LightOutput* esphome::light::LightState::output_

protected

Store the output to allow effects to have more access.

Definition at line 287 of file light_state.h.

◆ remote_values

LightColorValues esphome::light::LightState::remote_values

The remote color values reported to the frontend.

These are different from the "current" values: For example transitions will continuously change the "current" values. But the remote values will immediately switch to the target value for a transition, reducing the number of packets sent.

This value does not have gamma correction applied.

This property is read-only for users. Any changes to it will be ignored.

Definition at line 134 of file light_state.h.

◆ remote_values_listeners_

std::unique_ptr<std::vector<LightRemoteValuesListener *> > esphome::light::LightState::remote_values_listeners_

protected

Listeners for remote values changes.

"Remote values" are light color values that are reported to the frontend and have a lower publish frequency than the "real" color values. For example, during transitions the current color value may change continuously, but the remote values will be reported as the target values starting with the beginning of the transition.

Lazily allocated - only created when a listener is actually registered.

Definition at line 316 of file light_state.h.

◆ restore_mode_

LightRestoreMode esphome::light::LightState::restore_mode_

protected

Restore mode of the light.

Definition at line 330 of file light_state.h.

◆ rtc_

ESPPreferenceObject esphome::light::LightState::rtc_

protected

Object used to store the persisted values of the light.

Definition at line 293 of file light_state.h.

◆ target_state_reached_listeners_

std::unique_ptr<std::vector<LightTargetStateReachedListener *> > esphome::light::LightState::target_state_reached_listeners_

protected

Listeners for target state reached.

Notified when the state of current_values and remote_values are equal (when the transition is finished).

Lazily allocated - only created when a listener is actually registered.

Definition at line 324 of file light_state.h.

◆ transformer_

std::unique_ptr<LightTransformer> esphome::light::LightState::transformer_ {nullptr}

protected

The currently active transformer for this light (transition/flash).
