A sample conversation with Claude AI can be viewed here

Prerequisites

1. Modbus TCP connection to the LG Therma V heat pump. (such as Waveshare)
2. A MCP client, such as Claude Desktop

Installation

1. Grab the binary for your system from the releases page.
2. Unzip the binary and optionaly place it into your path.
3. Make sure the binary is executable. On Linux and Mac, you can do this by running chmod +x lg-thermav-mcp-server.

Usage with Claude Desktop

1. Copy the file claude_desktop_config.json to Claude Desktop config directory.
   • On Mac, this is usually /Library/Application\ Support/Claude/claude_desktop_config.json
   • On Linux, this is usually ~/.config/Claude/claude_desktop_config.json
   • On Windows, this is usually AppData\Claude\claude_desktop_config.json
2. Open the claude_desktop_config.json file and change "command":"<path to lg-thermav-mcp-server>" to the path of the lg-thermav-mcp-server binary.
3. Open the claude_desktop_config.json file and change "MODBUS_URL": "<modbus-url>" to the URL of your modbus TCP connection. For example, tcp://192.168.1.10:4196
4. Open Claude Desktop and start a new conversation. You should see available LG Therma V tools if everything is set up correctly.
