FreeMDU is an open hardware and software project for communicating with Miele appliances through their proprietary optical infrared diagnostic interface, serving as a free alternative to Miele's technician-only MDU software. It includes a Rust protocol library, a terminal-based diagnostic TUI, and adapter firmware with MQTT integration for Home Assistant.
Use cases
- diagnose Miele washing machines and appliances at home
- read error codes from a Miele appliance without a service technician
- integrate Miele appliances into Home Assistant via MQTT
- reverse-engineer the Miele optical diagnostic protocol
- build a DIY infrared adapter for Miele devices
When to choose
- you own a supported Miele appliance and want free diagnostics or home automation integration
- you want an open-source alternative to the proprietary Miele MDU tool and adapter
- you're comfortable with experimental hardware projects and Rust tooling
When to avoid
- you need guaranteed safety - the project warns it can permanently damage devices
- your appliance's software ID is not on the confirmed supported list
- you need a polished, production-ready solution with official support
