- Home Assistant long-lived access token
If you're using an older version of Node.js, you can use `nvm` (Node Version Manager) to install and use the correct version:
### Basic Installation
```bash
# Install nvm (if not already installed)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
# Reload shell configuration
source ~/.bashrc # or source ~/.zshrc for Zsh
# Install Node.js 20.10.0
nvm install 20.10.0
# Use Node.js 20.10.0
nvm use 20.10.0
```
## Installation
### Classic Installation
```bash
# Clone the repository
git clone https://github.com/jango-blockchained/homeassistant-mcp.git
cd homeassistant-mcp
# Install dependencies
npm install
# Build the server
npm run build
```
### Docker Installation
#### Using Docker Compose (Recommended)
1. Clone the repository:
```bash
git clone https://github.com/jango-blockchained/homeassistant-mcp.git
cd homeassistant-mcp
```
2. Create a `.env` file with your Home Assistant configuration:
```env
NODE_ENV=production
HASS_HOST=your_home_assistant_url
HASS_TOKEN=your_home_assistant_token
```
3. Start the container:
```bash
docker-compose up -d
```
#### Using Docker Directly
1. Build the image:
```bash
docker build -t homeassistant-mcp .
```
2. Run the container:
```bash
docker run -d \
--name homeassistant-mcp \
-e HASS_HOST=your_home_assistant_url \

3. **MCP Client Configuration**
Configure your MCP client (like Claude Desktop) with:
```json
{
"mcpServers": {
"homeassistant": {
"command": "node",
"args": [
"/path/to/dist/index.js"
],
"env": {
"HASS_TOKEN": "your_home_assistant_token",
"HASS_HOST": "your_home_assistant_url"
}
}
}
}
```
## How to Use
The server provides two main tools for interacting with Home Assistant:
### 1. List Devices Tool
Use this tool to discover all available devices and their current states:
## Usage Guide
### Device Discovery
```json
{
"tool": "list_devices"
}
```
This will return a structured response with all devices grouped by domain:
### Basic Controls
```json
{
"success": true,
"devices": {
"light": [
{
"entity_id": "light.living_room",
"state": "on",
"attributes": {
"brightness": 128,
"color_temp": 4000,

}
}
],
"climate": [
{
"entity_id": "climate.bedroom",
"state": "heat",
"attributes": {
"temperature": 22,
"hvac_mode": "heat",
"friendly_name": "Bedroom Thermostat"
}
}
]
}
}
```
### 2. Control Tool
Use this tool to control your devices. Here are some common usage examples:
#### Light Control
```json

"entity_id": "switch.office"
}
// Toggle
{
"tool": "control",
"command": "toggle",
"entity_id": "switch.office"
}
```
### Error Handling
The server provides clear error messages when something goes wrong:
```json
{
"success": false,
"message": "Failed to execute set_temperature for light.living_room: Unsupported operation for domain: light"
}
```
Common error scenarios:
1. Invalid entity ID
2. Unsupported operation for domain
3. Invalid parameter values
4. Home Assistant connection issues
### Best Practices
1. **Entity Discovery**
- Always use `list_devices` first to discover available entities
- Note the supported attributes for each device
2. **Parameter Validation**
- Brightness: 0-255
- Position/Tilt: 0-100
- Temperature: Depends on your system's configuration
- Color temperature: Typically 2000-6500K
3. **Error Recovery**
- If a command fails, check:
- Entity ID exists and is correct
- Command is supported by the domain
- Parameters are within valid ranges
4. **State Awareness**
- Use `list_devices` to check current state before making changes
- Verify command execution by checking state afterward
### Smart Features
- Context awareness across conversations
- Natural parameter interpretation
- Intelligent error prevention
- Multi-device orchestration
## Development
```bash
# Run in development mode
yarn dev
# Build and start
yarn build:start
# Run tests
yarn test
npm run dev # Development mode
npm run build # Build project
npm test # Run tests
```
## Troubleshooting
### Common Issues
1. **Node.js Version Error (`positive.toSorted is not a function`)**
- This error occurs when using Node.js version lower than 20
- Solution: Update to Node.js 20.10.0 or higher using nvm (see Prerequisites section)
- Docker users: The container automatically uses the correct Node.js version
2. **Connection Errors**
- Verify your Home Assistant instance is running
- Check the HASS_HOST is correct and accessible
- Ensure your token has the required permissions

## Using with LLMs (AI Assistants)
The MCP server is designed to work seamlessly with AI language models. Here's how to interact with your Home Assistant using natural language:
### Natural Language Examples
1. **Discovering Devices**
```
"What devices do I have in my home?"
