Factory Reset #75

Closed Schnitzn closed 1 year ago

Schnitzn commented 1 year ago

Unfortunately my EVSE does not recognise my EV anymore when connecting. I already checked and temporarily switched cable and car but these seem to be OK communication-wise. Firmware + Spiffs re-upload also did not fix it.

How can I make factory reset to the EVSE to start from scratch?

For a factory reset, just reflash the original firmware and spiffs.

To diagnose, recompile the serkri distribution after modifying include/evse.h : comment

define DEBUG_DISABLED 1, and modify

define LOG_EVSE LOG_INFO to

define LOG_EVSE LOG_DEBUG;

After reflashing you can telnet to your SmartEVSE, and it will tell you what value is measured at the PP pin; that determines the value of "CONNECTED".

Post your PP pin value here when your car is connected....

Thanks. When reflashing original firmware, my settings still remain stored (WIFI, current limit...). Any way to make a full wipe?

With esptool, flash all zeroes to the esp32, then reflash firmware and spiffs. This will zero out the NVS settings.

Thanks. "http://EVSE IP-address/erasesettings" also worked out even EV connection issue was finally not related to this. Thanks to Michael Stegen
