Review: Peace of Mind! - As I mentioned in my valve controller review, as a child we had old water lines burst in our home, leading to massive damage. Ever since then I have been concerned with the same thing happening in my adult home. Finally, during a Prime Day sale I discovered the YOLink leak detection system. I combined this system with the Valve Controller to set up a smart system that will shut off my home's water if any leak is detected. That system starts here with the sensors and smart hub. I have placed a sensor under each sink and toilet fixture in my house. They also make "rope" sensors which are good to use around water heaters and under dishwashers and washing machines. They all work great. They were a breeze to configure with the smart hub. I tested each one and they all alerted as expected with a loud beep and messages to my phone. I will be purchasing more of these during the next Prime Day sale for use in my rental property as well. Highly recommend!
Review: Excellent Leak Detection System — Reliable and Easy to Use - 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.

### ⭐⭐⭐⭐⭐ Great product, easy to install, great features.
*by S***O on April 28, 2026*

These are simple to install. The LoRa functionality is great -- not dependent on WiFi connectivity. I plan on getting a LoRa controlled water cutoff, so that I can have peace of mind that a water leak will not cause catastrophic damage. I highly recommend these.
