Input Ports

This part allows you to publish data to the specified topics. You can send multiple data by adding ports and entering name, topic, Qos level and retain for each port. If you check the box under the topic, the value for that port must include both topic and value (the input value must be a json object with 'topic' and 'value' keys e. g. {'topic': 'foo', 'value': 'bar'}).
