YoLink Water Leak Sensor 2 – 1/4 Mile LoRa Range, 105dB Siren, Hub Required

Overview

YoLink Water Leak Sensor 2 is a battery powered, long range monitoring solution designed to stay effective even when WiFi or power is unstable. Built on LoRa technology, it forms a resilient, device based network that can alert you to leaks before small drips become disruptive. The system is designed for ease of use and versatile placement, so you can tailor protection to the exact spots in your home that matter most.

Engineered for reliability, this sensor supports a self-contained network that can function without a constant internet connection. When paired with a YoLink Hub, it supports smart home workflows and local alerts, helping you stay informed across rooms and levels without relying solely on cloud connectivity.

Key advantages

• LoRa based range up to 1/4 mile in open air for broader coverage
• Battery life of 2+ years with low power consumption
• No reliance on WiFi or constant internet for core detection
• Device to device pairing keeps core operation even if internet or power is interrupted
• Rope style water sensing cable at 4.2 feet, expandable with additional cables
• Built in siren up to 105 dB for immediate local alerts
• Easy setup via Scan & Play QR code and simple wall mounting

In practice, the system is designed to be discreet yet effective. Long range coverage helps you monitor multiple areas from a central point, while the high visibility alert and audible siren provide quick confirmation of a potential issue even when you are away from home.

Flexible installation in tight spaces

The rope style cable is 4.2 feet long and can be extended with additional cables to cover under appliances, along pipes, or around a water heater. This flexibility lets you define precise detection zones where leaks are most likely, without sacrificing aesthetic or space.

Easy setup and ongoing peace of mind

• Scan & Play QR code in the YoLink app for quick pairing
• No need to plug into an AC outlet to operate
• Hub is required to enable operation and smart home integrations

Smart home compatibility and use scenarios

With a YoLink Hub, the sensor can integrate with Alexa and IFTTT, enabling routines that respond to detected leaks. The built in siren adds a local audible alert, while remote notifications keep you informed wherever you are.

Real world use cases

• Place around a water heater, under sinks, or near a dishwasher to monitor potential drips
• Install in basements, laundry rooms, or utility closets where water is a concern
• Use in vacation homes or multi room setups where stable WiFi is not guaranteed
• Combine with other YoLink devices for a coordinated, multi sensor protection plan

Note the hub is not included and must be added to enable full functionality. This sensor emphasizes reliability, local alerts, and smart home integration to help you stay informed and respond quickly without overpromising results.
