There is current system data available in Sunny Portal, but our customer continually receives empty reports via e-mail.
The time entered for when the report is to be created is too early.
Either the data logger (e.g. Sunny WebBox) has not yet sent the data to the Sunny Portal, or the Sunny Portal has not yet processed it.
Corrective measure:
Please set the time at which the report is to be sent to a later time in Sunny Portal via “Configuration > Report configuration”.
Information:
An overview of the different reports and their creation can be found in article Sunny Portal: Overview, Creating and Configuring of Reports.
