Smart water leak protection with YoLink Water Leak Starter Kit

Protect essential spaces from costly water damage with a plug‑and‑play kit that combines a central hub with six Leak Sensor 4 units. Each sensor features a built‑in 105 dB audible alarm and is designed for quick placement where leaks are most likely to occur. The integrated design helps you respond fast, whether you’re at home or away.

What’s included and what it can do

• Long‑range LoRa connectivity extends coverage beyond typical Wi‑Fi zones, enabling reliable alerts from basements, crawl spaces, or outdoor areas.
• Alerts reach you through the YoLink app, via email, or SMS, and sensors can be named by location for organized monitoring.

Offline reliability and local protection

Even during internet outages, YoLink Control‑D2D lets sensors trigger the siren or activate shutoff actions at the local level, preserving protection when network connectivity is down.

Powerful yet Low‑Maintenance

Each Leak Sensor 4 is powered by two AAA batteries, delivering up to five years of typical life with easy replacement when needed.
