Technical Definition

The register Battery Percentagename suffix at address 229 is used to monitor battery percentagename suffix on the Single Pow Hvm62K 48V Lip.

  • Protocol: Modbus RTU
  • Data Type: U WORD
  • Unit: %
  • 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 Battery Percentagename_suffix (Address: 229)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=229, 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: "Battery Percentagename_suffix"
  address: 229
  value_type: U_WORD
  unit_of_measurement: "%"

💡 Engineer's Insight

Analysis: State of Charge (SoC) of the battery, expressed as a percentage (%). Indicates available capacity.

Troubleshooting: 0% means battery is fully discharged. May indicate charging fault or battery issue.
