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

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!

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.

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.

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.

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.

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.
