YoLink Water Leak Sensor 3-Pack | Long-Range LoRa, No WiFi Needed, Smart Alerts

Smart protection that travels farther and stays online without WiFi

The YoLink Water Leak Sensor 3-Pack brings three compact, battery-powered sensors that watch for leaks around your home’s most vulnerable spots. Using LoRa technology, these sensors communicate with a YoLink Hub (sold separately), delivering encrypted alerts without relying on your WiFi or internet connection. The result is a discreet, resilient monitoring setup you can trust during outages or network hiccups.

How it works

• Long-range LoRa networking covers up to 1/4 mile in open air, with strong penetration to basements, sheds, and outdoor spaces.
• Device-to-device (Control-D2D) pairing keeps monitoring active even when power or internet is unstable.
• Batteries are included—two replaceable AAA cells designed for years of service.

Where to use

• Place near toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, sump pumps, and other water-prone locations.
• Ideal for areas where WiFi is weak or inconsistent, such as basements, garages, or outdoor structures.

Alerts and smart home compatibility

• Notifications can come via SMS, email, or push alerts to your phone or tablet.
• Integrates with Alexa, IFTTT, and Home Assistant for broader automations and routines.

Setup and what’s included

• A YoLink Hub is required for full app access, battery status checks, and remote control.
• Starter kit options are available, and the system works best as part of a growing family of YoLink devices.
• Three sensors come with batteries included, ready to be placed near potential leak sources.

With its emphasis on range, reliability, and encrypted communication, the YoLink Water Leak Sensor 3-Pack offers a practical, scalable way to monitor for leaks and stay informed. The setup is simple, and the potential use cases span from small apartments to larger properties with multiple water-prone zones. While no system can guarantee leak prevention, this kit provides a proactive tool to help you respond quickly when a leak is detected, improving peace of mind without demanding constant maintenance.
