My own personal swaybar implementation.

Implements the swaybar protocol for use in sway.

• work time / break reminder : gently reminds me to stand up and get away from the screen after a set period of time (uses the wayland protocol org_kde_kwin_idle to get the idle timeouts).
• battery usage
• current date/time
• connected wifi

maybe? If you don't have the same battery setup as me (i.e. the same layout in /sys/class/power_supply/) then probably not.
