# Motion Light Automation Blueprint

This blueprint creates a smart motion-activated light control system. It handles motion detection, luminance-based triggering, and manual override detection to provide intelligent lighting automation.

## Features

- Multiple motion sensor support (triggers on ANY sensor)
- Condition switches (ALL must be ON for automation to work)
- Multiple lights and/or switches control
- Light groups and area-based targeting (native area picker)
- Configurable timeout delay before turning off
- Minimum on duration (prevents rapid on/off cycling)
- Motion sensor on/off debounce (filter false triggers and PIR drop-outs)
- Smooth light transitions with configurable duration
- Luminance sensor support (only trigger in dark conditions)
- Time-based conditions (only active during specified hours)
- Day/Night mode (different light settings based on time)
- Scene support (activate scenes instead of light parameters)
- Dim before off (visual warning before turning off)
- Manual override detection (stops automation if user changes light) with configurable grace period
- Brightness threshold (only trigger if light is dim)
- Custom light parameters (brightness, color, etc.)
- Callback actions for enable/disable/manual events
- Debug notifications for troubleshooting

## State Machine

The automation tracks these states via persistent storage:

| State | Value | Description |
|-------|-------|-------------|
| NONE | 0 | Idle, waiting for motion |
| ENABLING | 2 | Light turn-on command sent, waiting for state change |
| ENABLED | 1 | Light is ON and controlled by automation |
| MANUAL | 3 | User took control, automation paused until light turns off |

## Behavior Notes

- Will NOT turn on light if it's already ON (prevents hijacking user control).
- If user **changes** the light while automation is active (e.g., dim, color, scene), enters MANUAL mode (after grace period).
- If the user **turns the light ON** while the automation is idle (pre-emptive manual control), it enters MANUAL mode and fires the `manual_action` callback. The `disable_action` callback is **not** run in this case (nothing was enabled to disable).
- If the light is **turned off** by any external source while motion is still active, the automation re-enables it (external turn-off recovery). To intentionally exit the automation, also turn off the corresponding **condition switch** — this routes through the disable path and respects the configured timeouts.
- Grace period prevents false manual overrides from delayed device state reports (e.g., Zigbee) — including stray reports that can follow a turn-off.
- MANUAL mode exits when light is turned OFF (by any means).
- Timeout delay only applies when turning OFF (motion cleared).
- Time conditions support overnight windows (e.g., 22:00 to 06:00).
- Day/Night mode uses separate time window from time conditions.

### Brightness threshold interaction

`brightness_threshold` is checked only when the automation decides whether to **enable**. A light that is on but dimmer than the threshold is treated as "available to take over" — so the automation will run with that light. When the disable path runs, it will turn the light **off** (it does not restore a below-threshold dim state).

### Callback ordering and `mode: restart`

Light state changes feed back into the automation, which uses `mode: restart` to handle rapid bursts. To make sure callbacks aren't silently dropped when the automation restarts mid-action, both `enable_action` and `disable_action` run **before** the corresponding turn-on/turn-off command.

## Requirements

- At least one motion sensor.
- `input_text` entity for persistent state storage. Each automation instance must have its own entity. Increase the entity's `max_length` (default 100) to **at least 255** to leave room for the JSON state — short values can cause silent truncation.
- Target light(s), switch(es), group, or area to control.
