It is certainly possible. For enhanced security, we have purposely not loaded a bootloader and required a physical connection to update the controller safety firmware.
The controller firmware does not change significantly or often.

I would like to update the OpeEVSE (Atmel AVR) module firmware (not the WiFi ESP module) from the Web interface running on the ESP32 module.
I dont like to take the box apart to do a firmware update - must be done OTA :-)
It seems to be possible using this project:

I guess it requires a bit of additional wiring,
