• The weather forecast covers a range of 12 hours and indicates only a general weather trend. For
example, if the current weather is cloudy and the rain symbol is displayed, it does not mean the
product is faulty because it is not raining. It simply means that the air pressure has dropped
and the weather is expected to get worse but not necessarily rain. The accuracy is about 70 %.
• The sun symbol also appears on a starry night.
Note:
• Please note that the forecast symbol will become more defined in the course of operation. The
forecast symbol is active right from the start, however, the reliability of the forecasts increases
with the amount of data collected.
