Just /npc/ (where I used to be able to edit files).
You edit the message in doorbell.sh on the doorbell to reflect your username and password, and the IP of your MQTT Broker, then in Home Assistant you can create an Automation with trigger MQTT, topic Home/Groundfloor/Outside/Doorbell followed by whatever you want when someone rings your doorbell.
Something like this:
	
	
	
		Code:
	
	
		alias: Doorbell_Notify
description: ''
trigger:
  - platform: mqtt
    topic: Home/Groundfloor/Outside/Doorbell

  - service: script.turn_on

      entity_id: script.doorbell_sonos
