Once you click the Go To Flow Definition icon for a Flows Manager, you can manage the flow canvas.

You can search for individual nodes by using the search bar.

There are several options available when deploying a flow. The options in the Deploy drop-down list indicate the type of save that is currently active for a deploy action.

Open the menu in the top-right corner to view options for the flow canvas.

Importing nodes allows you to easily deploy flow logic for a variety of devices and use cases.

The import operation relies on a previous export to the library, download, or clipboard copy. Using import from the menu offers three tabs: Clipboard, Local, and Examples.

The Clipboard tab provides a way to paste code saved to the clipboard or select a JSON file from your hard drive to import. To import a JSON file saved from a previous export, use the Library tab.

You can import the nodes from the following ways:

After selecting the nodes to import, select if the import should go to the current flow or a new flow. When you import to a new flow, the system automatically creates a new flow tab and displays the nodes and wires freely so you can place them in the new flow.

Exporting nodes allows you to download a file of flows.

Using Export from the menu offers two tabs: Clipboard and Local.

The Clipboard tab temporarily saves node data to the clipboard. To save node data for a longer term, use the Library tab.

You can export one or more nodes and their connecting wires and then paste them to a flow.

Select the nodes and connecting wires within a flow tab.

[1] Select if you want to export selected nodes, the current flow, or all flows.

[2] Select to view the nodes in list view or in JSON format. If you view in JSON format, you have the option of viewing the code in compact or formatted style.

Selecting Configuration nodes opens the Config tab 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. To view unused nodes, click unused to filter the nodes displayed. 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.

Subflows serve as sub-routines to place complex logic into code blocks, which then can be called from the main flow. As with any structured programming language, this modular approach simplifies troubleshooting, modifications, and basic understanding.

You have two options for creating a subflow.

To create a subflow, select Subflows > Create Subflow.

To create a subflow from an existing flow, drag and select the nodes to include, and then select Subflows > Selection to Subflow.

Use the flow tabs menu to add new tabs, manage existing tabs, and show/hide tabs.

Click the + icon to add a new tab.

Review the following additional options for the flow canvas.

[1] Toggle the navigator to navigate the entire canvas. Also zoom in and out of the canvas.

[2] Info: Review information for flows.

[3] Help: Search help for using the canvas and flows.

[4] Debug messages: Review debug messages for flows that are running.

[5] Configuration nodes: See the "Configuration Nodes" section above.

[6] Context Data

[7] Dashboard: The Flows dashboard allows you to visualize data and information pertaining to your flows. You can organize the dashboard into tabs and groups, and then add widgets and links to display specific information. You can then make aesthetic choices for the look and feel of your dashboard.

The following tabs allow you to customize how you view the data.
