With the software NodeMCU-PyFlasher and NodeMCU-PyFlasher the openevse_huzzah32.bin is installed
flash and done?
1) AFAIK, you cannot update the Controller firmware using NodeMCU; AVRISP and avrdude are the only way to update the Controller firmware.
2) The ESP's firmware can be updated via NodeMCU *if* you have a ESP32 module that has a USB interface. For other versions of the ESP32, a separate USB<->TTL hardware adapter is required for firmware updating, and esptool software.
If the above is incorrect -- if you know a way to update the Controller firmware without AVRISP & avrdude -- please post here so we can all benefit.

Hi friend. the .bin files in which folder it has to be to flash.
Just received my openevse 5.5 board
However, upon checking some of the options it seems some are missing
My version is 7.1.3, but the latest is 8.2.0.
I bit dissapointed that I did not received a module with the last release
Looking at the upgrade instructions, and they don't seem to have been updated
On one of the last steps, it mention yo need 3 files; flash.bat, open_evse.hex and eeprom_24.bin
However, on the repository for the last release ( 8.2.0) there are a couple of hex files ( I assume I should use openevse.hex), there is no bin o flash.bat files
What am I missing?
should just run the command to flash the hex file as per the Readme file:
`$ avrdude -p atmega328p -B6 -c usbasp -P usb -e -U flash:w:firmware.hex`
Any help appreciated
