`change_switch_settings` updates a profile while its main switch is off, but lights are adapted only while that switch is on. It preserves manual-control flags, so manually controlled lights remain paused.

<summary>Pause brightness at the minimum using manual control.</summary>
Use the [blueprint](https://github.com/basnijholt/adaptive-lighting/blob/main/blueprints/automation/manual_control_at_minimum.yaml) to mark an individual light's brightness as manually controlled when the calculated target reaches its minimum. The light stays on and the adaptation switches stay enabled. Set `take_over_control_mode: pause_changed` on the profile to keep adapting color; the default `pause_all` pauses both attributes.
Select the profile, its adapt-brightness switch, and a light managed by it. Match the minimum percentage to the profile's `min_brightness`. This YAML example assumes `min_brightness: 1`; change `minimum_pct` and the entity IDs to match your setup.

The comparison uses the rounded 0–255 target, so it does not depend on sampling an exact floating-point minimum. It waits up to five minutes for the light to report that minimum before marking manual control, so the final dimming command can complete. Reported brightness does not prove physical fade completion. If the light, profile, or adapt-brightness switch is toggled, the target rises, brightness is marked manually controlled elsewhere, or brightness never reaches the minimum, the attempt is abandoned. Lights that cannot report the configured minimum will not be paused. Existing manual color flags are preserved, and lights whose brightness is already manually controlled are left alone. Manual-control state is shared for lights managed by multiple profiles, so their existing takeover policies still apply.
The usual resets apply: turning the light off, the configured `autoreset_control_seconds` timeout, clearing manual control through its service, and existing profile/sleep-switch reset behavior. After a reset, normal adaptation can increase brightness again. This runs once per downward crossing; resetting while the target remains at its minimum does not immediately mark the light again. Startup at the minimum is not a crossing either.
This pauses further dimming as well as brightening. To pause brightness immediately after a brightness change made through Home Assistant, use `take_over_control_mode: pause_changed` with `take_over_control: true`; that needs no additional automation.
