Executing Python scripts based on node templates
I was searching for documentation on how to write a Python script using the template node and executing that script with the exec node.
This flow is an example of that - using only built in Node-RED nodes.
I would have liked to skip the part, where I am writing the file to disk - but I was unable to get this result, when running the exec node in spawn mode.
