i want to track router daily/monthly/yearly bandwith usage in my homeautomation system

is there a possibility to output bwmon stats to a file?
i want something like average down/upload rate for the last minute and accumulated down/upload volume per day
file should not be appended, values should be overwritten every minute.

At the bottom of the bandwidth usage page you can download the data

actually, i need a file to parse, automatically

It already logs to files in /tmp and /usr/data, but you won’t be able to parse them easily (they aren’t human readable).

You can try using the bw_get command to get specific information.

Otherwise you’re out of luck without rewriting it yourself.
Other users have automated the download of the CSV file for similar purposes, but I don’t know exactly how they did it.
