Hi @jagades you can use the write file node to write msg.payload to a file, also you can format it with CSV or JSON node to save temperature vs time.
The best way to do this depends on what you want to do with the data later.
You should consider using a database if you want to further use the data. Dashboard can also be used effectively to 'look' at the historical data.
Great! @jagades You could use a CSV or JSON node to format, before to send to write file node. But I think your main problem was solved (Save dashboard chart in an external file).
