smarthomeharmonizer 0.1.0

A GenAI assistant-enabled Python framework for bridging IoT devices with voice assistants

SmartHomeHarmonizer

A lightweight Python framework for bridging IoT devices with voice assistants (Amazon Alexa, Google Assistant, and Apple HomeKit).

🎯 Overview

SmartHomeHarmonizer simplifies the integration of custom IoT devices with popular voice assistants by providing:

• Unified API: Single RESTful interface for all voice assistant platforms
• Modular Architecture: Easy-to-implement device adapters
• Lightweight Design: Minimal resource footprint suitable for Raspberry Pi
• Platform Agnostic: Works with Alexa, Google Assistant, and HomeKit
• Research Friendly: Designed for experimentation and education

🚀 Quick Start

Installation

pip install smarthomeharmonizer

Basic Usage

from smarthomeharmonizer import create_app, DeviceManager
from smarthomeharmonizer.adapters.smart_light import SmartLightAdapter

# Create device manager
manager = DeviceManager()

# Register a smart light
light = SmartLightAdapter('light1', 'Living Room Light')
manager.register_device(light)

# Create Flask app
app = create_app(manager)

# Run the server
if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)

Control Your Device

# Turn on the light
curl -X POST http://localhost:5000/api/v1/devices/light1/command \
  -H "Content-Type: application/json" \
  -d '{"command": "turnOn"}'

# Set brightness
curl -X POST http://localhost:5000/api/v1/devices/light1/command \
  -H "Content-Type: application/json" \
  -d '{"command": "setBrightness", "parameters": {"brightness": 75}}'

# Get device state
curl http://localhost:5000/api/v1/devices/light1/state

🛠️ Creating Custom Device Adapters

from smarthomeharmonizer.adapters.base import DeviceAdapter
from typing import Dict, Any, List, Optional

class MyCustomDeviceAdapter(DeviceAdapter):
    """Adapter for my custom IoT device."""
    
    def _initialize_state(self) -> Dict[str, Any]:
        return {
            'power': False,
            'mode': 'auto'
        }
    
    def get_supported_commands(self) -> List[str]:
        return ['turnOn', 'turnOff', 'setMode', 'getStatus']
    
    def execute_command(self, command: str, parameters: Optional[Dict[str, Any]] = None) -> Dict[str, Any]:
        if command == 'turnOn':
            self._state['power'] = True
        elif command == 'turnOff':
            self._state['power'] = False
        elif command == 'setMode':
            mode = parameters.get('mode', 'auto')
            if mode in ['auto', 'manual', 'eco']:
                self._state['mode'] = mode
            else:
                raise ValueError(f"Invalid mode: {mode}")
        
        return self.get_state()
