Esphome Deye Modbus Register 96: Device name produccion total

Technical Definition

The register device name produccion total at address 96 is used to monitor device name produccion total on the Esphome Deye.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: KWh
• 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 device_name produccion total (Address: 96)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=96, 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: "device_name produccion total"
  address: 96
  value_type: U_WORD
  unit_of_measurement: "KWh"

💡 Engineer's Insight

Analysis: Total cumulative energy production. Units: kWh. Overall system output since installation.

Troubleshooting: Static value suggests production is halted. Review daily production, inverter status, and error logs.
