Replying to an earlier post

You can configure Keychron peripherals via their website - Keychron Launcher.

It works on Linux, but there are two caveats:

  1. Requires Chromium web browser. I’ve tested it with Ungoogled Chromium and it worked fine.
  2. In some Linux distributions you will have to set up udev rules, to allow access to USB devices

I’ve tested it with my Keychain K3 keyboard and M4 mouse and it works.

I agree a compatibility with ex. Piper would be neat though
