🤝: Effortless Setup & Seamless Matter Integration

Key Features of 🤝: Effortless Setup & Seamless Matter Integration?

• Domain-Specific Tooling: Predefined commands for lights, climate systems, locks, alarms, and humidifiers ensure precise control with minimal configuration.
• Environment Variables Simplification: Securely store credentials through a dedicated .env file, reducing manual entry errors.
• Multi-Stage Deployment: Flexible setup options for both rapid prototyping and production-ready environments.
• Developer-Friendly Debugging: Integrated support for the MCP Inspector tool to trace command execution and troubleshoot workflows.

Use cases for 🤝: Effortless Setup & Seamless Matter Integration

This project excels in scenarios where:

• Users want to automate complex home routines (e.g., "Sunset Mode" adjusting lights and temperature).
• Remote access to security systems is required without compromising API security.
• Custom voice commands are mapped directly to Home Assistant's device controls.
• Third-party platforms need standardized access to home climate or energy management systems.

FAQ for 🤝: Effortless Setup & Seamless Matter Integration

Does this require coding expertise?

Basic familiarity with JSON and environment variables is recommended, but most workflows follow straightforward configuration patterns.

Can I integrate non-Matter devices?

Yes! The MCP protocol supports any Home Assistant entity, regardless of hardware standards, provided proper entity IDs are referenced.

How do I handle version updates?

Published releases are backward-compatible, but developers should review CHANGELOG.md for breaking changes before production deployments.

What security measures are included?

Credentials are encrypted at rest, and command execution logs are rate-limited to prevent brute-force attacks.

🤝 Home Assistant MCP Server

A Model Context Protocol (MCP) server project that integrates with Home Assistant to provide smart home control capabilities.

Prompts

The server provides prompts for each domain's set of tools.

Tools

The server implements control for various Home Assistant domains. Currently supports:

• 💡 Lights: Turn on/off, brightness control
• 🌡️ Climate: Temperature control, HVAC modes
• 🔒 Locks: Lock/unlock functionality
• 🚨 Alarm Control Panel: Arm/disarm security systems
• 💧 Humidifier: Humidity control

Example tools include:

light-turn_on()
climate-turn_off()
alarm_control_panel-disarm()
lock-lock()
humidifier-turn_off()

Configuration

Environment Variables

Create a .env file in the root directory with:

HOMEASSISTANT_TOKEN=your_long_lived_access_token_here # get it from your Home Assistant instance after onboarding
HOMEASSISTANT_BASE_URL=your_home_assistant_url_here # e.g. http://homeassistant.local:8123

Quickstart

Install

Follow the instructions on how to install Home Assistant and get a long lived access token.

Development

Building and Publishing

To prepare the package for distribution:

1. Sync dependencies and update lockfile:

uv sync

2. Build package distributions:

uv build

This will create source and wheel distributions in the dist/ directory.

3. Publish to PyPI:

uv publish

Note: You'll need to set PyPI credentials via environment variables or command flags:

• Token: --token or UV_PUBLISH_TOKEN
• Or username/password: --username/UV_PUBLISH_USERNAME and --password/UV_PUBLISH_PASSWORD

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.

You can launch the MCP Inspector via npm with this command:

npx @modelcontextprotocol/inspector uv --directory /Users/miguel/Documents/home-assistant-server/home-assistant-server run home-assistant-server

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
