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:…".
