SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and assets (resource) components.

What problem does it solve?

This skill solves the need for a quick, local demo of how an ESP-based device can serve a simple web page and react to browser input without writing a full application from scratch.

Core Features & Use Cases

  • HTTP server demo with a browser UI: Serve a Hello World page with a toggle switch backed by Lua handlers.
  • Live state and event logging: Use GET to read state and POST to toggle it, with Lua logging switch toggle events.
  • Static web assets on device: Mount the skill-provided web assets so the browser can load CSS/JS and interact with the device.

Quick Start

Start the bundled Lua HTTP server script, then open /lua/lua_demo/ in your browser to view the Hello World page and toggle the switch while it logs events.
