batalert

Send D-Bus notifications when the (Linux) host's battery runs low.

Prerequisites

• Install libnotify
• Install a Notification Server to render desktop notifications
  • Use mako on Wayland/Sway setups

Usage

You can run batalert with default setting to send the first notification when the battery falls below 15% and repeat the notification every 3%. batalert resets when you plug-in your charger.

Customization

• Check the help text:

  batalert -h
  

• Show a notification when the battery falls below 20%, repeat notification every 4% on 16%, 12%, 8% ... :

  batalert --threshold 20 --notification-step 4
  

• Use a custom icon:

  batalert --icon /usr/share/icons/<your-icon>.png
  

• Monitor a certain battery, e.g., BAT2:

  batalert --uevent /sys/class/power_supply/BAT2/uevent
