Why are there different values in different time spans, but for the same time?


In the myatmo diagrams different values ​​may show up for different times in different time periods. This can be explained as follows:

For larger periods of time, depending on the size of the time period, average values ​​per hour, per 3 hours or similar are retrieved from the netatmo data server because the amount of data is otherwise too large. For smaller periods, myatmo retrieves all available values. This means that average values ​​are displayed for longer periods of time, in each case for the time span as displayed via the x-axis (swipe with your finger, then you can see the respective time span in the tooltip).

In detail:

  • Time periods <4 days: All measured values ​​(thus no calculated average values)
  • Time periods> 4 days <30 days: one value per hour (this is an average of the respective hour)
  • Time periods> 30 days <365 days: one value per day (this is an average of the respective day)
  • Time periods> 365 days: one value per month (that is an average value of the respective month)

So, you'll always see aggregated (average) data depending on the specific data time spans, as generated and calculated by the netatmo data server. This also applies to min - max values of larger time spans. If you need to get more accurate data you must view graphs for single days, only.
