Script to collect visitor data from the FLASHH boulder spot in Hamburg, Germany.
This all works with CSV files of the following format:
date;stays
10:00;23
10:05;31
10:10;29
...
The flashh-plot.gnuplot file requires a flashh-plot.csv file and renders its content to a flashh-plot.png file.
The flashh-stays.sh loads the data from the server and writes it into a CSV file with a name like flashh-stays_2020-10-25.csv.
After that it takes this CSV file, copies it, renders it using the gnuplot script and renames the PNG file into flashh-stays_2020-10-25.png.
The flashh-stays.timer and flashh-stays.service are config files to a systemd timer executing the flashh-stays.sh file every 5 minutes between 8AM and 11:59PM.
