# Abstraction Layer

The abstraction layer is an asyncio-based worker that manages device communication through MQTT.

## Features

- **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

## Running

```bash
# Start the abstraction worker
poetry run python -m apps.abstraction.main
```

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

## Configuration

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

```yaml
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

Press `Ctrl+C` to gracefully stop the worker.
