Peace of mind when you're not home!
I don’t usually think much about water leaks, until one nearly turned into a very expensive problem. Installing the YoLink Water Leak Sensor ended up being one of those small decisions that quietly pays for itself in a big way. I had it set up two years ago, mainly as a precaution. Last summer, we traveled abroad on vacation, so there was no one at home. I had left the main water supply on to keep the lawn irrigation running. Mid vacation, a leak started, at the worst possible time! What made the difference was the instant alert. I received a notification on my phone that water had been detected. Instead of finding out 10 days after, I was able to act immediately. I called a friend who had a spare key, asked him to check the house, and he quickly shut off the main water supply. That one alert likely prevented what could have been thousands of dollars in damaged floors, walls, and everything in between. It turned a potential disaster into a minor inconvenience. What I appreciate most is the peace of mind it provides, especially when you’re not home. It’s not something you think about daily, but in situations like this, it proves its value instantly. Looking back, it’s hard not to see it as an essential part of a home setup. It’s a simple device, but one that can make a very real difference when it matters most.

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.

Very easy to install
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.
