Note:

In order to transmit the current measurement value the second measurement values are

averaged over the sampling rate.

The minimum / maximum wind direction indicates the direction at which the minimum /
maximum wind speed was measured.

The wind gust direction is the vector average of the direction measured during the highest 3sec
speed average of the last 10min.
