Backup data after Blynk servers go offline in December

After 5 years my Blynk wireless weather station will sadly stop working when Blynk pull the plug on its legacy servers. How do I backup my historic data so I can transfer it to my personal server?

Thanks

Blynk Legacy only allows a limited number of data points to be exported, which will only give you a very limited history - depending on the resolution of the data.

The daily average for the past 6 months is about as far back as you can go, and, there’s no facility to import this data into your local server - you’d need to figure that part out for yourself.

You may want to change your code to use a free database server. Download the Blynk csv data and upload it to a DB table.
