Not working after HA Core Update 2025/1

Since HA Core Update 2025/1 the integration doesn't anymore:

_Logger: homeassistant.setup

Unable to prepare setup for platform 'remko_heatpump.sensor': Platform not found (cannot import name 'TEMP_CELSIUS' from 'homeassistant.const' (/usr/src/homeassistant/homeassistant/const.py))._

Found a solution. In sensor.py you must change

from homeassistant.const import TEMP_CELSIUS, POWER_KILO_WATT, POWER_WATT
to
from homeassistant.const import UnitOfTemperature, UnitOfPower

and of course also the value of the unit return for each sensor

[Dragancokan]

What exactly do you mean by: and of course also the value of the unit return for each sensor?

For sensors with unit temperature:
from:

@ property
    def unit_of_measurement(self) -> str:
        """Return the unit of measurement."""
        return TEMP_CELSIUS

to:

@ property
    def unit_of_measurement(self) -> str:
        """Return the unit of measurement."""
        return UnitOfTemperature.CELSIUS

For sensors with unit power
from:

@ property
    def unit_of_measurement(self) -> str:
        """Return the unit of measurement."""
        return POWER_WATT

to:

@ property
    def unit_of_measurement(self) -> str:
        """Return the unit of measurement."""
        return UnitOfPower.WATT
