Data Storage
The amount of historical measurement data stored is directly tied to the measurement interval set on the device:
1
6
2
12
5
30
10
60
Memory management
Altering the measurement interval triggers a restructuring of existing data in the memory system.
For instance, switching from a shorter interval (e.g., 1 minute) to a longer one (e.g., 10 minutes) aggregates ten 1-minute measurements to compute and store an average value. Conversely, adjusting from a longer interval (e.g., 10 minutes) to a shorter one (e.g., 1 minute) generates supplementary data in 1-minute intervals by extrapolating values from 10-minute measurements, creating a sequence of 10-minute "steps" with identical values.
Frequent changes in measurement intervals are discouraged due to the resulting data loss caused by averaging and padding.
If more frequent measurements are required, use the "on-demand measurement" feature for instant measurement.
Background data download
The data can be downloaded in the background if the application runs as a background process and "Background data read" is enabled in the app settings.
