Device Deye Advanced Modbus Register 268: Name inverter name setting soc timezone1

Technical Definition

The register name inverter name setting soc timezone1 at address 268 is used to monitor name inverter name setting soc timezone1 on the Device Deye Advanced.

• 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 name_inverter_name_setting_soc_timezone1 (Address: 268)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=268, 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_inverter_name_setting_soc_timezone1"
  address: 268
  value_type: U_WORD
  unit_of_measurement: "%"

💡 Engineer's Insight

Analysis: Configured State of Charge (SoC) limit for timezone 1 (%). Sets the target battery charge level for this period.

Troubleshooting: Zero might indicate a configuration error or a disabled setting. Check inverter's time-based SoC configuration.
