# ๐ Adaptive Lighting: Enhance Your Home's Atmosphere with Smart, Sun-Synchronized Lighting ๐
[Adaptive Lighting](https://github.com/basnijholt/adaptive-lighting) is a custom component for [Home Assistant](https://www.home-assistant.io/) that intelligently adjusts the brightness and color of your lights ๐ก based on the sun's position, while still allowing for manual control.

By automatically adapting the settings of your lights throughout the day, Adaptive Lighting helps maintain your natural circadian rhythm ๐ด, which can lead to improved sleep, mood, and overall well-being. Experience cooler color temperatures at noon, gradually transitioning to warmer colors at sunset and sunrise.
In addition to its regular mode, Adaptive Lighting also offers a "sleep mode" ๐ which sets your lights to minimal brightness and a very warm color, perfect for winding down at night.

## :bulb: Features
When initially turning on a light that is controlled by Adaptive Lighting, the `light.turn_on` service call is intercepted, and the light's brightness and color are automatically adjusted based on the sun's position.
After that, the light's brightness and color are automatically adjusted at a regular interval.
Adaptive Lighting provides four switches (using "living_room" as an example component name):
- `switch.adaptive_lighting_living_room`: Turn Adaptive Lighting on or off and view current light settings through its attributes.
- `switch.adaptive_lighting_sleep_mode_living_room`: Activate "sleep mode" ๐ด and set custom sleep_brightness and sleep_color_temp.
- `switch.adaptive_lighting_adapt_brightness_living_room`: Enable or disable brightness adaptation ๐ for supported lights.
- `switch.adaptive_lighting_adapt_color_living_room`: Enable or disable color adaptation ๐ for supported lights.
### :control_knobs: Regain Manual Control
Adaptive Lighting is designed to automatically detect when you or another source (e.g., automation) manually changes light settings ๐น๏ธ.
When this occurs, the affected light is marked as "manually controlled," and Adaptive Lighting will not make further adjustments until the light is turned off and back on or reset using the `adaptive_lighting.set_manual_control` service call.
This feature is available when `take_over_control` is enabled.
Additionally, enabling `detect_non_ha_changes` allows Adaptive Lighting to detect all state changes, including those made outside of Home Assistant, by comparing the light's state to its previously used settings.
The `adaptive_lighting.manual_control` event is fired when a light is marked as "manually controlled," allowing for integration with automations ๐ค.
The Adaptive Lighting switch exposes these read-only attributes for its lights:
- `manual_control`: lights with any attribute marked as manually controlled.
- `manual_control_brightness`: lights with brightness marked as manually controlled.
- `manual_control_color`: lights with color marked as manually controlled.
These lists report manual-control flags. Actual adaptation also depends on `take_over_control_mode` and the brightness/color adaptation switches. For example, under the default `pause_all` mode, manually changing only brightness leaves `manual_control_color` empty while pausing both brightness and color adaptation. Under `pause_changed`, color can continue adapting.
The attributes are absent when the Adaptive Lighting switch is off. Use a fallback when checking them in templates:
```jinja
{{ 'light.bedroom' in (state_attr('switch.adaptive_lighting_bedroom', 'manual_control_brightness') or []) }}
```
> โ ๏ธ **_Caution: Some lights might falsely indicate an 'on' state, which could result in lights turning on unexpectedly. Disable `detect_non_ha_changes` if you encounter such issues._**

## :gear: Configuration
Adaptive Lighting supports configuration through both YAML and the frontend (**Settings** -> **Devices and Services** -> **Adaptive Lighting**, **Adaptive Lighting** -> **Options**), with identical option names in both methods.
```yaml
# Example configuration.yaml entry
adaptive_lighting:
lights:
- light.living_room_lights
```
If you configure Adaptive Lighting through the UI, no `adaptive_lighting:` entry is needed in `configuration.yaml`. Instances configured through YAML must be edited in YAML.
Transform your home's atmosphere with Adaptive Lighting ๐ , and experience the benefits of intelligent, sun-synchronized lighting today!

input_boolean.sleep_mode.Enhance your control over brightness transitions during sunrise and sunset with
With Adaptive Lighting, you can set a `brightness_mode` to specify how the brightness changes during sunrise and sunset. The `brightness_mode` can be set to `"default"` ([as illustrated in other graphs above](#high_brightness-brightness)), `"linear"`, or `"tanh"`. If you choose to deviate from the `"default"` mode, you can adjust `brightness_mode_time_dark` and `brightness_mode_time_light` to further customize the lighting transitions.
When `brightness_mode` is set to `"linear"`:
- During **_sunset_**, the brightness begins to gradually decrease from `max_brightness` starting at `time=sunset_time - brightness_mode_time_light`, until it reaches `min_brightness` at `time=sunset_time + brightness_mode_time_dark`.
- During **_sunrise_**, the brightness begins to gradually increase from `min_brightness` starting at `time=sunrise_time - brightness_mode_time_dark`, until it reaches `max_brightness` at `time=sunrise_time + brightness_mode_time_light`.
When `brightness_mode` is set to `"tanh"`, it uses the smooth transition of a [hyperbolic tangent function](https://mathworld.wolfram.com/HyperbolicTangent.html):
- During **_sunset_**, the brightness starts to decrease from 95% of `max_brightness` starting at `time=sunset_time - brightness_mode_time_light`, until it reaches 5% of `min_brightness` at `time=sunset_time + brightness_mode_time_dark`.
- During **_sunrise_**, the brightness starts to increase from 5% of `min_brightness` starting at `time=sunrise_time - brightness_mode_time_dark`, until it reaches 95% of `max_brightness` at `time=sunrise_time + brightness_mode_time_light`.
