Device Deye Advanced Modbus Register 272: Name inverter name setting soc timezone5

Technical Definition

The register name inverter name setting soc timezone5 at address 272 is used to monitor name inverter name setting soc timezone5 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_timezone5 (Address: 272)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=272, 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_timezone5"
  address: 272
  value_type: U_WORD
  unit_of_measurement: "%"

💡 Engineer's Insight

Analysis: Deye inverter setting for State of Charge (SoC) related to Timezone 5. Units are typically percentage.

Troubleshooting: Zero value may indicate misconfiguration, disabled feature, or communication error with the inverter's internal clock/scheduling.
