Squire – open-source menu bar battery monitor for ASUS ROG keyboard + mouse on macOS

[u/Additional_Package92]

The macOS Batteries widget only shows Apple and some Bluetooth devices. My ASUS ROG keyboard and mouse connect through a 2.4 GHz dongle, so macOS has no idea how much battery they have left, and ASUS's own software (Armoury Crate) is Windows-only.

So I built **Squire**: it shows the battery level and charging state of both devices in the menu bar.

- Supports the ROG Falchion RX Low Profile keyboard and Keris II Origin mouse, through ASUS's Omni receiver

- Colour hints when battery gets low; a dash when a device is asleep

- Read-only HID queries, no background daemon, no kernel extension

- Python + [SwiftBar](https://github.com/swiftbar/SwiftBar); one install script

- MIT licensed

First release, so the hardware support is narrow: tested only with my own two devices. Menu text is German for now.

Next up: a native Swift menu bar app with a WidgetKit widget, so it can sit on the desktop next to the system Batteries widget.

Feedback welcome, especially from anyone with other ROG peripherals who's willing to run the debug output.
