The actual firmware for the wifi module is 2.5.0 and after chenging the SSID name and pasword can not connect to the network.
I'm using linux and there's no guide on how to flash the firmware using this S.O.
I tried, installed avrdude and followed the redme from github. I ended up with this error:
sudo avrdude -p atmega328p -B6 -c usbasp -P usb -e -U flash:w:open_evse.hex avrdude: set SCK frequency to 93750 Hz avrdude: error: program enable: target doesn't answer. 1 avrdude: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check.
I'm in Europe, and flashing the precompiled release 7.1.3... hope it's ok... and hoping ot will solve the wifi problem to...
Updating the OpenEVSE controller firmware will not likely fix your WiFi issue.
WiFi version 2.5.0 is the older ESP8266 module, the highest WiFi version supported is 2.9.1 here:
This update can be flashed over the air using the WiFi interface.
This version of WiFi recommends 4.8.0+ on the controller, 5.0.1 would likely be optimal.
