esphome-dali

A simple esphome integration for light brightness/on/off control of DALI lights using the LW14 adapter.

Example

dali:
    id: dali_bus

light:
  - name: Küche
    id: light0
    platform: dali
    bus: dali_bus
    short_address: 0
  - name: Arbeitszimmer
    id: light1
    platform: dali
    bus: dali_bus
    short_address: 1

  • Much more complete but also more complicated to use.
  • Should be possible to adapt to use with LW14, but I couldn't get it to work.
