Set up a Solar-Log data logger

📗

General tips

Have the data source (data logger, etc.) serial number on hand. When entering the serial number, pay attention to uppercase and lowercase letters and empty spaces.
The data source name can be freely selected. For recommendations, see our Naming guideline.
Set the same aggregation interval for all data sources in the system to ensure charts are accurately displayed in VCOM. This is used to normalize uneven timestamps and aggregate smaller recorded intervals into larger ones.
To ensure that the data source aggregation interval has been set correctly in VCOM, open an imported file in the Data logger overview portlet in VCOM and check the timestamps.
We strongly recommend ticking the check box Automatic device creation to ensure that VCOM automatically creates any new devices found during each data import.
If possible, perform a connection test once you have completed the configuration in both VCOM and the data source.

Data loggers only

For data loggers, update the firmware to the latest version prior to configuration.
For data loggers, any import that uses FTP can also use SFTP. The access data, such as the FTP server address, user name, and password remain identical. Only the port changes from port 21 (FTP) to port 2222 (SFTP).

APIs only

If you experience import issues with the API, please contact the respective API provider first.
Each day at midnight, VCOM checks for complete data and requests data from the past 7 days. If there are no limitations from the API and the data is available, the gaps will be filled.
