I am new here to the forum. Today i recieved my EVSE DIN module. I am trying to connect it to a ESP32. But i can not get the RS485 activated. According to the documentation at boot the EVSE DIN should have a solid led for 2-3 seconds in which i have te press a button 5x which shorts AN to GND. But the LED is never solid. The LED starts flashing once every second right away.
Can anyone help me with my problem?
Many thanks in advance.
Do you use BASE-modul too?
Note: ESP32 does not support RS485 out of the box. You need a converter to communicate via RS485! We strongly recommend our base module, instead of an ESP32 Dev Module, as aiole already wrote. It has an integrated RS485 circuit for direct communication with EVSE DIN:
