How to Read (Python pymodbus)

Use this code snippet to read this specific value via RS485:

from pymodbus.client.sync import ModbusSerialClient

client = ModbusSerialClient(method='rtu', port='/dev/ttyUSB0', baudrate=9600)
client.connect()

# Read inverter_name Unknown4519 (Address: 4519)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=4519, count=2, unit=1)

if not result.isError():
    print(f"Raw Value: {result.registers}")
else:
    print("Error reading register")

client.close()

Integration (Home Assistant)

Paste this into your configuration.yaml:

- platform: modbus_controller
  name: "inverter_name Unknown4519"
  address: 4519
  value_type: U_WORD
