Water protection
Know about a leak. Then decide what happens next.
Build a YoLink system for simple leak alerts or pair compatible sensors and valve control for an automatic response.
Product compatibility and installation requirements vary. Review the selected product page before purchase.

How the system works
From detection to response.
Start with the outcome you need, then choose compatible components.
- 01Detect
A sensor recognizes water at a risk point such as a sink, appliance, water heater, or mechanical space.
- 02Alert
The hub connects the system to supported app, email, or audible notifications configured for the product.
- 03Respond
A compatible valve-control configuration can be set up to shut off water when its paired conditions are met.

Before you buy
The questions that change what you need.
Do I need a YoLink hub?
For app access and remote alerts, choose a compatible YoLink hub with an internet connection. If you do not have one, compare starter kits that include a hub; if you already do, check the sensor or valve product page for its exact hub requirement and box contents.
Will a leak sensor shut off my water by itself?
No. A sensor detects water and can send supported alerts through a connected hub. Automatic shutoff also needs a compatible valve controller or operator and a configured sensor-to-valve action. Check the selected products for compatibility and what is included.
Which leak-sensor style should I choose?
The right style depends on where water is likely to appear and how much area must be covered. Puck, probe, and rope-style sensors serve different placement needs.
How do I know whether a valve operator will fit?
Check your existing valve type and size, plus the space and orientation around its handle. Review the selected operator’s dimensions and compatibility information before purchase. If the fit is uncertain, contact support with photos of the valve and installation area.
What works if my internet goes out?
App access and remote alerts require a YoLink hub with an internet connection. After prior Control-D2D pairing, compatible water sensors can trigger a paired valve during an internet outage if both devices remain powered and in radio range. Confirm that the specific sensor and valve support this setup.
