Stats Modbus Register 13074: Prefix STAT: Generated Energy Total

Technical Definition

The register prefix STAT: Generated Energy Total at address 13074 is used to monitor prefix stat: generated energy total on the Stats.

• Protocol: Modbus RTU
• Data Type: U DWORD R
• 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 prefix STAT: Generated Energy Total (Address: 13074)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=13074, 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: "prefix STAT: Generated Energy Total"
  address: 13074
  value_type: U_DWORD_R
  unit_of_measurement: "kWh"

Connection Diagram

Here is the standard RS485 wiring for this configuration:

💡 Engineer's Insight

Analysis: Cumulative energy generated since installation (e.g., kWh). Total system energy production.

Troubleshooting: Zero implies no recorded generation or a persistent meter fault. Tracks total system lifetime output.
