Review: YoLink Products are easy to use and work great! - YoLink products are great and easy to use (I've been using them for at least 8 years). I have their HUB, audible alarm, many water sensors, smart plugs, water valve operator, and garage door controllers. They all work seamlessly with their mobile app and are easy to set-up. The water sensors have saved my home from water damage at least 4-times. If you don't have water sensors in your home, it's only a matter of time before you experience a water even that will cost you a lot of money. YoLink's products will pay for themselves many times over because it avoids costly water damage. Garage operators provide peace of mind that garage is not open (plus can operate remotely if needed).

### ⭐⭐⭐⭐⭐ Water Leak Detection
*by D***N on January 4, 2026*

No regrets yet. Setup was a breeze. All the sensors connected on the first try, no problem. The app's super easy to use and has way more features than I'll probably ever use. Can't say for sure how accurate the sensors are, but they haven't gone offline since I put them in. After dealing with a huge water leak before, these sensors are totally worth it for the peace of mind.
