Sr F000 F060 Sensor Modbus Register 61461: Name LineChgEnergyLast7day1

Technical Definition

The register name LineChgEnergyLast7day1 at address 61461 is used to monitor name linechgenergylast7day1 on the Sr F000 F060 Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: Ah
• 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 LineChgEnergyLast7day1 (Address: 61461)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=61461, 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 LineChgEnergyLast7day1"
  address: 61461
  value_type: U_WORD
  unit_of_measurement: "Ah"

💡 Engineer's Insight

Analysis: Line charge energy over the last 7 days (unit: Wh). Energy drawn from the grid to charge the battery.

Troubleshooting: Zero means no grid charging or a sensor fault. Check grid connection, battery charging status, and Modbus.
