Peace of mind, delivered — from anywhere in the world
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.

Excellent products!
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 great
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
