• 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.
• Group ID Filters
  • A comma seperated separated list of group IDs to subscribe to ignore.  If no group IDs are to be ignored, this should be left empty

When the 2nd publish is received it will overwrite the first tag because "two" is now a folder instead of a tag.  This folder/tag name collision can be avoided by specifying the Tag Name to always use for tags. 

Custom Namespace JSON Example

Let say we have a publish received on the topic "test/data/json" with value '{ "stringTag" : "12345", "folderTag" : { "intTag" : 1, "boolTag" : true } }'. MQTT Engine will create a three folders "test", "data" and "point" followed by a tag/folder structure representing the JSON value of the payload.