"Show me all my lights"
"List the climate controls in the bedroom"
```
The LLM will use the `list_devices` tool to fetch and present this information in a human-readable format.
2. **Basic Controls**
```
"Turn on the living room lights"
"Set the bedroom temperature to 22 degrees"
"Close all the blinds"
```
The LLM will translate these commands into appropriate tool calls using the `control` tool.
3. **Complex Operations**
```
"Make the living room cozy for movie night"
→ LLM might:
- Dim the lights (set brightness to 30%)
- Set warm color temperature
- Lower the blinds
- Adjust the temperature
"Set up my morning routine"
→ LLM might:
- Open the bedroom blinds
- Turn on specific lights
- Adjust the thermostat
```
4. **State-Aware Commands**
```
"Is my front door closed?"
"Which lights are currently on?"
"What's the temperature in the bedroom?"
```
The LLM will check current states using `list_devices` before responding.
### Context and Memory
The LLM can maintain context across multiple interactions:
```
User: "How warm is it in the bedroom?"
LLM: [checks temperature] "The bedroom is currently 20°C"
User: "Make it a bit warmer"
LLM: [remembers context, adjusts by reasonable increment] "I'll increase it to 22°C"
```
### Natural Parameter Handling
The LLM can interpret natural language into specific parameters:
```
"Make the lights very dim" → brightness: 10%
"Set a comfortable temperature" → temperature: 21-23°C
"Change the lights to a warm color" → color_temp: ~2700K
```
### Intelligent Error Prevention
The LLM will:
1. Validate commands before execution
2. Check device capabilities
3. Ensure parameters are within acceptable ranges
4. Provide helpful feedback if a command can't be executed
Example:
```
User: "Set the kitchen light to blue"
LLM: [checks if the light supports RGB]
- If supported: Sets rgb_color to [0, 0, 255]
- If not supported: "I'm sorry, but your kitchen light doesn't support color changes. I can only adjust its brightness."
```
### Best Practices for LLM Interactions
1. **Be Specific with Locations**
- Good: "Turn on the kitchen lights"
- Better: "Turn on the lights above the kitchen counter"
2. **Use Natural Increments**
- "Make it a little brighter" → +20% brightness
- "Make it much warmer" → +3-4°C
3. **Group Related Commands**
```
"Set up the living room for watching TV:
- Dim the lights to 20%
- Set them to a warm color
- Lower the blinds
- Set the temperature to 22 degrees"
```
4. **Ask for Confirmation**
```
User: "Turn off all lights"
LLM: "I'll turn off all 12 lights in your home. Would you like me to proceed?"
```
### Handling Complex Scenarios
1. **Conditional Commands**
```
"If the temperature is above 25°C, turn on the fan"
→ LLM will:
1. Check current temperature
2. Execute command if condition is met
```
2. **Time-Based Context**
```
"Set up my evening lighting"
→ LLM considers:
- Time of day
- Current light levels
- User preferences
```
3. **Multi-Room Coordination**
```
"Prepare the house for bedtime"
→ LLM orchestrates:
- Turning off main living area lights
- Dimming hallway lights
- Setting night mode temperatures
- Ensuring doors are locked
```
### Troubleshooting with LLMs
The LLM can help diagnose issues:
```
User: "The living room lights aren't responding"
LLM: Let me check:
1. Verifies device availability
2. Checks current state
3. Reviews recent commands
4. Suggests potential solutions
```
### Security Considerations
1. **Confirmation for Critical Actions**
- The LLM will ask for confirmation before:
- Controlling security devices
- Making large temperature changes
- Executing commands affecting multiple devices
2. **Permission Awareness**
- The LLM respects device permissions
- Provides clear feedback when actions aren't permitted
