batnotify

Notification script and systemd timer for triggering low battery notifications.

How it works

We query battery state and charge percentage using upower. If the battery state is "discharging" and the current charge percentage is less than the specified ${SAFE_BATTERY_LEVEL}, we trigger a notification using notify-send

Now we run the script using a systemd service file. In order to repeatedly check the status, we run a systemd timer for the corresponding service file.
