Make new Component for "Lighting Interface"
Now we have 2 (or even 3?) ways to control LEDs:
- Directly attached to the ESP, controlled via PWM #5
- Using the PCA9536 GPIO Expander (used in the House exclusively), controlled via I2C
- Upcomming: PCA9956 LED Driver, controlled via I2C
Best way would probably be to create a new component which selects the type of lighting interface used
