YoLink DIY Water Leak Kit with EVO Valve Operator & Hub

Complete, proactive water protection for homes and small businesses

The YoLink DIY Water Leak Detection & Shut-Off Starter Kit offers a ready-to-install solution to monitor and respond to leaks across multiple spaces. This bundle brings together three YoLink Water Leak Sensors, one Smart Valve Controller, one EVO Valve Operator, and one YoLink Hub. Compact, low-maintenance devices with clear indicators make it easy to protect valuable areas—from basements and laundry rooms to storage closets and server nooks.

Designed for resilience, the system can operate even when power or internet is unstable. The device-to-device (D2D) functionality lets sensors communicate with the valve controller directly, so a detected leak can trigger an automatic shut-off without waiting for cloud connectivity. This combination of local control and remote visibility helps you stay ahead of water surprises with minimal disruption to daily life.

What you get

• Three YoLink Water Leak Sensors
• One Smart Valve Controller
• One EVO Valve Operator
• One YoLink Regular Hub

How it works and where it shines

LoRa-based long-range connectivity powers the system with coverage up to a quarter mile between devices and the hub. This means you can place sensors in hard-to-reach areas, indoor or outdoor, while keeping the entire home or space under protection. Leaks trigger automatic valve actuation, delivering a fast, quiet response that can prevent water damage before it escalates.

When a leak is detected, you receive timely alerts through multiple channels. Choose SMS, app, or email notifications, and iOS Critical Alerts for high-priority events. The kit includes generous SMS allowances, with 30 free SMS alerts available out of the box (5 per device for up to 5 devices), plus additional allowances as you add more devices.

Smart features and integrations

• Seamless third-party integrations with Alexa, Google Assistant, IFTTT, and Home Assistant for voice control and automation.
• Battery-powered longevity: leak sensors last up to 5 years, while the Valve Controller 2 runs up to 2 years on batteries or can be powered directly with the battery serving as a reliable backup.

Installation and everyday use

No plumbing is required to set up the EVO Valve Operator. The system is designed for quick installation and reliable operation, so you can configure the hub, sensors, and valve controller and begin monitoring with minimal effort.

While no solution can guarantee outcomes, this kit offers an effective, flexible approach to detecting leaks early, automating shut-off when needed, and keeping you informed so you can respond promptly. The result is a practical, scalable way to guard against water surprises while maintaining peace of mind.
