Detect Water Early
Place leak sensors near floors, pans, cabinets, appliances, and utility areas where water is likely to appear first.

Application Example
Automatic Water Shutoff
Pair YoLink leak sensors with a compatible valve solution for local YoLink D2D shutoff, while the YoLink Hub enables app setup, remote alerts, history, and device management.
Automatic shutoff depends on compatible products, correct installation, D2D pairing, valve compatibility, and routine testing.
Beyond AlertsDetect water and trigger an automatic shutoff response.
Water Waste RiskHousehold leaks can waste nearly 10,000 gallons per year.
Local D2D ActionPaired devices can act locally after setup.
Verified SetupTest the sensor-to-valve action before relying on automatic shutoff.
How It Works
Detect, shut off locally, and stay informed
YoLink helps connect leak detection with local valve shutoff and configurable remote alerts.
2
Trigger Local D2D Shutoff
After D2D pairing, a leak sensor can send a local close command to a compatible valve device.
3
Stay Informed Your Way
Based on your YoLink alert settings, you can receive app push notifications, SMS, and email alerts, while the app shows device status and history.
YoLink D2D
Local action without relying on internet
YoLink D2D is the key technology behind this application example. After setup, compatible YoLink devices can trigger local device-to-device actions directly, so a leak sensor can command a paired valve device even when internet service is unavailable.
When both paired devices are battery-powered and properly configured, the local D2D action can continue without home internet or AC power. The YoLink Hub and app are still used for setup, remote notifications, history, device management, and full smart features.

Valve Options
Choose by Installation Type
Start with the installation method. Some shutoff solutions are installed directly into the water line and require pipe cutting, while retrofit options can work with an existing compatible ball valve.
Pipe-Cut Installation
Requires PlumberPipe Cutting Required
Integrated Motorized Valve
For new or planned plumbing installations.
An all-in-one motorized valve installed directly into the water line. Requires correct pipe sizing and professional installation.
Pipe-Cut Installation
Requires PlumberPipe Cutting Required
Controller + Motorized Ball Valve
For controller-based inline shutoff.
Use a YoLink valve controller with a compatible motorized ball valve purchased for the setup.
Controller options: YS5001 or YS5003.
No-Cut Retrofit
No Plumber NeededNo Pipe Cutting
Controller + Valve Operator
For existing compatible lever-style ball valves.
Use a YoLink valve controller with a valve operator to turn the existing valve without cutting the pipe.
Operator options: YS5004EVO or Bulldog Valve Robot. Controller options: YS5001 or YS5003.
Not all valves fit every home. Always check pipe size, valve type, available space, power requirements, and installation instructions before choosing a valve solution.
Placement Priority
Start where a small leak can become expensive
There is no universal ranking for every home. These are practical residential placement priorities because they combine water supply, hidden locations, or long unattended periods.
Water heater
Pan, nearby floor, utility closet.
Washing machine
Supply hoses and floor area.
Sink cabinet
Hidden drips under kitchen or bath sinks.
Refrigerator line
Ice maker or water dispenser supply.
Dishwasher
Cabinet toe-kick and nearby flooring.
Sump pump
Basement floor and pump area.
Toilets
Tank, supply line, and floor edge.
Vacant homes
Vacation homes, rentals, and second homes.
Data note: According to EPA WaterSense, the average household's leaks can waste nearly 10,000 gallons of water per year. Placement categories here are practical risk-priority areas for residential leak detection, not a guarantee of event frequency for every home.
