    Climate entity now validates temperature provided in action calls

    G Johansson1 min read

    Core and integrations

    As of Home Assistant Core 2024.8, we have implemented validation for the temperature action call provided by the ClimateEntity.

    Integrations no longer need to check this within their own set temperature methods (async_set_temperature/set_temperature).

    However, it's important that integrations specify the min_temp and max_temp properties correctly, or the user might not be able to set their correct temperature if validation fails. Likewise, integrations that handle devices which can operate on both Celsius and Fahrenheit need to convert their respective min_temp and max_temp values accordingly.

    Example

    Converts a device's native min/max value into the temperature_unit specified by the integration.

    Python
    
class MyClimateEntity(ClimateEntity):
    """Implementation of my climate entity."""

    @property
    def min_temp(self) -> float:
        """Return the minimum temperature."""
        return TemperatureConverter.convert(
                self.device.min_temp, UnitOfTemperature.CELSIUS, self.temperature_unit
            )

    @property
    def max_temp(self) -> float:
        """Return the maximum temperature."""
        return TemperatureConverter.convert(
                self.device.max_temp, UnitOfTemperature.CELSIUS, self.temperature_unit
            )
