Wb Mge V3 Modbus Wifi Modbus Register 110: RS485-1 Address 1 Holding 110

Technical Definition

The register RS485-1 Address 1 Holding 110 at address 110 is used to monitor rs485-1 address 1 holding 110 on the Wb Mge V3 Modbus Wifi.

• Protocol: Modbus RTU
• Data Type: INT16
• Unit:
• 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 RS485-1 Address 1 Holding 110 (Address: 110)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=110, 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: "RS485-1 Address 1 Holding 110"
  address: 110
  value_type: INT16
  unit_of_measurement: ""
