Features

  • Comprehensive Leak Detection Kit: Protect your home from water damage with 2 highly sensitive leak sensors, ideal for bathrooms, kitchens, basements, and other high-risk areas. Receive immediate alerts to stop leaks before they cause costly damage.
  • Industry-Leading Long-Range Technology: Powered by LoRa technology, the YoLink Hub ensures unparalleled rangeup to 1/4 mile in open air. Ideal for areas where traditional Wi-Fi coverage struggles, including basements, sheds, and remote buildings. Note: YoLink devices do not connect to Wi-Fi; instead, they communicate with the Hub, which requires either an Ethernet connection or a 2.4GHz Wi-Fi network.
  • Instant Notifications, Anywhere: Stay informed with real-time app, email and SMS alerts when a leak is detected. Take timely action to safeguard your home, no matter where you are.
  • Reliable, Long-Lasting Performance: Each leak sensor includes replaceable AAA batteries with an impressive lifespan of up to 5 years, ensuring continuous protection without frequent maintenance.
  • Effortless Installation: Designed for easy setup, the sensors can be installed in seconds. Simply place them under appliances, near plumbing, or in high-risk areas like water heaters, sump pumps, or washing machines.
  • Robust Connectivity Options: The YoLink Hub supports both Ethernet and WiFi (2.4GHz only) for flexible connectivity. Use the "Plug, Plug & Play" setup for a quick and hassle-free start.
  • Uninterrupted Operation with Control-D2D Technology: Stay protected even during power outages or internet disruptions. Patented Control-D2D device-to-device pairing ensures seamless functionality between the YoLink Leak Sensor and other compatible YoLink devices, such as the YoLink Valve Controller (sold seperately).
  • Requirements and Free App Features: Compatible with Android and Apple smartphones. Includes a free app with 5 monthly SMS alerts per device (this kit provides 10 SMS alerts per month) and affordable options for additional alerts.

  • Easy to set up, works perfectly.
Style: 0 dB 2 Sensors
I bought this because occasionally the drain tube on my air conditioner gets clogged up and leaks water into the basement floor. It was extremely easy to set up. And I’ll be darned, less than 36 hours later, that’s exactly what happened. I got the alert and was able to solve the problem immediately.

  • Good insurance
Style: 0 dB 2 Sensors
Bought after a slow dishwasher leak created a huge mold problem. I tested the sensor in a small spill and it works. Hopefully will know about leaks before they become a problem in the future.

  • Reliable sensor. Phone notification.
Style: 0 dB 2 Sensors
Reliable leak detector without the loud alarm. Connect to your local internet, place in area, forget. Install app forget. Leak detected phone notifies you. Super easy and love it. Love it. I've used loud alarm ones before and that works if you're there or can hear it. If you're not there you can't turn the loud alarm ones off so it annoys the neighbors or you miss the leak then it defeats the purpose. I love this yolink one because it digitally notifies you if there is a link. It's great if you're a way form work or out of town and it says leak detected. This is exceptionally helpful. These have a 5 yr battery life supposably so you do not have to replace them every couple of years like others. I'd rather invest into a sensor than have thousands of dollars of water damage. ... show more

  • Excellent customer service.
Style: 0 dB 2 Sensors
Very good customer service. I couldn’t figure out how to get the water leak notifications to show up on my phone even though I thought I was doing it correctly in my settings. Customer service was very patient, very helpful, and in no time the system is up and running. I tested it several times, and it’s great! ... show more

  • great product
Style: 0 dB 2 Sensors
Setup was surprisingly easy. I’m not super tech-savvy, but the app walks you through everything. The sensors connected to the hub right away, and I placed one under the kitchen sink and another in the laundry room.
