Srne Hf2430U60 Modbus Register 61488: Load Power Consumption of the day

Technical Definition

The register Load Power Consumption of the day at address 61488 is used to monitor load power consumption of the day on the Srne Hf2430U60.

• Protocol: Modbus RTU
• Data Type: INT16
• 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 Load Power Consumption of the day (Address: 61488)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=61488, 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: "Load Power Consumption of the day"
  address: 61488
  value_type: INT16
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Total energy consumed by the connected load today, typically in Watt-hours (Wh) or Kilowatt-hours (kWh).

Troubleshooting: 0 Wh/kWh indicates no load consumption. Verify load operation and power supply.
