Main

• Enabled
  • Whether or not the MQTT Engine module is enabled and connecting to configured MQTT Servers.
    
• Primary Host ID
  • The primary host ID to use for 'state' checks.  These checks are used to ensure that the primary backend MQTT Engine client remains connected.  If the primary host ID is set, MQTT Engine will publish it's connection state on a topic that contains the Primary Host ID.  In the event that MQTT Engine becomes disconnected from the server, a death certificate will be published on the same topic, setting the state to 'offline'.  Any connecting client that subscribes on the state topic will then be notified of the MQTT Engine state and walk to the next server is MQTT Engine is offline.
  • This must contain only letters, numbers, and the following special characters: . $ % @ ! - _ ^ *
