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 range—up 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.
