Technical Definition

The register friendly name Setting Power Timezone6 at address 261 is used to monitor friendly name setting power timezone6 on the Esp%20Inverter.

  • 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 friendly_name Setting Power Timezone6 (Address: 261)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=261, 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: "friendly_name Setting Power Timezone6"
  address: 261
  value_type: U_WORD
  unit_of_measurement: "W"
