LightScene Integration for Home Assistant

LightScene is a custom Home Assistant integration that enhances your lighting control by managing scenes with dynamic brightness scaling and context tracking. Enable brightness scaling and context tracking for Home Assistant scene entities, allowing dynamic control over lighting environments in your smart home.

This component introduces sceneoff functionality and proportional brightness control for lights defined in your Home Assistant scene.

Features

• Automatic discovery: Automatically detects scenes and creates a corresponding light entity for every Home Assistant scene.
• Scene state tracking: Listens for scene activation events to turn on LightScene entities. Tracks scene entity changes to determine if scene has been turned off.
• Togglable: Regular scenes only support being turned on. LightScene lights can be turned on or off.
• Proportional brightness control: Scale brightness of all scene lights in proportion to scene presets.

Configuration

No manual configuration is needed. The component automatically discovers scene entities and creates corresponding LightScene entities.

Example

For example, a scene named Evening Lights with several lights with brightness controls will automatically have a LightScene light entity created with brightness scaling enabled.

Usage

Turning On a Light Scene

Light scenes can be turned on via the Home Assistant UI or through a service call, as usual:

service: light.turn_on
data:
  entity_id: light.evening_lights
  brightness: 150

Turning Off a Light Scene

Turn off the light scene with:

service: light.turn_off
data:
  entity_id: light.evening_lights

Dynamic Brightness Scaling

The component scales brightness based on the baseline brightness of the scene. For example:

• A light with brightness 255 in the scene will scale proportionally to match the specified brightness.

Events

• Scene reload: Automatically updates all LightScene entities when scenes are reloaded.
• Scene activation: Handles external activations of scenes and updates the corresponding LightScene entity.
