Choose the Right Leak Sensor for You
YoLink offers two leak sensors for different needs. Water Leak Sensor 1 is a quiet, discreet option that relies on phone notifications. Water Leak Sensor 4 adds a loud built-in siren, making it ideal for high-risk areas like basements or garages. Both connect to the YoLink Hub for instant alerts.

5-Year Battery Life
Runs on 2 AAA batteries (included) for up to 5 years of nonstop leak protection.

LoRa Long-Range Signal
Stays connected up to 1/4 mile, even through walls and floors where WiFi fails.

IP68 Waterproof Build
Fully sealed design survives direct water contact, perfect for damp or flood-prone areas.

Smart Alerts & Integrations
Receive instant app, SMS, or email alerts. Works with Alexa, IFTTT, Home Assistant, and more.

Works Even Without WiFi or Power
Power down? WiFi out? No problem. With YoLink’s D2D direct control, Leak Sensors continue to work seamlessly with YoLink Smart Valves and Water Meters, shutting off water the moment a leak is detected—no cloud, no delay, no worries.
