Fetch data and create a txt

[TheFranz]

Hello,
I write here to find a possible solution to my problem.
I need to fetch data from my Netatmo Weather Station and then create a txt file like this one: https://forum.meteonetwork.it/rete-staz ... 1060754739
I have a server where I could run a Python app, but I don't know where to start from.
Anyone can help me?
Thank you very much.
