By automatically adapting the settings of your lights throughout the day, Adaptive Lighting helps maintain your natural circadian rhythm π΄, 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" π which sets your lights to minimal brightness and a very warm color, perfect for winding down at night.

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" π΄ and set custom sleep_brightness and sleep_color_temp.switch.adaptive_lighting_adapt_brightness_living_room: Enable or disable brightness adaptation π for supported lights.switch.adaptive_lighting_adapt_color_living_room: Enable or disable color adaptation π for supported lights.
Adaptive Lighting is designed to automatically detect when you or another source (e.g., automation) manually changes light settings πΉοΈ.
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 π€.
β οΈ Caution: Some lights might falsely indicate an 'on' state, which could result in lights turning on unexpectedly. Disabledetect_non_ha_changesif you encounter such issues.

Adaptive Lighting was initially inspired by @claytonjn's hass-circadian_lighting, but has since been entirely rewritten and expanded with new features.
Encountering issues? Enable debug logging in your configuration.yaml:
logger:
default: warning
logs:
custom_components.adaptive_lighting: debugAfter the issue occurs, create a new issue report with the log (/config/home-assistant.log).
Adaptive Lighting sends more commands to lights than a typical human user would. If your light control network is unhealthy, you may experience:
- Laggy manual commands (e.g., turning lights on or off).
- Unresponsive lights.
- Home Assistant reporting incorrect light states, causing Adaptive Lighting to inadvertently turn lights back on.
Most issues that appear to be caused by Adaptive Lighting are actually due to unrelated problems. Addressing these issues will significantly improve your Home Assistant experience.
In case lights are suddenly turning on by themselves, this is most likely due to the light incorrectly reporting an "on" state to Home Assistant, leading to an undesired Adaptive Lighting action.
To prevent adapting in cases where the state of the light is suddenly "on" and only adapt if there is an associated light.turn_on service call, set detect_non_ha_changes: false.
Ensure your light bulbs have a strong WiFi connection. If the signal strength is less than -70dBm, the connection may be weak and prone to dropping messages.
Mesh networks typically require powered devices to act as routers, relaying messages back to the central coordinator (the radio connected to Home Assistant). Philips lights usually function as routers, while Ikea, Sengled, and generic Tuya bulbs often do not. If devices become unresponsive or fail to respond to commands, Adaptive Lighting can exacerbate the issue. Use network maps (available in ZHA, zigbee2mqtt, deCONZ, and ZWaveJS UI) to evaluate your network health. Smart plugs can be an affordable way to add more routers to your network.
For most Zigbee networks, using groups is essential for optimal performance. For example, if you want to use Adaptive Lighting in a hallway with six bulbs, adding each bulb individually to the Adaptive Lighting configuration could overwhelm the network with commands. Instead, create a group in your Zigbee software (not a regular Home Assistant group) and add that single group to the Adaptive Lighting configuration. This sends a single broadcast command to adjust all bulbs, improving response times and keeping the bulbs in sync.
As a rule of thumb, if you always control lights together (e.g., bulbs in a ceiling fixture), they should be in a Zigbee group. Expose only the group (not individual bulbs) in Home Assistant Dashboards and external systems like Google Home or Apple HomeKit.
β οΈ If you control lights individually,manual_controlcannot behave correctly! If you need to control lights individually as well, use a Home Assistant Light Group.
Bulbs from different manufacturers or models may have varying color temperature specifications. For instance, if you have two Adaptive Lighting configurationsβone with only Philips Hue White Ambiance bulbs and another with a mix of Philips Hue White Ambiance and Sengled bulbsβthe Philips Hue bulbs may appear to have different color temperatures despite having identical settings.
To resolve this:
- Include only bulbs of the same make and model in a single Adaptive Lighting configuration.
- Rearrange bulbs so that different color temperatures are not visible simultaneously.
These lights are known to exhibit disadvantageous behaviour due to firmware bugs, insufficient functionality, or hardware limitations:
- Sengled Z01-A19NAE26
- Unexpected turn-ons: If Adaptive Lighting sends a long transition time (like the default 45 seconds), and the bulb is turned off during that time, it may turn back on after approximately 10 seconds to continue the transition command. Since the bulb is turning itself on, there will be no obvious trigger in Home Assistant or other logs indicating the cause of the light turning on. To fix this, set a much shorter
transitiontime, such as 1 second. - Heat sensitivity: Additionally, these bulbs may perform poorly in enclosed "dome" style ceiling lights, particularly when hot. While most LEDs (even non-smart ones) state in the fine print that they do not support working in enclosed fixtures, in practice, more expensive bulbs like Philips Hue generally perform better. To resolve this issue, move the problematic bulbs to open-air fixtures.
- Unexpected turn-ons: If Adaptive Lighting sends a long transition time (like the default 45 seconds), and the bulb is turned off during that time, it may turn back on after approximately 10 seconds to continue the transition command. Since the bulb is turning itself on, there will be no obvious trigger in Home Assistant or other logs indicating the cause of the light turning on. To fix this, set a much shorter
- Ikea Tradfri bulbs/drivers (and related Ikea smart light products)
- Unsupported simultaneous transition of brightness and color: When receiving such a command, they switch the brightness instantly and only transition the color. To get smooth transitions of both brightness and color, enable
separate_turn_on_commands. - Unresponsiveness during color transitions: No other commands are processed during an ongoing color transition, e.g., turn-off commands are ignored and lights stay on despite being reported as off to Home Assistant. The default config with long transitions thus results in long periods of unresponsiveness. To work around this, disable transitions by setting
transitionto0, and increase the adaptation frequency by settingintervalto a short time, e.g.,15seconds, to retain the impression of smooth continuous adaptations. Keeping theinitial_transitionis recommended for a smooth fade-in (lights are usually not turned off momentarily after being turned on, in which case a short period of unresponsiveness is tolerable).
- Unsupported simultaneous transition of brightness and color: When receiving such a command, they switch the brightness instantly and only transition the color. To get smooth transitions of both brightness and color, enable
These graphs were generated using the values calculated by the Adaptive Lighting sensor/switch(es).
Enhance your control over brightness transitions during sunrise and sunset with brightness_mode (click here to learn more π§ ).
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), "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_brightnessstarting attime=sunset_time - brightness_mode_time_light, until it reachesmin_brightnessattime=sunset_time + brightness_mode_time_dark. - During sunrise, the brightness begins to gradually increase from
min_brightnessstarting attime=sunrise_time - brightness_mode_time_dark, until it reachesmax_brightnessattime=sunrise_time + brightness_mode_time_light.
When brightness_mode is set to "tanh", it uses the smooth transition of a hyperbolic tangent function:
- During sunset, the brightness starts to decrease from 95% of
max_brightnessstarting attime=sunset_time - brightness_mode_time_light, until it reaches 5% ofmin_brightnessattime=sunset_time + brightness_mode_time_dark. - During sunrise, the brightness starts to increase from 5% of
min_brightnessstarting attime=sunrise_time - brightness_mode_time_dark, until it reaches 95% ofmax_brightnessattime=sunrise_time + brightness_mode_time_light.
Notice the values of brightness_mode_time_light and brightness_mode_time_dark in the text box.
