Auto Logger: log data in daily CSV files

A very simple flow to store your Node-Red data in CSV file, new file every day. The flow will generate a new file for every day automatically. There is also an archiving flow that moves data older than 10 days from your PI to NAS for long term storage. Check the comment nodes for further details.
