Switchingcabinet Modbus Register 24580: Inepro PRO380 Total Active Energy Tariff 2

Technical Definition

The register Inepro PRO380 Total Active Energy Tariff 2 at address 24580 is used to monitor inepro pro380 total active energy tariff 2 on the Switchingcabinet.

• Protocol: Modbus RTU
• Data Type: FP32
• Unit: kWh
• Access: Read Only

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 Inepro PRO380 Total Active Energy Tariff 2 (Address: 24580)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=24580, count=2, unit=1)

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

client.close()

Integration (Home Assistant)
