.Procon.Base Modbus Register 172: Name last measured total energy produced

Technical Definition

The register name last measured total energy produced at address 172 is used to monitor name last measured total energy produced 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 last_measured_total_energy_produced (Address: 172)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=172, 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 last_measured_total_energy_produced"
  address: 172
  value_type: U_WORD
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Total cumulative energy produced by the device. Units: kWh or MWh.

Troubleshooting: Stuck at zero could indicate no production, sensor failure, or configuration error. Check device operation and sensor wiring.
