How about a tray icon that displays all wireless Logitech devices and their battery levels. This would save time from opening app to check something this simple. I surf my tray icons for their "behind the scenes" actions results vice opening their respectful apps. If there is a notification mark on the icon then I open the app.

I have the MX ERGO trackball
and G915 keyboard, one simple universal tray icon that polls the battery levels and give notice of attention if needed in the app.
