Just THANK YOU!

I have bought the small (100x100mm) hot plate heater, removed the original controller (it was only capable to set the desired temperature and it kept it there) and used your code with ESP32 to do the job - almost no changes - only LCD out as I tested it without any screen.
My first impression is: AMAZING!
I will also put ILI9341 display with some more buttons or so (or rotary encoder) or even the touch version of ILIILI9341 - the graphic library will take some time but ok.

But what I am most amazed with: your PID settings did the job almost without tweaking. My first PCB done and dusted.

So: THANK YOU again!
