Why does data refresh take longer than in other apps?

Solution

Compared to other apps for the netatmo weather station, myatmo retrieves a huge amount of data from the netatmo data server during startup or data update. This is required to represent the data richness so beloved by the myatmo users and to generate diagrams. The speed depends primarily on the response time of the netatmo data server, as well as the speed of your device's internet connection and the amount of available data.

It is not possible to retrieve this data in the background without simultaneously displaying old as well as current data until all available data has been loaded. Therefore, we have decided to preload the last available data, then to start the data query, to wait until it is completely finished to then present the most recent data in a timely and complete manner.
