How to tidy up automations on my dashboard

Im trying to add a new automation consisting of a toggle for an mqtt command. I need to set the toggle to send ‘1’ or ‘0’ depending the position of the switch.

I realized I have a bit of a mess of my toggles, most likely redundant. This is what my dashboard looks like:

I sorta understand that things can be done via the configuration.yaml, which was how I set up my kompressor and solenoid toggle switches. But when I was setting those up I think I created the booleans by mistake (on the left). Here is my configuration.yaml:

# Example configuration.yaml entry
input_boolean:
  notify_home:
    name: Publish MQTT msg
    icon: mdi:car

  power_kompressor:
    name: Kompressor
    icon: mdi:car

  power_solenoid:
    name: Solenoid
    icon: mdi:car

# MQTT Switches RPi2 - RPi3
switch:
  - platform: mqtt
    name: kompressor
    command_topic: "test_channel"
    payload_on: "komp-on"
    payload_off: "komp-off"
  - platform: mqtt
    name: solenoid
    command_topic: "test_channel"
    payload_on: "sole-on"
    payload_off: "sole-off"
    

Honestly I think the booleans I created by mistake and are not needed. I just use the toggle switches to controle my kompressor and solenoid.

Then they came up with automations.yaml which I believe moved some code automatically into that file because I know I didnt set those up manually in code as I did with the configuration.yaml.

If im not mistaken, the other way to create automations is through the configuration menu option, thru the UI. But I get errors when trying to create it:


What I want is to add my new automation the proper way (automation.yaml or UI) and tidy up whatever else I should in the case of something being redundant. The UI option confuses me because I think I need to create the device first and then the toggle and finally the automation:
