Excellent Product

Bought 2 to monitor a leak in the roof, which they did well and averted disaster. Bought 4 more for around water tank, behind dishwasher, washing machine etc.

it is impossible to use with Alexa, it does not work with Alexa as indicated in the description. I asked the support group for help, but they never answered to me. This service is just for show, in fact it is non-working. You won't hear any signal, just get a notification on your phone. A dubious and very expensive device is no different from cheap analogues.

Highly anticipated purchase, unfortunately it did not live up to the product marketing. Tried over two days to get the Hub to work on Ethernet and WiFi but would constantly dropout. Contacted Tech Support, who to be fair did what they could but in the end had to return the kit for refund

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 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.

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.

This YoLink Starter Kit has completely transformed my home security. The water sensors are incredibly sensitive and the app notifications are lightning-fast. I no longer worry about leaks or floods, and the peace of mind is priceless. The setup was a breeze, and the range is impressive. Highly recommend to anyone looking to boost their home security!

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!
