I would like to plot data in real time from a temperature sensor (BME280 + ESP32) using Blynk. However, I need the chart to update and receive data every second at the time frame at least 15 minutes, is it possible using Blynk ?
I know there is an option to use a live chart, I just think it is limited to a certain amount of points.
Have you tried testing this?

No, I watched a few youtube videos with this wiring. I saw that on the live graph the data is updated every second, I want to know if this also applies to a 15-minute time frame. For my project is very important to send data every second or two and have the same chart refresh rate.
No, data is written to the the 15 minute timeframe once every minute.
However, the live data timeframe does allow you to scroll backwards and see data from 15 minutes ago.

Does this work on the mobile app as well ?
Also, can I have live chart and 15 minute time frame chart active at the same time to receive data from the same sensor on mobile ?
Why don’t you do some simple tests to see if Blynk meets your needs?
