Calculation of average wind speed is inaccurate, or display of average is selecting wrong variable & displaying Max as Avg

Hello radowningii,
What is the display reading and what do you believe it should be reading? This display shows peak and average wind readings. The peak wind is the highest speed form the last 60 minutes.  The average reading is the average wind speed over the past 2 minutes.  Thank you.

Just revisiting this. The answer is that average wind speed is: 1) not being calculated accurately no matter how you look @ it, and; 2) the wind speed average is not displaying whatsoever. Pick any 24-hour period, look @ what is calculated by your app, then take the raw data & calculate it yourself. Obvious miscalculation.

Hello Radowningii,

Please provide us with an example of what you are referring to? What do you think you should have for the readings, and what is it displaying?

I've figured it out: the 'average' is being calculated as a 'moving average" over a period of two or three measurements greater than zero, with zero values being ignored. Attached pic shows wind-speed [green], your reported avg [orange], actual moving average over six periods [red]

I'm having this same problem.  We had a major storm on June 1-2 with wind speeds of 90+ mph.  My max wind speed for the period from June 1, 2018 through June 17, 2018 shows as 14 mph and the average as 46 mph.  How do you have an average wind speed higher than the max?
