Operation: Life Safety Response

User Story

As a: Homeowner and family protector,

I want: The home to automatically illuminate all pathways and unlock all exit points when smoke or carbon monoxide is detected,

So that: My family can evacuate the premises as quickly and safely as possible, minimizing the time spent navigating in high-stress or low-visibility conditions.

Acceptance Criteria

Multi-Sensor Redundancy: The automation must trigger if any individual smoke or CO2 sensor in the bedroom, hallway, or upstairs areas reaches an "on" state.
Parallel Alerting: Mobile notifications must be dispatched to all primary users simultaneously with the hardware actions to ensure no delay in human awareness.
Automated Egress: The system must issue an immediate "Unlock" command to the primary Lock Group (exterior doors) to remove physical barriers to exiting.
High-Visibility Strobe: Key transition lights (Bedroom, Playroom, Theater) must strobe between high-contrast colors (Purple/Yellow) for 5 cycles to provide an unmistakable visual alarm.
Full Path Illumination: All interior and exterior zones must transition to 100% brightness at a cool daylight color temperature (5515K) to pierce through potential smoke.
Execution Priority: The automation must run in "Single" mode to ensure the emergency sequence is not interrupted by secondary triggers.

Technical Requirements

Hardware: Z-Wave/Zigbee Smoke & CO Detectors, Smart Deadbolts, Philips Hue/Lutron Lighting Ecosystem, Mobile App Integration.

Software: Home Assistant Core, YAML Automation Engine, Parallel Action Processing.

The Solution: Emergency Egress Automation

This automation prioritizes life safety by executing notifications, lock states, and lighting scenes in a specific sequence designed for rapid evacuation.
