For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the
change in weather. If the icons do not change, then it means either the air pressure has not changed or the change
has been too slow for the Weather station to register. However, if the icon displayed is a sun or raining cloud, there
will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons
are already at their extremes.
The icons display weather forecasts in terms of getting better or worse, and not necessarily sunny or rainy as each
icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that
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 rainy.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 48 hours. This will allow sufficient
time for the Weather Station to collect air pressure data at a constant altitude and therefore result in a more accurate
forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is
estimated to have an accuracy level of about 75% due to the varying areas the Weather Station has been designed
for use in. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather
Station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example
mostly sunny).
