Valetudo is a production-grade, self-contained control web interface for robot vacuums. It replaces vendor cloud services by running directly on the vacuum's embedded Linux hardware and communicating with the robot over reverse-engineered local protocols (MiIO/MIoT for Dreame and Roborock, MSmart for Midea, and 3irobotix for Viomi). The backend is a Node.js/Express application that exposes a REST API with OpenAPI schemas, server-sent events for live state/map/log updates, MQTT integration for Home Assistant and Homie discovery, an updater for over-the-air firmware-style binary updates, timers, consumables, and map management. The frontend is a React/TypeScript SPA with a canvas-based interactive map renderer, manual control, provisioning, timers, updater UI, and configuration pages.
