Config Web: Web-based Configuration Interface

config_web is a lightweight HTTP service providing a web UI for configuring the Agent's LLM provider, API keys, STT/TTS settings, and other runtime parameters. Changes are persisted to /userdata/agent/agent.toml and can trigger Agent restart.

Default Parameters

Parameter	Default Value
Port	80
Config	/userdata/agent/agent.toml
Binary	/oem/usr/bin/config_web

Startup

/etc/init.d/S56config_web start
/etc/init.d/S56config_web stop
/etc/init.d/S56config_web restart
/etc/init.d/S56config_web reload

The init script supports start, stop, restart, and reload. It does not provide a status command; reload currently performs the same stop-and-start sequence as restart.

Access

Connect the device to your computer via USB-C. The device establishes a USB network at 192.168.42.1. Visit:

http://192.168.42.1

The web interface allows:

• Opening the browser terminal exposed by WeTTY at http://192.168.42.1:3000/wetty/
• Switching the device language between Simplified Chinese (zh-CN) and English (en-US); this also controls user-facing Agent responses and <tts> content
• Switching among registered model provider types such as OpenAI, Anthropic, OpenRouter, Kimi, Volcengine, and Ollama; Google Gemini models are available through compatible providers such as OpenRouter
• Configuring API keys and model names
• Selecting STT/TTS providers
• Testing voice recognition and synthesis
• Restarting the Agent service

The header switch saves only the top-level locale through PUT /api/config/locale. The UI updates immediately and rolls back if persistence fails. The last confirmed value is cached in localStorage for first paint, but GET /api/config remains authoritative. The Agent restart creates a new context session when the locale-specific system prompt changes; it does not rewrite the previous session. locale is intentionally separate from [stt].language, which only configures speech recognition.
