Workflow Description

1. Sensor Detection

The Lutron RA2 occupancy sensor detects motion within its range and sends a signal to Home Assistant.

2. Presence Decision

Home Assistant evaluates whether the room is occupied based on the sensor input.

3. Lighting Control

If the room is occupied, Home Assistant triggers the lighting system to turn on.

4. Alert Notification

If unexpected movement is detected when the room is supposed to be empty, Home Assistant sends a security alert.

5. Automatic Deactivation

When the sensor detects no movement after a set period, Home Assistant turns off the lights.

Postconditions

After the capability completes, the lights will be automatically controlled based on occupancy, enhancing safety and energy efficiency.

Optional Enhancements

• Integrate with voice assistants for manual override.
• Set up scheduled lighting patterns for specific times.
• Link with security cameras for visual confirmation of alerts.
