Hi, I wanna connect my wemos d1 Mini to my Evse wb. I have to connect tx (gpio5) and rx(gpio4) Is gnd also needed ? What’s are the differences between version 1.x.x and version 2.x? Thanks for your help

Yes, you need also to connect GND. It's not very intuitive in the instructions, but it will not work otherwise.

V2 is not open-source and it uses custom hardware. Use google translate https://www.evse-wifi.de/evse-wifi/
