| name: "Dynamic Light Brightness (Lux Based)" | |
| description: > | |
| This blueprint dynamically adjusts a light's brightness to complement the ambient light levels detected by an illuminance (lux) sensor. | |
| It maps a defined range of lux values (from a minimum to a maximum) to a corresponding brightness range (e.g., 10 lux → 10% brightness, 500 lux → 100% brightness). The brightness is calculated using linear interpolation, ensuring smooth transitions as the ambient light changes. | |
| The automation is only active when the target light is already turned on. | |
