Additionally the systemd units I'm using:

# /home/hexa/.config/systemd/user/wirerrd-collect.service

Current issue with that setup is that data collection is not working properly. Instead of data being appended it is being overwritten afaict.

As noted on IRC, not an issue of wirerrd, but an issue of the provided systemd unit file.

If someone could provide a working systemd unit, I'd gladly add it to the contrib folder of wirerrd.
