Hi, Nice video. I think these types of projects would be easier for someone with a web development background. As I come as a long time Arduino hobbyist and more recent Python/microPython hobbyist I struggle to understand the html, css, and javascript. I am impressed that you are fluent in at least 4 code languages. Maybe one day I will get there.

Thank you very much for your thorough explanation and tutorial. I have decided for my robotics use case that I am going to experiment with MQTT instead. It seems like WebSockets may be more complicated than necessary for my communication system.

All your tutorials are excellent !
Nothing could be missed and skipped...

Hey, let me know if something is not clear with this project. I am quite surprised myself how responsive MicroPython is in handling the insane amount of sensor readings and how Plotly.js is still able to display the chart. Both these two combination is really awesome.

DonskyTech

Compelling, and challenging. I do struggle keeping nodejs/js and python straight...maybe chatgpt will rescue me. Now consider adding some rotary encoders and interrupts to the mix, and please continue the great work.

Very interesting, is there a minimal example how to update a single value on the html page? Lets say a temp value read by a dht sensor.
