Can someone please help me with 3 more automations?

Create an Input Select containing the names of the colors want:

  • red
  • blue
  • green
  • white

Then create the following automation:

alias: color changer
trigger:
  - platform: state
    entity_id:
      - sensor.sonoff_bedroomr5
    to: button_3_single
condition: []
action:
  - service: light.turn_on
    data:
      color_name: "{{ states('input_select.colors') }}"
      brightness_pct: 100
    target:
      device_id: bedroomled
  - service: input_select.select_next
    target:
      entity_id: input_select.colors
