Silicon Labs Flasher for Home Assistant (app)

About

Silicon Labs Flasher is an app that flashes firmware onto Silicon Labs based wireless modules. It targets modules reachable through a serial port, such as the one on Home Assistant Yellow, Home Assistant SkyConnect or ZBT-1, and other USB based wireless adapters. The app has access to USB, serial and GPIO devices and can talk to the Supervisor. It requires Home Assistant OS and runs on aarch64 and amd64 systems. It adds no page to the sidebar, and the target device is chosen in the app configuration before it is started.
