The YoLink Water Leak Starter Kit provides reliable, long-range flood and leak detection to protect your home from costly water damage. This complete kit includes a YoLink Hub and four smart water leak sensors, designed for basements, bathrooms, laundry rooms, kitchens, and more. Powered by LoRa technology, the system delivers superior wireless coverage, even in hard-to-reach areas like basements or detached garages.
Unlike traditional leak detectors, YoLink features Device-to-Device (D2D) control, ensuring critical alerts and automations work locally—even during internet or power outages. Each sensor is built with Smart Device Integrity Monitoring (S.D.I.M.), so you’ll be notified if a battery is low or if communication is lost. With an ultra-low-power design, the sensors can run for over five years on standard AAA batteries, reducing maintenance and ensuring long-term peace of mind.
The kit is easy to install with Scan-and-Play setup through the YoLink app, making it beginner-friendly while still offering advanced smart home integrations. Connect seamlessly with Alexa, IFTTT, and Home Assistant to create custom automations and voice-controlled monitoring.
Whether you want to protect your basement, monitor under-sink areas, safeguard near water heaters, or keep an eye on a vacation property, the YoLink Water Leak Starter Kit offers a complete, scalable solution for whole-home protection.
