Lkics2Gw Modbus Register 1408: Friendly name Regulation Output Zone 5

Technical Definition

The register friendly name Regulation Output Zone 5 at address 1408 is used to monitor friendly name regulation output zone 5 on the Lkics2Gw.

• Protocol: Modbus RTU
• Data Type: S WORD
• 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 friendly_name Regulation Output Zone 5 (Address: 1408)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=1408, 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 Regulation Output Zone 5"
  address: 1408
  value_type: S_WORD
  unit_of_measurement: "%"

💡 Engineer's Insight

Analysis: Regulation output for Zone 5. This value likely dictates the heating/cooling intensity for this specific zone.

Troubleshooting: A 0 value may mean the zone is satisfied, inactive, or experiencing a control failure.
