Exporting Data from Blynk to CSV
Exporting via Web Dashboard
To export data from Blynk to a CSV file, users must utilize the web dashboard feature available in Blynk 2.0. It is important to note that a paid plan is required to perform this operation. For accurate data retrieval, the data aggregation option should be set to raw data. Once configured, the "Download Report" option may be used to initiate the export process.
Preparing Data for Export with Superchart
Blynk's Superchart widget, which can collect data from devices such as a CO2 sensor, provides the capability to export historical data to Excel. When exporting data that has been sent to the Blynk server more frequently than once per minute per pin, the Superchart widget will average this data in the resulting CSV file. Additionally, CSV files are generated in compressed .gz format, which must be unzipped prior to opening in Excel.
Configuring CSV Data Records
When setting up the CSV file configuration, users can opt to record the maximum values for a pin as well as the timestamp when the maximum value occurred. This functionality is available for both local and cloud Blynk servers and can be selected before the data export process begins. However, it is important to remember that the mobile app does not support the report widget; therefore, users should choose the "save raw data" option for each datastream when exporting.
