Deye Inverter Entities Sensor Modbus Register 292: Name inverter name generator peak shaving power

Technical Definition

The register name inverter name generator peak shaving power at address 292 is used to monitor name inverter name generator 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 generator peak shaving power (Address: 292)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=292, 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 generator peak shaving power"
  address: 292
  value_type: U_WORD
  unit_of_measurement: "W"

💡 Engineer's Insight

Analysis: Peak power (Watts) the generator can supply for shaving grid demand during high-cost periods.

Troubleshooting: Zero indicates the generator is not active or available for peak shaving. Check generator status and inverter configuration.
