Weishaupt WEM Portal MCP Server

Control and monitor your Weishaupt heating system with AI assistants via the WEM Portal

Version npm License: MIT Blog Website

MCP TypeScript Node.js semantic-release

Features

Device Discovery - List all devices and modules from your WEM Portal account
Live Parameters - Read temperatures, pressure, operating modes with current values
Full Overview - Get a complete snapshot of your entire heating system in one call
Write Parameters - Adjust target temperatures, operating modes, schedules
Device Status - Check connection status of your devices
Writable Filter - List only the parameters you can actually change
Session Management - Automatic cookie-based auth with login lock for concurrent requests

Quick Start

Install via npx (recommended)

No installation needed. Configure your MCP client to run:

npx @disane-dev/weishaupt-wem-mcp-server

Install from source

git clone https://github.com/Disane87/weishaupt-wem-mcp-server.git
cd weishaupt-wem-mcp-server
npm install
npm run build

Configuration

Claude Desktop

Add to your Claude Desktop config:

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "weishaupt-wem": {
      "command": "npx",
      "args": ["-y", "@disane-dev/weishaupt-wem-mcp-server"],
      "env": {
        "WEM_USERNAME": "[email protected]",
        "WEM_PASSWORD": "your_password"
      }
    }
  }
}

Claude Code

claude mcp add weishaupt-wem -- npx -y @disane-dev/weishaupt-wem-mcp-server

Set the environment variables WEM_USERNAME and WEM_PASSWORD before starting.

From source

{
  "mcpServers": {
    "weishaupt-wem": {
      "command": "node",
      "args": ["/path/to/wem-mcp/build/index.js"],
      "env": {
        "WEM_USERNAME": "[email protected]",
        "WEM_PASSWORD": "your_password"
      }
    }
  }
}

Environment Variables

Variable	Required	Description
`WEM_USERNAME`	Yes	Your WEM Portal email
`WEM_PASSWORD`	Yes	Your WEM Portal password
`WEM_API_URL`	No	API base URL (default: `https://www.wemportal.com/app`)

Available Tools

Tool	Description
`wem_get_devices`	List all devices with modules. Call this first to discover IDs.
`wem_get_device_status`	Get connection status of a device
`wem_get_overview`	Full device overview: all modules with all parameters in one call
`wem_get_parameters`	Get all parameters of a module with current values
`wem_get_parameter_meta`	Get parameter metadata (names, min/max, enums, writable flag)
`wem_get_writable_parameters`	List only adjustable parameters with ranges and options
`wem_read_parameters`	Read specific parameter values by ID
`wem_write_parameter`	Set a parameter value (e.g., target temperature)

[!TIP] Start with wem_get_devices to discover your deviceId, moduleIndex, and moduleType, then use wem_get_overview for a complete snapshot of your heating system.

Typical Workflow

1. wem_get_devices
   -> Returns devices with modules (WE0=heat generator, HZK0=heating circuit, WW0=hot water)

2. wem_get_overview (deviceId)
   -> Returns ALL modules with ALL parameters in one call

3. wem_get_writable_parameters (deviceId, moduleIndex, moduleType)
   -> Shows what you can adjust, with min/max ranges

4. wem_write_parameter (deviceId, moduleIndex, moduleType, parameterId, numericValue)
   -> Sets a writable parameter (e.g. target temperature)

Common Module Types

Type	Name	Description
1	SYSTEM	System overview
2	HZK	Heating circuit (temperatures, operating mode)
3	WW	Hot water (temperature, push, schedule)
5	TERMINAL	Control panel
6	GATEWAY	Communication gateway
7	WE	Heat generator (boiler/heat pump performance)
9	Device	Physical device unit
10	GROUND	Ground module

Development

Command	Description
`npm run build`	Build the project
`npm run watch`	Watch mode (auto-rebuild on changes)
`npm start`	Run server directly
`npm test`	Test API connection
`npm run inspector`	Official MCP Inspector (Web UI)
`npm run inspector:cli -- devices`	CLI inspector for quick API tests

Troubleshooting

[!NOTE] Make sure you can log in at wemportal.com before using this server.

Issue	Solution
Authentication failed	Verify credentials, check if WEM Portal blocks after too many attempts
Connection timeout	Check internet, WEM Portal may be temporarily unavailable (30s default timeout)
Parameter values show 0	Some parameters (e.g. room temperature) require a physical sensor connected to the device
