YoLink Water Leak Starter Kit: Hub + 6 Leak Sensor 4 (105 dB Siren), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant

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.

These work great. I have so much reassurance that I’ll receive an alert if I have a leak in my home. The setup was super easy and the app is simple to use!

In my opinion this is a great system for leak detection. It was super easy to set up, and I had zero issues connecting any of the sensors. They all work throughout my house and the range is a huge plus. The app is easy to use and when I tested the sensors they immediately detected water. I would highly recommend YoLink for a leak detection system.

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.

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.

This product is just as advertised. It is easy to setup and very reliable. It only took about 15 minutes to setup up the hub and connect all 6 sensors. It gives great peace of mind while traveling and is the best deal I could find for leak detection.

The YoLink Water Leak Starter Kit (Hub + 4 Sensors) is a top-tier choice for reliable, long-range flood protection. Core Benefits Extreme Range: Uses LoRa technology to maintain a connection up to 1/4 mile away, making it perfect for basements or detached garages where Wi-Fi fails. Offline Reliability: Devices can pair directly (Control-D2D), meaning the sensors can trigger a siren or shut-off valve even if your Wi-Fi or internet goes down. Battery Life: Sensors typically last 5+ years on two AAA batteries, significantly outperforming competitors. Easy Setup: Features "Scan & Play" QR code integration via the app for near-instant pairing. Key Features Sensor 4 Upgrades: Includes a built-in 105dB alarm on the sensor itself and a freeze warning alert. Notifications: Supports push alerts, emails, and limited free SMS; integrates well with Alexa, IFTTT, and Home Assistant. Build Quality: Sensors are IP66-rated waterproof, so they continue to function even while submerged.

Buen invento

Notifications are excellent and very accurate when detecting water

1. The product description states "effortless installation" - placing the units is easy - but configuring the software installation is not. If you are at all phased by IT connectivity - try another system that is more easily installed. 2. This was delivered to the UK from the USA - so it came with a USA 2 pin plug.

I just bought them the hub with 4 sensors and an extra 3 without the hub. They are all connected I used Ethernet connection to wifi on second floor. Hub covers right to main floor and furnace room and main shutoff in basement. I cannot say how long the battery lasts as just purchased. My friend had one and he to,d me 3 years and still hasn't changed battery. No false alarms so far. I'm happy with product. Seems made of good quality.

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.
