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 name PVEnergyLast7day2 (Address: 61441)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=61441, 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: "name PVEnergyLast7day2"
  address: 61441
  value_type: U_WORD
  unit_of_measurement: "kWh"
