Configuration Loading: Reads device configuration from config/devices.yaml
MQTT Integration: Connects to MQTT broker for real-time device communication
Async Design: Built with asyncio for efficient concurrent operations
Message Subscription: Listens to home/# topics for device events
Logging: Structured logging at INFO level

Environment Variables

Variable	Default	Description
`MQTT_BROKER`	`172.16.2.16`	MQTT broker hostname/IP
`MQTT_PORT`	`1883`	MQTT broker port

What the Worker Does

The worker will:

Load configuration from config/devices.yaml
Connect to MQTT broker (172.16.2.16:1883)
Subscribe to topic home/#
Log "Abstraction worker started" at INFO level
Keep running and processing MQTT messages until interrupted

Configuration

The worker reads configuration from config/devices.yaml. Example structure:

mqtt:
  broker: "172.16.2.16"
  port: 1883
  client_id: "home-automation-abstraction"
  keepalive: 60

devices:
  - id: "light_living_room"
    type: "light"
    name: "Living Room Light"
    mqtt_topic: "home/living_room/light"

MQTT Broker

The worker connects to a real MQTT broker at:

Host: 172.16.2.16
Port: 1883
Authentication: None required

Topics subscribed:

home/# - All home automation topics

Dependencies

PyYAML: Configuration file parsing
aiomqtt: Modern async MQTT client
asyncio: Asynchronous I/O

Stopping
