A companion utility for Keychron keyboards: a Windows tray battery monitor plus other small features (like firmware flashing). For now, complete features are available on Keychron K10 HE only (USB / 2.4 GHz dongle / Bluetooth). Community project, not affiliated with Keychron.

QMK firmware mod that makes the Keychron K10 HE 'Companion-friendly': reports battery over a custom raw-HID channel (0xA4) - including the 2.4 GHz dongle via a push model - plus the keyboard model id, so the host app can show the model name on any link.
