MiGPT Xiaomi Assistant

Deploy MiGPT on a Xiaomi smart speaker to replace the built-in AI with a custom LLM-powered voice assistant. Use when: (1) setting up mi-gpt on a Xiaomi/Redmi speaker, (2) troubleshooting MiNA vs MIoT TTS issues, (3) fixing Xiaomi account security verification loops, (4) optimizing voice assistant response latency, (5) configuring wake words and trigger keywords for mi-gpt. Covers X08E and other speaker models. NOT for: Google Home, Alexa, or non-Xiaomi smart speakers.

MiGPT Xiaomi Voice Assistant Deployment

Deploy mi-gpt v4.2.0+ on a Xiaomi smart speaker to replace the built-in AI with a custom LLM assistant.

Prerequisites

• Node.js >= 18
• Xiaomi account with a supported smart speaker
• An OpenAI-compatible LLM API (DashScope, DeepSeek, OpenRouter, etc.)

Quick Start

1. Initialize project

mkdir -p ~/projects/mi-gpt && cd ~/projects/mi-gpt

Create package.json:

{
  "type": "module",
  "dependencies": { "dotenv": "^17.0.0", "mi-gpt": "^4.2.0" }
}

npm install

2. Create files

app.js:

import "dotenv/config";
import config from "./.migpt.js";
import { MiGPT } from "mi-gpt";
const client = MiGPT.create(config);
await client.start();

.env:

OPENAI_MODEL=your-model
OPENAI_API_KEY=sk-xxx
OPENAI_BASE_URL=https://your-api-endpoint/v1

.migpt.js — See references/config-template.md for full template with comments.

3. Find your device's MIoT commands

Different speaker models use different MIoT siid/aiid values. Look up your model in mi-gpt issues or the MIoT spec.

Common values:

Model	ttsCommand	wakeUpCommand	streamResponse
X08E (Redmi 8寸)	[7, 3]	[7, 1]	false
LX04	[5, 1]	[5, 3]	true
L05C	[5, 1]	[5, 3]	true
LX06	[5, 1]	[5, 3]	true
L09A	[5, 1]	[5, 3]	true

4. Run

nohup node app.js > migpt.log 2>&1 &

Critical Issues & Fixes

Issue 1: MiNA TTS returns success but no audio (X08E and some models)

Symptom: mina.play({tts: '...'}) returns true but speaker stays silent.

Cause: Some models (notably X08E) don't support MiNA's ubus mibrain/text_to_speech. They require MIoT's doAction.

Fix: Ensure ttsCommand is set correctly. MiGPT will use MIoT doAction(siid, aiid, text) when ttsCommand is configured.

Issue 2: MIoT login triggers security verification every time

Symptom: securityStatus: 16 on every startup, even after completing SMS verification multiple times.

Root cause: mi-service-lite generates a random deviceId on every startup → Xiaomi treats each login as a new device → perpetual verification loop.

Fix: See references/miot-auth-bypass.md for the browser cookie injection method.

Issue 3: streamResponse causes hang on some models

Symptom: MiGPT says "让我想想" then freezes.

Cause: streamResponse: true polls MiNA.getStatus() for playback state. On models where MiNA doesn't control the speaker (e.g., X08E), status always returns "paused", causing the poll loop to malfunction.

Fix: Set streamResponse: false. If you also need keepAlive (continuous conversation) mode, patch enterKeepAlive() in node_modules/mi-gpt/dist/index.js to remove the streamResponse check. See references/patches.md.

Issue 4: Native 小爱 AI races with custom AI

Symptom: Both 小爱 and your custom AI respond to the same query ("split personality").

Mitigations (pick one or combine):

1. Set onAIAsking: ["嗯"] — immediately interrupts 小爱 with a short TTS
2. Disable voice reply in 小爱 App (device settings → 语音回复 → off)
3. Use 全量接管模式: callAIKeywords: [""] — responds to all queries

Issue 5: Wake word misrecognition

Symptom: 小爱's ASR mishears custom keywords (e.g., "花卷卷" → "花姐姐").

Fix: Add common misrecognition variants to callAIKeywords and wakeUpKeywords.

LLM Model Selection

For voice assistants, latency > intelligence. Test your API endpoint:

time curl -s --max-time 15 YOUR_BASE_URL/chat/completions \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"MODEL","messages":[{"role":"user","content":"一句话回答：今天星期几"}],"max_tokens":30}'

Target: < 3 seconds for acceptable voice experience. Total end-to-end latency ≈ LLM time + 3-4s (polling + MIoT overhead).
