Шьем свою ESP прошивкой с MQTT отсюда. В Home Assistant в configuration.yaml добавляем:

input_number:
  gl_brightness:
    name: Brightness
    initial: 10
    min: 1
    max: 255
    step: 1
    icon: mdi:brightness-6
  gl_speed:
    name: Speed
    initial: 30
    min: 0
    max: 255
    step: 1
    icon: mdi:speedometer

  gl_scale:
    name: Scale
    initial: 30
    min: 1
    max: 100
    step: 1
    icon: mdi:ruler
    
input_select:
  gl_effect:
    name: Effects
    options:
      - "Конфетти"
      - "Огонь"
      - "Радуга верт."
