Export data to realtime.txt

[cojka80]

Hi all,
we are novice with Meteohub and therefore we appologize for asking a dumb question.
Can someone please help us with exporting data to realtime.txt and send it to ftp.
We need basic setup quide for this.
Here are information of Metehub:

Linux Kernel: 4.4.27+ 697 BogoMIPS, 445 MB RAM, Raspberry PI Model B
MeteoHub: 5.0s (Build 180)

Thanks in advance.
