And also i want to migrate to an ESP32 ith Ethernet like the WT32-ETH01 module... do you think it is possible?
Need a votlage regulator i think... but else?

Hi,

Mine is 3243 version. Anyway, it's best to try out yourself the commands.
Sure, u can use ESP32. For the voltage, on the coffee machine u have 5v output

@nighteagle1974 are these your commands for EP3246? I have the same machine but I feed your commands are too short compared to @micki88
For me everything works with @micki88 code except for the powering on the display (which is a big problem for me). The display is not turning on when I send the power on (despite the transistor being correctly wired and successfully disconnecting the display ground for 300ms)

For me it turned out that the display problem had required to also connect pin 3 of the mollex cable (second GND) to the NPN transistor that cuts the power to the display when power on command is sent. Just if anyone has this issue - to know. Cheers
