python-dcm230

python-dcm230 provides a simple, Pythonic interface for reading and writing data from Eastron DCM230 DC meters over Modbus RTU. It builds on top of pymodbus.

Example usage:

from dcm230 import Dcm230
from pymodbus.client import ModbusSerialClient

# Configure the Modbus client
client = ModbusSerialClient(
   port="COM3",  # or "/dev/ttyUSB0" on Linux
   baudrate=9600,
   parity="E",
   stopbits=1,
   bytesize=8,
   timeout=1,
)

# Device Modbus address
device_address = 1

# Initialize the Dcm230 driver
meter = Dcm230(device_address=device_address, client=client)

# Read voltage
voltage = meter.V
print(f"Voltage: {voltage} V")
