Requirements

• Fibaro Home Center 3: A running HC3 system with network access
• VS Code: Version 1.103.0 or higher
• Network Access: Your VS Code environment must be able to reach your HC3 system
• HC3 User Account: Valid username and password for your HC3 system

Installation & Setup

1. Install the Extension:
   • Install from VS Code Marketplace (coming soon)
   • Or install from .vsix file using Extensions: Install from VSIX... command

Configuration

Method 1: VS Code Settings (Recommended)

1. Configure via Command Palette:

   • Open Command Palette (Cmd+Shift+P / Ctrl+Shift+P)
   • Run HC3 MCP: Configure Fibaro HC3 Connection
   • Follow the prompts to enter your HC3 details

2. Manual Settings:

   • Go to VS Code Settings
   • Search for "HC3 MCP"
   • Configure:
     • Host: IP address of your HC3 (e.g., 192.168.1.57)
     • Username: Your HC3 username
     • Password: Your HC3 password
     • Port: HC3 port (default: 80)

Method 2: Environment Variables (Fallback)

Create a ~/.env file in your home directory with:

HC3_URL=http://192.168.1.57
HC3_USER=your_username
HC3_PASSWORD=your_password

Note: The extension will automatically use environment variables as fallback if VS Code settings are not configured.

Testing Your Configuration

• Run HC3 MCP: Test Fibaro HC3 Connection command
• Verify successful connection to your HC3 system

GitHub Copilot Configuration

For GitHub Copilot to use the MCP server, you need to configure it manually:

1. Open User Settings (JSON) in VS Code:

   • Press Cmd+Shift+P / Ctrl+Shift+P
   • Type "Preferences: Open User Settings (JSON)"

2. Add MCP Server Configuration:

{
  "github.copilot.chat.experimental.mcpServers": {
    "hc3-smart-home": {
      "command": "node",
      "args": ["/path/to/your/extension/out/mcp/hc3-mcp-server.js"],
      "env": {
        "FIBARO_HOST": "192.168.1.57",
        "FIBARO_USERNAME": "admin",
        "FIBARO_PASSWORD": "your_password",
        "FIBARO_PORT": "80"
      }
    }
  }
}

3. Replace the configuration values:

   • Update the path to your compiled MCP server
   • Set your HC3 IP address, username, and password
   • Restart VS Code

4. Test in Copilot Chat:

   • Important: Start a new chat session after configuring the extension
   • "List my HC3 devices"
   • "@hc3-smart-home get all devices"

Note: If the MCP server tools are not immediately available, start a new GitHub Copilot chat session to allow it to discover the MCP server.

Security Considerations

• Local Network: This extension communicates with your HC3 system over your local network
• Credentials: Passwords are stored in VS Code's secure credential store
• API Access: The extension uses HC3's REST API with standard HTTP Basic Authentication
• No Cloud: All communication is direct between VS Code and your HC3 system

Troubleshooting

Connection Issues

1. Verify HC3 System: Ensure your HC3 is powered on and accessible on the network
2. Check Network Settings: Verify IP address, port, and network connectivity
3. Test Credentials: Ensure username/password are correct and user has API access
4. Test Connection: Use the "HC3 MCP: Test Fibaro HC3 Connection" command to verify settings

Configuration Issues

1. VS Code Settings: Check that all required fields are filled in VS Code settings
2. Environment Variables: If using ~/.env, ensure the file exists and has correct format:

   HC3_URL=http://192.168.1.57
   HC3_USER=admin
   HC3_PASSWORD=your_password

3. File Permissions: Ensure ~/.env file is readable
4. Restart Required: Restart VS Code after changing ~/.env file

MCP Server Issues

1. Check Extension Activation: Verify the extension is enabled and activated
2. Check Output Panel: Look for error messages in VS Code Developer Console
3. Verify MCP Registration: Ensure the MCP server appears in AI assistant settings
4. Restart VS Code: Sometimes a restart resolves registration issues

Common Error Messages

• "Fibaro HC3 not configured": Configure settings or check ~/.env file
• "Connection refused": Check network connectivity and HC3 system status
• "Authentication failed": Verify username and password
• "HTTP 404": Check HC3 firmware version and API availability
• "Configuration incomplete": Ensure all required settings are provided

Known Issues
