  • When you select Configuration Nodes from the menu, the Config tab opens beneath the canvas to display used and unused nodes.
  • When you delete a node from a flow, it may not be deleted from the back end.
  • Server-based nodes that require network / connectivity settings, such as MQTT nodes, are found here if they have been deleted from a flow.
  • You may want to remove these types of unused nodes from the back-end because they may continue to try connecting to a port and degrade performance.
  • Not all deleted nodes appear in the Config tab.
  • When you save a flow or the entire workspace, a pop-up message notifies you if there are unused nodes.
