would you recommend a simple and compact graphic libraty to generate charts on a web page based on sensors readings
Hello Fred, for which board and using which programming language?
Do you want to create a web server on an ESP32 that plots graphs?
I am using TTGO LoRa32 OLED boards developping programs with Arduino 1.8.7 IDE
I would like to monitor board activities in particular
Temperature via OW bus
GPIO Analog inpouts
GPIO Didital In and Out puts
via simple graphs vs time
In my option, it’s a bit tricky to setup a real-time web server for data using an ESP32… I prefer to use my ESP32 to send data to a home automation platform and plot the values there… (in Node-RED, Home Assistant, etc)
Thanks for your answer
I will keep investigating the matter since setting up a full home automation platform just to plot few data is a bit of an overkill
I will let you know
You might also consider sending that data to an online service like thingspeak.com . With thingspeak you can plot your data and access it from anywhere. That might be a better alternative
