Detect the leak.
Shut off the water. Tell the household.

An alarm should lead to action.

A leak can start while the household is asleep or away. A sound beside the water is easy to miss. Sergey built this system so that any of seven installed GoveeLife Water Leak Detectors triggers a coordinated response: stop the main water supply and make both the problem and its location noticeable. This is an implemented personal home project.

What happens when water is detected?

The triggered detector supplies the leak location to the configured alert. The automation commands the Black & Decker controller to close the main water valve, switches on the main bedroom light, and announces the leak and its location through Google Nest voice and text notifications. SMS and email are also sent, so the event can reach Sergey beyond the room where it started.

Water stays off until it is deliberately restored.

After a leak event the water is not automatically turned back on when the sensor dries. The owner checks the reported location and addresses the cause, then restores the supply through the app. This makes reopening a deliberate step instead of an automatic return to a potentially leaking pipe or appliance.

Useful at night. Useful while away.

At night, the main bedroom light and Nest announcement make the event more noticeable inside the home. While away, SMS and email provide remote notification. The location in the alert helps the owner know where to investigate rather than only knowing that water was detected somewhere.

What to check for another home

A similar installation needs suitable detector placement, reliable hub coverage, compatible valve geometry and a tested automation path. Power, batteries, Wi-Fi, internet and notification services affect operation. Sensors detect water at their sensing points; shutting the main valve does not remove water already released or guarantee protection against every source of water. Periodic detection, valve and notification checks are part of keeping the setup useful.
