battery-tray 1.0.0

A system-tray battery monitor with a battery-selection window.

battery-tray

A small Linux system-tray battery monitor, built on sevaht-gui.

• A tray icon shows the selected battery's charge as a colour-graded battery glyph (green → red) with charge/charging state in the tooltip.
• Left-click (or the tray menu's Configure…) opens a window to pick which battery to monitor and set the refresh interval; both are saved under sevaht/battery-tray.
• Desktop notifications (via notify-send) fire when the charge level or charging state changes.
• If no system tray is available, the window simply runs on its own.

Running

$ battery-tray            # start in the tray (window hidden)
$ battery-tray --show     # start with the window open

Configuring from the CLI

These update the saved config and exit (handy for scripts/keybinds); the running app picks the same values up from config:

$ battery-tray --list-batteries       # show detected batteries and exit
$ battery-tray --battery BAT0         # set the monitored battery by name
$ battery-tray --select-battery       # choose interactively from a list
$ battery-tray --set-poll-seconds 10  # set the refresh interval (1-3600s)

Reads battery state from /sys/class/power_supply (Linux only).
