What it does

MiGPT hijacks Xiaomi’s Xiao AI smart speakers and swaps out the stock voice assistant for ChatGPT, Doubao, or other LLMs. You get AI Q&A, role-play personas, streaming responses, conversation memory, and custom TTS voices — all triggered by the usual “Xiao Ai” wake word. Runs via Docker or Node.js with a config file and your Xiaomi account credentials.

The interesting bit

The project treats the speaker as a dumb I/O endpoint and pipes everything through a proper LLM backend, effectively turning a walled-garden IoT device into an open-ended conversational agent. The “Agent” features for smart-home automation are crossed out in the README, suggesting the vision outran the implementation.

Key highlights

• Supports most Xiao AI speaker models; Pro recommended for “perfect” operation
• Docker one-liner or NPM package for Node developers
• Custom TTS via Doubao voices (or third-party providers)
• Long/short-term memory for multi-turn conversations
• Active ecosystem: GUI config tools, video tutorials, community forks including one with camera support

Caveats

• Explicitly unmaintained: the README opens with a warning that updates and support have ended
• No support for Baidu, Tmall Genie, HomePod, or non-Xiaomi speakers
• Smart-home “Agent” automation features appear abandoned (struck through in docs)
• Requires handing over Xiaomi account credentials to a third-party service

Verdict

Grab the code if you already own a Xiao AI speaker and want to tinker with LLM voice interaction without buying new hardware. Skip it if you need ongoing maintenance, security guarantees, or don’t speak Chinese — the docs, tutorials, and voice interfaces are Mandarin-first.
