            data:
              name: thanh

    ymlr-mqtt:
      uri: mqtt://user:pass@mqtt
    vars:
      mqtt1: ${this}

  - ymlr-mqtt'pub:
      mqtt: ${ $vars.mqtt1 }
      topics:
        - topic1

        - ${ $parentState.topicName }       # - Topic name
        - ${ $parentState.topicData }       # - Received message which is cast to object
        - ${ $parentState.topicMsg }        # - Received message which is text

        - ...
        # Other elements

Used in global mqtt

  - name: Global MQTT
    ymlr-mqtt:

              # Other elements

Or reuse by global variable

  - name: Global MQTT
    ymlr-mqtt:
      uri: mqtt://user:pass@mqtt
    vars:
      mqtt1: ${this}

  - name: "[mqtt] localhost"
    ymlr-mqtt'sub:
