Esp32 Phnix Heroplus Heat Pump Modbus Register 2014: Temperature vlaue after weather compensation during heating

Technical Definition

The register Temperature vlaue after weather compensation during heating at address 2014 is used to monitor Temperature vlaue after weather compensation during heating on the Esp32 Phnix Heroplus Heat Pump.

• 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 Temperature vlaue after weather compensation during heating (Address: 2014)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=2014, 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: "Temperature vlaue after weather compensation during heating"
  address: 2014
  value_type: S_WORD
  unit_of_measurement: "°C"

💡 Engineer's Insight

Analysis: Temperature adjusted for external weather conditions during heating cycles. Units: Degrees Celsius (°C) or Fahrenheit (°F).

Troubleshooting: Deviations from expected values may indicate faulty outdoor sensors or incorrect weather compensation parameters.
