Technical Definition

The register Inepro PRO380 Reverse L1 Active Energy at address 24606 is used to monitor inepro pro380 reverse l1 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 L1 Active Energy (Address: 24606)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=24606, 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 L1 Active Energy"
  address: 24606
  value_type: FP32
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Accumulated reverse energy on Phase L1. Units: Kilowatt-hours (kWh).

Troubleshooting: 0 means no reverse flow on L1. Non-zero may indicate export or phase wiring error.
