Lkics2Gw Modbus Register 1306: Friendly name Set Temperature Zone 4

Technical Definition

The register friendly name Set Temperature Zone 4 at address 1306 is used to monitor friendly name set Temperature zone 4 on the Lkics2Gw.

• Protocol: Modbus RTU
• Data Type: S 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 friendly_name Set Temperature Zone 4 (Address: 1306)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=1306, 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 Set Temperature Zone 4"
  address: 1306
  value_type: S_WORD
  unit_of_measurement: "°C"

💡 Engineer's Insight

Analysis: Sets the target Temperature for Zone 4. Units are typically degrees Celsius (°C) or Fahrenheit (°F).

Troubleshooting: Zero indicates an uninitialized state, communication error, or a disabled zone. Verify configuration and device status.
