Intensity
Intensity blends the adaptive settings toward a configured endpoint, without leaving adaptive mode. It provides a room-wide "mood" level that still tracks the sun.
The Dial
Each Adaptive Lighting configuration creates a number entity:
number.adaptive_lighting_<name>_intensity
Set it like any other number:
service: number.set_value
target:
entity_id: number.adaptive_lighting_living_room_intensity
data:
value: 60
The value is a percentage, and it interpolates:
output = floor_value + (adaptive_value - floor_value) × intensity / 100
| Intensity | Result |
|---|---|
100 (default) |
The adaptive values, unchanged; interpolation is skipped. |
0 |
The floor. |
| in between | A scaled adaptive curve — the sun still moves the lights at every setting. |
Between 0 and 100, the light keeps following the sun with a smaller range. At 0, the target stays at the endpoint. Both brightness and color are blended, subject to the profile's adaptation switches and each light's manual-control status and supported color modes.
Changing the dial re-adapts eligible, already-on lights immediately rather than waiting for the next interval, even with only_once enabled. It does not turn lights on or clear manual control. While the main switch is off, it stores the value for later. The value survives a restart and is restored before startup adaptation; only_once still prevents startup adaptation.
Choosing the Floor
The floor is set per configuration with intensity_floor:
intensity_floor |
0% gives | Use it when |
|---|---|---|
sleep (default) |
sleep_brightness and the configured sleep color |
You want 0% to match sleep mode. RGB sleep colors are used on color-capable lights; CT-only lights use sleep_color_temp. |
minimum |
min_brightness / min_color_temp |
You want the dial to stay inside the range the adaptive curve already uses. |
minimum never takes a light below what Adaptive Lighting would have done at its darkest anyway. The trade is that it does less and less as the evening goes on, and color stops moving after sunset — the adaptive color temperature is already min_color_temp there, so the floor and the value being interpolated from are the same number.
The sleep endpoint can go below min_brightness. It dims and warms the light only when the sleep settings are dimmer and warmer than the current adaptive target. If you configured a brighter or cooler sleep setting, lowering intensity instead moves toward that setting. Intensity 0 means the configured endpoint, not off.
transition_until_sleep Overrides the Floor
With transition_until_sleep enabled, the adaptive color after sunset moves toward the sleep color. When sleep is warmer than min_color_temp, using the minimum endpoint could make dial-down cool the light during that period.
For that reason the sleep floor is forced whenever transition_until_sleep is on, whatever intensity_floor says. The switch's intensity_floor attribute reports the floor actually in use, so you can see when this applies:
{{ state_attr('switch.adaptive_lighting_living_room', 'intensity_floor') }}
Interaction With Sleep Mode
Sleep mode ignores the dial entirely. Its output already is the sleep value, so scaling towards the floor would be a no-op with the default floor and misleading with the other. Sleep mode behaves identically whatever the intensity is set to.
Attributes
The main switch exposes both values:
| Attribute | Meaning |
|---|---|
intensity |
The current dial value, 0-100. |
intensity_floor |
The floor in use, sleep or minimum, after the transition_until_sleep override. |
change_switch_settings preserves intensity, including when resetting settings to factory or configuration defaults. Set the number to 100 to restore the unmodified adaptive curve. Automations watching brightness_pct see the blended target, so changing intensity can trigger their brightness thresholds.
Why Not Just Scale min_brightness and max_brightness?
An input_number helper and change_switch_settings automation can reproduce this brightness curve by replacing each original bound B with floor + (B - floor) * intensity / 100. Both bounds keep following the sun; this does not freeze the target. The automation needs the original bounds and must keep them in sync when the profile is retuned. Ordinary color-temperature bounds can be transformed similarly, but this alone does not reproduce sleep-RGB blending.
The dial reads the configuration's own numbers, so there is nothing to keep in sync, and it moves color along with brightness.
