ESP32 IDF IEC61851/SAE J1772 EVSE
Source code intended for a Prototype IEC61851/J1772 EVSE Interface:
https://www.beyondlogic.org/prototype-iec61851-j1772-evse-interface/
The above interface is already working with a dsPIC33EP:
https://github.com/craigpeacock/dsPIC33EP_IEC61851_J1772_ChargePort_EVSE/tree/main/EVSE.X
The hope is to port it to the ESP32 and use WiFi/MQTT (on a single chip) to obtain electricity pricing information or solar PV instantaneous generation data.
