Deye Inverter Entities Sensor Modbus Register 37: Name inverter name modbus address

Technical Definition

The register name inverter name modbus address at address 37 is used to monitor name inverter name modbus address on the Deye Inverter Entities Sensor.

• 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 modbus address (Address: 37)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=37, 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 modbus address"
  address: 37
  value_type: U_WORD
  unit_of_measurement: ""

💡 Engineer's Insight

Analysis: Address of the specific inverter sensor within the Modbus map. Identifies data location.

Troubleshooting: Zero value is invalid for an address. Indicates configuration error or communication issue.
