Hi

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

https://openevse.dozuki.com/Guide/How+to+Load+OpenEVSE+Firmware+(WinAVR)/7

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

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.

They sold me a board with outdated firmware. After pulling my hair out for several hours, tech support said that I needed a firmware update for the safety module. Then told me to flash the new firmware myself? For $140 I would expect to be purchasing a board that works out of the box. Now I have to wait Weeks? for a new board and then hope that it works. Not happy.

@M Bolyanatz We ship with the latest firmware installed on both the safety controller and WiFi, your board did not have outdated firmware, it had corrupted firmware. You do not "have to wait weeks" a replacement has already been shipped.

How can we help you today?
