Connecting flows using a link node

You can connect two flows indirectly to create flows across different tabs or to break a large flow into smaller ones.

  1. Open Node-RED.
  2. Add nodes to the workspace and connect them to flows.
  3. Add a link node from the output category to the tab with the first flow.
  4. Connect the input of this link node to the output of the last node of the first flow.
  5. Add a link node from the input category to the tab with the second flow.
  6. Connect the output of this link node to the input of the first node of the second flow.
  7. Double-click one of the link nodes to open the Edit node dialogue.
  8. Select the check boxes of the link nodes you want to connect to. A link node can be connected to multiple nodes of the complementary type.
  9. Click Done to apply your changes.
  1. The link nodes connect the flow. Upon selecting a link node, dashed lines hint at the connection.
