YoLink Water Leak Starter Kit: Hub + 2 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant

I’ve been very impressed with this Wi-Fi water valve system. It connects seamlessly to my phone and allows me to remotely open or close the main water supply to my house, which adds a great level of convenience and control. I paired it with a compatible water leak sensor to create a smart leak detection system. I also integrated everything with Alexa, so if a leak is detected, Alexa immediately announces an alarm both in my home and on my phone. At the same time, the system is set up so the valve automatically shuts off the water supply—even if Wi-Fi or power is down—which gives me extra peace of mind. I’ve only been using it for a few months, so I can’t yet speak to the long-term battery life of the sensors. The valve itself is connected to a 110V power source but includes a backup battery to operate during power outages, which is a great feature. Overall, I feel much more comfortable knowing my home is protected against potential water leaks. It’s a smart investment for anyone looking to prevent costly water damage

We bought the YoLink Hub + Sensor kit to monitor our attic water heater setup, including the T&P valve, cold water pipe, hot water pipe, and drain pan, as well as the water level in our basement sump area. So far it has worked very well. The biggest benefit is peace of mind. These are areas we do not check every day, so having reliable alerts makes a big difference. Setup was straightforward, the sensors connected without much trouble, and the system has been stable. Notifications have been timely, which is exactly what we wanted. If you need monitoring for places like an attic, utility area, or basement where early warning matters, this system is a great choice.

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!

Water damage is one of those home disasters you don't think about until it's too late. The YoLink Water Leak Starter Kit changed that calculus for me completely — and the relief it provides is hard to overstate. Setup was remarkably straightforward. Getting the hub and four sensors up and running required minimal effort, which matters when you're dealing with hardware that's going behind appliances and under sinks. No wrestling with complicated configurations or cryptic instructions. The real magic is what happens once it's all running. If a sensor detects a leak, it automatically triggers the main water shutoff — no intervention needed, no frantic rush home, no crossed fingers. That automatic response alone is worth the price of admission. But on top of that, I can shut off my main water supply manually from anywhere, whether I'm at the office, on vacation, or just away for the weekend. That kind of remote control over something as critical as your water supply is genuinely reassuring. The LoRa long-range connectivity means the sensors stay reliably connected even in spots where other wireless devices might struggle — basements, utility rooms, far corners of the house. And the Alexa integration works seamlessly, adding another convenient way to interact with the system without reaching for your phone. If you're a homeowner who wants to stop worrying about what might be happening to your house while you're away, this kit is a no-brainer. It's practical, it's reliable, and it delivers exactly what it promises. Absolutely worth every penny.

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.

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.

Excellent product. Easy to install easy to use and setup. Highly recommended.

Notifications are excellent and very accurate when detecting water

This is a really good, easy to use system that work terrific. I have them in my home and cabin, both for water leak detection and they have saved me twice from a water leak doing major damage. Besides the leak detection I have a water temperature monitor on my hot tub and a water depth finder at my cabins fresh water tank. I have never had any issues till recently the hub stopped working and was replaced on warranty. Thanks again.

Works terrific and I would highly recommend these for added protection alerts in your home

Easy set up with QR code scan. Works well on tests/simulated leaks.
