Manual Data Reaggregation

Occasionally it may become necessary to manually "re-aggregate" our data for a given device/system. Some scenarios which might lead to this:

• Readout data is updated without subsequently notifying the aggregation algorithm of this fact
• Some parameters of the site were input incorrectly, such as inverter count etc.
• Previous irradiance data is attached to a site manually (for example a virtual irradiance device)

In such cases the "raw" data retrieved from the devices is correct in the master (MySQL) database, however calculated and aggregated values are not. Such values include:

• Calculated values such as predicted energy, performance ratio, effective availability
• Daily or monthly aggregated values (which appear in reports and on various parts of the site)
• "Site Aggregator" system data, in other words, data stored for "Virtual Master Meter" type devices

To manually trigger a full "reaggregation" of all data for a system, log into the website as Demo or Zoltan, open the site details page for the given energy site and go to Readings → Diagnostics. 

Select the system to re-aggregate and then use the appropriate button to initiate the data re-aggregation:

The process may take several minutes to complete. Once done, you should see "success: true":

The pop-up does not need to be open for the process to complete.

If there are many systems/subsystems, then don't wait for a result in the pop-up. Instead, close it and open the aggregation status page: 

You can then see all of the devices marked for complete reaggregation:

You will know that the reaggregation has completed once the list empties and instead you see the reloaded devices under "Completely reaggregated:…".
