MQTT

Overview

This bundle of advanced actions allows you to connect to a MQTT broker to achieve the following actions:

Publish a message
Subscribe to a topic
Receive the content of the message sent by the broker
Unsubscribe from topic

A typical use is to subscribe to a topic and receive messages. You can extract information through a variable and reuse it later in your workflow.
