Upload External Data as a Virtual Device

Creating a Virtual Device

Orange_Line.png

The feature will allow users to upload a data set into the DECK Monitoring system which will appear as a “virtual” device. Data from this virtual device will appear alongside data from all actual devices, and the virtual data will interact with the other components of the system in application features such as analytic graphs and the System Overview page.


This feature can be used for many purposes:

  • to input data for theoretical baselines which the user can compare to actual hardwarereported data
  • to upload historical data into the system
  • to manipulate system data with a formula or a proprietary model and compare against actual hardware-reported data
  • to visualize user-entered data from devices that are not connected to the DECK Monitoring system

When to use the Virtual Device Feature?

This feature has been developed to address speci�c needs that O&M providers and system owners sometimes encounter as they manage system data over the life of a power system:


Historical Data:
Some of our customers operate systems that have generated energy before the DECK monitoring system was installed and properly reporting. If this applies to you, you may want to upload data for power generated before the monitoring system began reporting. This will allow you to see a full historical record of your system in the DECK application.

Downtime Data:
You may also encounter a scenario where data reporting encounters downtime due to an interruption of internet service or some other cause. If this occurs, you may want to manuallyenter data for kWh generated during that period of downtime.

Formula Data:
Some users may wish to take real data from their system and run it through a macro in Excel to illustrate a formula or a proprietary model, then re-upload the manipulated data into the application in order to test the formula against real system numbers.

Projection Data:
Some users may wish to create a spreadsheet of predicted data to use as a projection of system generation. The virtual device feature allows you to upload that data into the application so you can compare the actual numbers to your projections with DECK graphing tools.

Non-metered Data:
Some users may wish to enter data for a variable in the real world that is not metered in the system. For example, this might be a value such as occupancy for an apartment complex, or number of widgets produced for a factory. The virtual device feature allows the user to view that data in application graphs and scatter plots.

How it Works

The link to upload virtual data appears on the System Overview page as seen below:

Clicking on this link will open the Virtual Upload page, where you must complete several fields to name your data set and determine reporting intervals. When all �elds are completed, click on the “Create Device” button at the bottom of the page.

Please note that it is not currently possible to edit virtual data in the DECK application. If you need to correct a data set, you must delete that virtual device in the application, then re-upload the corrected data as a new virtual device.

How to Prepare Your Virtual Data

Virtual data must be prepared in .csv file format for the DECK application
