Kincony M30 Custom Modbus Register 333: m30 L3 Temp 01

Technical Definition

The register m30 L3 Temp 01 at address 333 is used to monitor m30 l3 temp 01 on the Kincony M30 Custom.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: °C
• 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 m30_L3_Temp_01 (Address: 333)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=333, 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: "m30_L3_Temp_01"
  address: 333
  value_type: U_WORD
  unit_of_measurement: "°C"
