What is the difference between the state and command topic as seen in the below example:

switch 1:

    • platform: mqtt*
  • name: “MQTT Switch 1”*
  • state_topic: “/house/switchConfirm1/”*
  • command_topic: “/house/switch1/”*
  • payload_on: “1”*
  • payload_off: “0”*
  • qos: 0*
  • retain: true*

How is it different from the MQTT protocol publish and subscribe topic?
