So how does WeatherFlow store data?
Explained: your AIR & SKY sensor devices are constantly collecting and sending observations to the HUB. The HUB then uses a set of sophisticated algorithms to inspect the data before publishing to the secure WeatherFlow servers. HUB also makes the data available locally via UDP and BLE broadcast for users who wish to collect and store the data at home.
The secure WeatherFlow servers not only store all the 1min data, but the data is also processed and stored as 5min | 30min | 3hour | 1day . Each temporal resolution is it’s own data set, ready to be queried quickly by the app for your display.
Here’s a more detailed summary of stored data by sensor device and parameter:
