Convert a temperature value from Celsius to the device-preferred scale.

@param float  $temperature_in_celsius The temperature to convert.
@param string $serial_number          The thermostat serial number. Defaults to the first device of the account.

@return float Temperature in device-preferred scale.
Convert a temperature value from Celsius to the device - preferred scale .
