## Sigen
_A package to reading and writing data to and from Sigenergy inverters._

### Installation
```bash
pip install sigen
```

### Usage
```python
import logging
import coloredlogs
import os
from sigen import Sigen


def main():
    # Read username and password from environment variables
    username = os.getenv('SIGEN_USERNAME')
    password = os.getenv('SIGEN_PASSWORD')

    if not username or not password:
        logging.error("Environment variables SIGEN_USERNAME and SIGEN_PASSWORD must be set")
        return

    # Initialize logging
    coloredlogs.install(level='INFO')
    sigen = Sigen(username=username, password=password)

    # Fetch and log station info
    logging.info("Fetching station info...")
    station_info = sigen.get_station_info()
    logging.info("Station Info:")
    logging.info(f"Station ID: {station_info['stationId']}")
    logging.info(f"Has PV: {station_info['hasPv']}")
    logging.info(f"Has EV: {station_info['hasEv']}")
    logging.info(f"On Grid: {station_info['onGrid']}")
    logging.info(f"PV Capacity: {station_info['pvCapacity']} kW")
    logging.info(f"Battery Capacity: {station_info['batteryCapacity']} kWh")

    # Fetch and log energy flow info
    logging.info("\nFetching energy flow info...")
    energy_flow = sigen.get_energy_flow()
    logging.info("Energy Flow Info:")
    logging.info(f"PV Day Energy: {energy_flow['pvDayNrg']} kWh")
    logging.info(f"PV Power: {energy_flow['pvPower']} kW")
    logging.info(f"Buy/Sell Power: {energy_flow['buySellPower']} kW")
    logging.info(f"EV Power: {energy_flow['evPower']} kW")

    logging.info(f"Load Power: {energy_flow['loadPower']} kW")
    logging.info(f"Battery Power: {energy_flow['batteryPower']} kW")
    logging.info(f"Battery SOC: {energy_flow['batterySoc']}%")

    # Fetch and log current operational mode
    logging.info("\nFetching current operational mode...")
    current_mode = sigen.get_operational_mode()
    logging.info(f"Current Operational Mode: {current_mode}")

    # Change operational mode (example: setting mode to 'Fully Fed to Grid')
    logging.info("\nSetting operational mode to 'Fully Fed to Grid'...")
    response = sigen.set_operational_mode(5)
    logging.info(f"Response: {response}")

    logging.info("\nFetching current operational mode...")
