Easy Setup: I am not a super technical person, but I had the Hub and all 4 sensors up and running in under 15 minutes. You just scan the QR code in the app, and it connects instantly. No fiddling with complicated Wi-Fi passwords for each individual sensor. Silent but Deadly Accurate: Note that these are the "Silent" version of Sensor 1. They don't scream at you with an onboard siren, which I actually prefer because I have pets that would be terrified by a loud alarm. Instead, the Hub handles the audio (if you want it to), and the phone notifications are instantaneous. I tested one with a wet paper towel, and my phone buzzed within 2 seconds. The App is Fantastic: The YoLink app is clean, intuitive, and lets you set up all sorts of automation. You can even configure it to send emails or texts to family members if a leak is detected while you are on vacation. The Bottom Line: For the price of a single plumbing visit, you get a Hub and four reliable sensors. If you own a home, this isn't just a gadget; it is essential insurance. Do yourself a favor and buy this before you need it!

This YoLink leak detection system has been reliable so far. The sensors are easy to set up, the battery life is excellent, and the app notifications work instantly. I also appreciate that it works with Alexa and other smart home platforms. It gives me real peace of mind knowing I'll be alerted if a leak happens, especially in my basement and laundry room. The only problem is that the hub needs to be connected via Ethernet, which limited where I could place it in my home.

Best leak sensor product ever! 👏👏👏 Received the set ontime, installation and setup was very easy, the hub connect to home WiFi quickly, sensors work perfectly. Tested water leak and the response was within 2-3 seconds. You get both SMS message and email notifications. I have several RING and Arlo cameras, none report Internet outage. But YoLink reports immediately of WiFi disconnections. Worth every penny!

i have 8 of these spread through the house. water heaters, bathrooms, washer pans, AC pans, etc. they work great and are great peace of mind. oldest ones i've had are over two years and battery's still show strong. really quick and easy setup. I like that you don't even need a hub to connect them. also very impressed with how quick they alert. within a second or two of detection i'll get a push notification, text, and an email, pretty much simultaneously. luckily i haven't needed them for antyhing major yet, but they have helped alert me to minor leaks that could have definitely been more trouble than they were if i had gone a while not knowing about them. cheap insurance. get a bunch. toss em everywhere.

Very simple product to install, great features (such as SMS notifications), works as intended. Ordered a second set as price and functionalities made it the right choice. Detected and alerted of a leak after plumber improperly tightened a P-trap under kitchen sink.
