System Implementation

The system uses MQTT for device communication and time-series database for sensor data:

# IoT device manager
class DeviceManager:
    def __init__(self, mqtt_broker: str):
        self.mqtt_client = mqtt.Client()
        self.devices = {}

    def register_device(self, device_id: str, device_type: str):
        topic = f"home/{device_type}/{device_id}"
        self.mqtt_client.subscribe(f"{topic}/status")
        self.devices[device_id] = Device(device_id, device_type, topic)

    def send_command(self, device_id: str, command: str, value: Any):
        device = self.devices[device_id]
        self.mqtt_client.publish(f"{device.topic}/command", {
            "command": command,
            "value": value,
            "timestamp": time.time()
        })

Features include automated scheduling, energy optimization, and integration with popular smart home ecosystems.
