# Sleep Mode

Sleep mode is a special operating mode that sets your lights to minimal brightness and very warm color, perfect for winding down at night without disrupting your circadian rhythm.

## Activating Sleep Mode

Each Adaptive Lighting configuration creates a sleep mode switch:

```
switch.adaptive_lighting_sleep_mode_<name>
```

Turn it on to activate sleep mode:

```yaml
service: switch.turn_on
target:
  entity_id: switch.adaptive_lighting_sleep_mode_living_room
```

## Configuration Options

Sleep mode is configured through the main Adaptive Lighting configuration. See the [Configuration](../configuration.md) page for the full options table. The sleep-related options are:

| Option | Default | Description |
|--------|---------|-------------|
| `sleep_brightness` | 1 | Brightness percentage in sleep mode |
| `sleep_rgb_or_color_temp` | `color_temp` | Use `rgb_color` or `color_temp` in sleep mode |
| `sleep_color_temp` | 1000 | Color temperature in Kelvin for sleep mode |
| `sleep_rgb_color` | `[255, 56, 0]` | RGB color for sleep mode |
| `sleep_transition` | 1 | Transition duration in seconds |
| `transition_until_sleep` | false | Gradually transition to sleep settings after sunset |

With `skip_brightness_increases` enabled, leaving sleep mode does not necessarily restore the normal brighter target. The light's reported sleep brightness remains the automatic ceiling because Adaptive Lighting does not store restoration state. To brighten, send a direct brightness request while the light is already on or disable `skip_brightness_increases`. An explicit brightness that also turns the light on still follows `adapt_only_on_bare_turn_on` and takeover-control rules.

## Automation Examples

See [Automation Examples](../automation-examples.md) for sleep mode automation recipes, including:

- Toggle sleep mode using an `input_boolean`
- Set sunrise/sunset based on alarm time
