Esphome Deye Modbus Register 192: Device name frecuencia salida

Technical Definition

The register device name frecuencia salida at address 192 is used to monitor device name frecuencia salida on the Esphome Deye.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: hz
• 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 frecuencia salida (Address: 192)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=192, 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 frecuencia salida"
  address: 192
  value_type: U_WORD
  unit_of_measurement: "hz"

💡 Engineer's Insight

Analysis: Output frequency of the inverter. Units: Hz. Reflects stable AC power generation.

Troubleshooting: Zero or incorrect values suggest inverter fault, no grid connection, or configuration issue.
