Good questions @caredlands … will explain further. SKY samples wind every 3sec. and displays those instant values in the 360deg circular dial on the blue dashboard view (or every 15sec if you choose to toggle your SKY to ‘power save’ mode for 2yrs+ battery life). The HUB stores the 3sec values, then calculates and publishes the 1min avg to WeatherFlow servers for data archive. There are also some pretty sophisticated algorithms on the HUB that inspect the data from the SKY before sending to be archived. (Note: the HUB also makes the 3sec data available via local UDP broadcast for users who wish to collect and store.) The 1min data is displayed immediately right of the wind dial on the blue dashboard view of the apps.
The WeatherFlow servers archive all data in temporal bins for future query (by the apps, website, etc). The data archive bins are as follows: 1min data points, 5min data, 30min data, 3hr data, 1day data. You will notice that each + / - tap on the graph will change the temporal resolution of the graphed data according to the data archive bins. Click the minus all the way brings you to the 1day data display. For wind, the 1day data graph shows the average wind speed over the course of that day, the highest gust, the lowest lull, and the direction vector avg. The temporal toggle allows the user to inspect a broad range of data at the resolution / granularity desired.
The wind graph above has been zoomed out to 1day data (one data point for each day). Tapped on May 20th as example. The summary for May 20 at the top shows: “1.6 (0.0 - 16.6) mph W” which translates to the wind during May 20th averaged 1.6mph with a low lull of 0.0mph and a high gust of 16.6mph and an average directional vector of West.
