Hi, I got 2 questions regarding the webserver:
- Do you have any tutorial on how to plot a line graph in a webserver?
- Can we access the data in SD card through the webserver? if can, do you have tutorial on it?
Hello Nazmie, that’s a great project idea, but unfortunately I don’t have anything like that at the moment.
- Yes, it’s possible to use and create graphs with a standalone ESP web server, but since it’s not practical most people send the values to a cloud service or home automation platform (Home Assistant, Node-RED, etc)
- Yes, but I don’t have any tutorials on that exact subject. You would need to open the SD card file that has the values and print them in the web server page…
