Deye Inverter Entities Sensor Modbus Register 293: Name inverter name grid peak shaving power

Technical Definition

The register name inverter name grid peak shaving power at address 293 is used to monitor name inverter name grid peak shaving power on the Deye Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: W
• 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 peak shaving power (Address: 293)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=293, 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 peak shaving power"
  address: 293
  value_type: U_WORD
  unit_of_measurement: "W"

💡 Engineer's Insight

Analysis: Indicates the power consumed from the grid for peak shaving by the inverter. Units are typically Watts (W).

Troubleshooting: Zero value might mean peak shaving is disabled or not currently active. High values could indicate high demand or specific operational modes.
