Entropy

Entropy is a cross-platform Ergohaven application for configuring programmable keyboards and other input devices running Vial-QMK or Vial-RMK firmware

The application combines layout editing, firmware configuration, device testing, and desktop tools in one interface

Compatibility

Entropy works with devices that expose a compatible Vial interface

• Vial-QMK and Vial-RMK

• Bluetooth connections for compatible Vial-RMK devices
• Keyboards, macropads, trackballs, touchpads, encoders, and modular input devices
• Windows x86_64, Linux x86_64, and macOS on Apple Silicon or Intel

The available pages depend on firmware capabilities: Entropy hides settings that the connected device does not support
