Workflow Description

1. Leak Detection

A water leak sensor detects moisture and sends a signal to the home capability system.

2. Check Water Status

The system checks if the water supply is currently on.

3. Shut Off Water Valve

If the water is on, the system sends a command to the Elexa Guardian to shut off the valve.

4. Notify Homeowner

The homeowner receives a notification alerting them of the leak and that the water has been shut off.

5. Monitor System Status

The system continues to monitor the leak until it is resolved or the water valve is manually reset.

Postconditions

The water supply is shut off, preventing further damage, and the homeowner is alerted to the situation for further action.

Optional Enhancements

• Integration with smart home assistants for voice alerts.
• Adding a manual override feature for the water valve.
• Implementing a logging system to track past leak events.
