Asset Data
Data View
The Data View in Eliona offers a detailed overview of the raw data written to an asset. This includes, among other things, measured values, events, or aggregated data from sensors or devices. Unlike in graphical representations (e.g., lines or graphs), the Data View displays the values in a tabular form, so that the numbers are directly visible.
The Data View is particularly useful for:
Monitoring the status of an asset with concrete measured values in real time.
Tracking and checking individual data points precisely.
Providing data for reports and detailed analyses.
The chronological sorting of the data makes it easier to recognize time-based patterns and to identify irregularities more quickly.
[B]
Filter
Here you can select which data from which asset types you want to see.
[C]
Sorting
Here you can select whether the sub-assets should be displayed in geological or functional sorting.
[D]

Display Aggregated Data
In Eliona, measured values can be displayed not only as raw data but also in an aggregated form. Aggregations make it possible to display large amounts of data in a clear manner and in different time intervals.
Activate Aggregated Data
Click on [L] to display the aggregated data.
▷ The view switches from raw data to the aggregation view.
Set time period: In [L1], you can define the period for which the data should be aggregated.
Select aggregation interval: In [L2], select the time steps in which the data should be aggregated (e.g., hourly, daily, weekly).
Select attribute: In [L3], you can determine which attribute should be aggregated.
Set aggregation mode: In [L4], various aggregation modes are available:
Average
Sum Counter
Cumulative Counter
Minimum
Maximum
▷ You can find out more about this -> here.
Apply settings: Click on [L5] to apply the changes.
Reset settings: If necessary, you can reset the filters with [L6].
Display aggregated data: The calculated values appear in [L7] in a tabular view.
Aggregated data allows for a better overview of long-term developments and helps to analyze data flows efficiently.
Add New Data Entry
Add new entry Click on Add new entry [P].
▷ The "Add new data entry" window opens.
Select attribute Select the desired attribute from [S].
Enter value Enter the desired value in the corresponding field [T].
Confirm entry Click on Add new entry again to confirm the entry.
▷ The entry for the attribute is written to the heap with the current timestamp.
Edit Individual Historical Data
Display pencil icon Move the mouse over the desired data entry.
▷ A pencil icon appears next to the entry.
Edit data entry Click on the pencil icon [R] to edit the data entry.
▷ The "Edit asset data entry" window opens.
Enter new value Enter the new value for the entry.
Save changes Click on Save to apply the changes.
▷ The new value replaces the old value in the data set.
Pay attention to which data you are overwriting. Changes to existing data sets can be irreversible and permanently replace important information.
Bulk Editing of Data
If you want to change data in large quantities, for example, because a device supplied incorrect data on a certain day, you can easily do so. With the bulk editing function, all data within a defined time period can be set to a desired value.
Open bulk editing window Click on [Q] to open the Bulk Editing of Data window.
Set time period Enter the from and to date as well as the times to set the period in which the data should be changed.
Select attribute Select the attribute whose data you want to change.
Set value Enter the new value that should replace the existing data.
Save change Click on Save to apply the changes.
▷ All data of the selected attribute in the specified period is set to the new value.
Using Timescale for Storing Time-based Data
The use of TimescaleDB in Eliona enables efficient storage and management of time-based data, especially with changing values. By storing only actually changed values, storage space is optimized without affecting the integrity of the data.
Example: Changes over time
Let's look at the data that is recorded at regular time intervals:
Original data without Timescale
Every time record contains all values, even if they have not changed:
ts: 2024-07-24T16:20: {cop: 36, jaz: 56, power: 18.83, energy: 461.51}
ts: 2024-07-24T16:21: {cop: 50, jaz: 56, power: 18.83, energy: 461.51}
ts: 2024-07-24T16:22: {cop: 100, jaz: 56, power: 18.83, energy: 461.51}Data structure with Timescale
With TimescaleDB, we only store the values that have actually changed. This reduces redundant data and improves performance:
ts: 2024-07-24T16:20: {cop: 36, jaz: 56, power: 18.83, energy: 461.51}
ts: 2024-07-24T16:21: {cop: 50}
ts: 2024-07-24T16:22: {cop: 100}Last updated
