.Procon.Base Modbus Register 227: Name consumed electric power

Technical Definition

The register name consumed electric power at address 227 is used to monitor name consumed electric power on the .Procon.Base.

• Protocol: Modbus RTU
• Data Type: U WORD
• 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 name consumed_electric_power (Address: 227)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=227, 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 consumed_electric_power"
  address: 227
  value_type: U_WORD
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Power drawn by the device from the grid or source. Units: kW or MW.

Troubleshooting: Unexpected zero may indicate standby mode, device off, or power supply issue. Check power source and device status.
