e.g on inject node edit the repeat option
e.g on read timeseries node on topic choose an asset, variables and period - Connect the nodes to create a flow
- Save your creation
- Trigger data to the flow with the inject node
- Check the debug tab to visualize the results
The messages displayed in the debug window can be filtered using the filter button.
Add a function and filter node with an email sender
Drag and drop between the time series node and the debug node
A function node
- Double click on the node to edit properties
- Edit the name of the function and on the code window write in Javascript a simple function
- On the code block window below copy the entire text
The function reads the last value on the string. On this case the Current last value

The orange border indicates that the node is selected
The blue circle identifies nodes that have not yet been saved
The red triangle indicates missing inputs or errors in the node properties
The text below the node shows status and error messages
