Hi Dualin2,

Yes! That is possible, i already did it. But it is a lot of coding needed and you need to use the second processor of the esp32. Additionally a voltage step-up from 3.3 to 5V to power the Nextion via esp32. The max sitze you can use is the 3.5 because of the current limit of the esp32 pins.

But yes, as i said, IT IS possible and in simhub you need to define a lot of serial Data points. It is still working over BL-classic, but i also did a Version using esp-now (WiFi), so that is also possible

At the moment im using all of this in a custom wheel powered by the wheelbase itself (3.3V)
