Switchingcabinet Modbus Register 24608: Inepro PRO380 Reverse L2 Active Energy

Technical Definition

The register Inepro PRO380 Reverse L2 Active Energy at address 24608 is used to monitor inepro pro380 reverse l2 active energy 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 Reverse L2 Active Energy (Address: 24608)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=24608, 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: "Inepro PRO380 Reverse L2 Active Energy"
  address: 24608
  value_type: FP32
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Accumulated reverse energy on Phase L2. Units: Kilowatt-hours (kWh).

Troubleshooting: 0 means no reverse flow on L2. Non-zero may indicate export or phase wiring error.
