Asset data
Data view
The Data view in Eliona offers a detailed overview of the raw data written into a asset written raw data. This includes, among other things, measurements, events or aggregated data from sensors or devices. Unlike in graphical representations (e.g. lines or charts), the Data view displays the values in tabular form, so that the numbers are directly visible.
The Data view is especially useful for:
Monitoring the status of a Assets using concrete measured values in real time.
Individual tracking data points precisely and checking them.
providing data foundations for reports and detailed analyses.
The chronological sorting of the data makes it easier to recognize time-based patterns and identify irregularities more quickly.

Show aggregated data
In Eliona, measured values can be displayed not only as raw data, but also in aggregated form displayed. Aggregations make it possible to present large amounts of data clearly and in different time intervals .
Enable aggregated data
Click on [L], to display the aggregated data . ▷ The view switches from raw data to aggregation view.
Set period: In [L1] you can define for which period the data should be aggregated.
Select aggregation interval: Select in [L2] which time steps the data should be aggregated in (e.g. hourly, daily, weekly).
Select attribute: In [L3] you can determine which attribute should be aggregated.
Set aggregation mode: In [L4] there are various aggregation modes available:
Average
Sum counter
Cumulative counter
Minimum
Maximum
▷ more about this can be found -> here.
Apply settings: Click on [L5], to apply the changes made.
Reset settings: If necessary, you can reset the filters with [L6] .
Show aggregated data: The calculated values appear in [L7] in a tabular view.
Aggregated data enable a better overview of long-term developments and help to analyze data flows efficiently.

Use of Timescale for storing time-based data
The use of TimescaleDB in Eliona enables efficient storage and management of time-based data, especially for changing values. By storing only values that have actually changed, storage space is optimized without compromising the integrity of the data.
Example: Changes over time
Let us look at the data recorded at regular intervals:
Original data without Timescale
Each time record contains all values, even if they have not changed:
Data structure with Timescale
With TimescaleDB we only store the values that have actually changed. This reduces redundant data and improves performance:
