Don't we need a daemon reload everytime the file is changed ?

@ipitio we might need a way to replace the current crontab with a systemd timer for existing users.

[ipitio]

All they would have to do is open Speedtest settings and click save* (so it would be updated when they next update settings, giving us time to iron out any bugs), or that could be automated.

*I changed save to confirm as I felt it's more appropriate due to the flush and new chart default and update/uninstall operations.

Todo: use screen, copy modded admin and pihole, check if update/uninstall failed, and if so, move them back and notify user that command(s) failed and to try again or attempt manually

@ipitio how about we add code to remove existing crontab if they save settings and remove it after a few future releases?

That's exactly what it does at the moment! SetService() is (and SetCrontab() was) only called when saving settings.
