🚀 Implementation Solution
Hello everyone! Today I bring you a super cool way to play! Let the AI model ‘Xiaozhi’ directly control your Mi speakers and smart devices!
🎯 Core Features
- Deep Integration: Not just simple conversation, but deep integrated control
- MCP Plugin: Encapsulates Mi speaker’s voice broadcast and device control as MCP server
- Smart Interaction: AI model learns to directly call hardware interfaces
🔧 Technical Implementation
MCP (Model Context Protocol) Simply put, it’s like installing a ’new skill card’ for the AI model ‘Xiaozhi’. I registered the two ‘skills’ of Mi speaker (voice broadcast, device control) as plugins. When Xiaozhi chats with you, once it determines that these skills are needed, it will automatically call the corresponding interfaces!
To implement this MCP, the main work completed includes:
- Deep Integration with Mi Home Platform: Enable the MCP server on ESP32 to stably control Mi Home devices and call Mi TTS
- Build MCP Plugin Interface: Define standard ways for Xiaozhi to understand and call
- ESP32 Firmware Development: Run all this on this cost-effective microcontroller
What does this mean? You have an AI-driven smart home control hub! Xiaozhi’s understanding and decision-making capabilities directly act on your physical world!
🎬 Demo Effects
Talk is cheap, let’s see the actual effects:
Device Query Demo
- Command: “Hello Xiaozhi, what devices are online at home?”
- Result: Xiaozhi’s chat interface displays query results, for example: ‘Detected living room lamp and bedroom air conditioner online.’
Device Control Demo
- Command: “Help me turn on the living room lamp, brighter and warmer.”
- Result: Living room lamp lights up, adjusted to brighter, warm light state
Voice Broadcast Demo
- Command: “Let Mi speaker say: ‘Hello everyone, this is Yang Yang Programming channel, long time no see!’”
- Result: Mi speaker clearly broadcasts: ‘Hello everyone, this is Yang Yang Programming channel, long time no see!’
See that? One sentence, Xiaozhi understands the intention, calls MCP plugin, ESP32 executes, device responds! This is true smart interaction!

How to Get Xiaozhi MCP Key
ESP32 Device Network Configuration
After flashing the firmware, a WiFi hotspot called “Yang Yang Programming” will appear. Normally, a WiFi configuration page will automatically pop up. You can enter the device key and WiFi password for network configuration.
Network Configuration Reference Video: https://www.bilibili.com/video/BV1xa411r7Yj?t=0.3
In addition to network configuration, you also need to log in to your Xiaomi account to complete Xiaomi platform device authorization, as follows:
Open http://homeassistant.local:8123 in a browser on your computer. If this URL cannot be opened, or if there are other Home Assistant devices at home, you can turn off other devices and try again. If it still doesn’t work, you need to manually configure the host in your operating system to point the domain homeassistant.local to the ESP32’s IP address, as shown below:
If you haven’t logged in before, you’ll be asked to enter your account and password to log in; if you have logged in before, just click confirm authorization.
⚠️ Notes
Due to different devices requiring specific parameters for connecting to Mi speaker interfaces, the current test coverage may not include many device types. If you encounter situations where commands don’t execute, it might be that your device model is not yet supported. You can provide feedback on device types in the comments below, and I’ll quickly adapt and update!
FAQ
