Deye Inverter Entities Sensor Modbus Register 76: Name inverter name grid energy imported today

Technical Definition

The register name inverter name grid energy imported today at address 76 is used to monitor name inverter name grid energy imported today on the Deye Inverter Entities Sensor.

• 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 name inverter_name grid energy imported today (Address: 76)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=76, 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 grid energy imported today"
  address: 76
  value_type: U_WORD
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Energy imported from the grid today (kWh). Measures total power consumed from the utility supply.

Troubleshooting: Zero value implies no grid import today, possibly due to self-sufficiency or grid outage. Check consumption and grid status.
