Device Jkpb0116 Modbus Register 4796: Name bms name total runtime in seconds

Technical Definition

The register name bms name total runtime in seconds at address 4796 is used to monitor name bms name total runtime in seconds on the Device Jkpb0116.

• Protocol: Modbus RTU
• Data Type: U DWORD
• Unit: s
• 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_bms_name_total_runtime_in_seconds (Address: 4796)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=4796, 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_bms_name_total_runtime_in_seconds"
  address: 4796
  value_type: U_DWORD
  unit_of_measurement: "s"

💡 Engineer's Insight

Analysis: Total runtime (seconds). Cumulative time the battery has been in operation. Useful for tracking usage and estimating lifespan.

Troubleshooting: Zero runtime indicates the device or battery has not been used. Large, unexpected values might suggest a timer reset or fault.
