Homey MCP Server

This is an MCP server for Homey (by Athom) that allows AI agents to control smart home devices, trigger flows, and query zones.

Prerequisites

• Homey Pro or Homey Cloud
• Homey Personal Access Token (API Key). You can create one in the Homey Web App under Settings → API Keys.

Installation

1. Clone or copy this directory.
2. Run npm install.
3. Create a .env file based on .env.example:

   HOMEY_TOKEN=your_token_here

Usage

Connecting with Claude Desktop

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "homey": {
      "command": "node",
      "args": ["/Users/XX/.gemini/antigravity/scratch/homey-mcp/index.js"],
      "env": {
        "HOMEY_TOKEN": "YOUR_TOKEN_HERE"
      }
    }
  }
}

Connecting with ChatGPT Desktop

ChatGPT (macOS/Windows) supports MCP servers via Developer Mode.

1. Open ChatGPT Desktop.
2. Go to Settings → Apps → Advanced settings.
3. Enable Developer Mode.
4. Click Create app (or "Add App") and configure a connection:

• Name: Homey
• URL: http://localhost:3000 (if running locally as an HTTP/SSE server) or use the Claude-style local command if supported in your version.

[!NOTE] ChatGPT currently primarily supports MCP over SSE (HTTP). To use this as a local command-line tool like in Claude, you may need a bridge or for ChatGPT to fully roll out stdio support.

Connecting with ChatGPT (Web/Custom GPTs)

To use Homey MCP in the ChatGPT web interface:

1. You must host this MCP server on a public URL (e.g., via ngrok or a VPS).
2. Use the Actions feature in a Custom GPT to connect to your MCP server's OpenAPI spec or SSE endpoint.

Troubleshooting

"HomeyAPI.createCloudAPI is not a function"

This usually happens if the Personal Access Token is used without a HOMEY_IP. Ensure you provide HOMEY_IP for Homey Pro local connections. For Homey Cloud, Ensure your token is valid and specifically created for the Web API.

Connection Closed / MCP Error

If the server fails to connect to Homey, it will now start gracefully but return an error message when you try to use a tool. Check the console logs (stderr) for the specific connection error.

Environment Variables

If running via Claude Desktop, ensure the env section in your config contains the correct HOMEY_TOKEN and optionally HOMEY_IP.
