So I got a little further last night. Turns out the bootloader I was trying to flash was the wrong one, this was the one linked from the GitHub so that may need correcting or I just have completely misunderstood what was written there.
Anyway, once the correct bootloader was flashed and firmware I get a constant flashing LED.

But still firmware :null.
I also cannot change the Node ID or Speed as it appears to be constantly refreshing, so as soon as I select the drop down box it refreshes and deselects.

It's progress but not as much as I'd hoped....

Oh, indeed the wrong boot loader is linked in the README, will correct.

But again, have you flashed the latest https://github.com/jsphuebner/esp32-web-interface to the ESP module?

I have now flashed the CAN Backend version, but it was still not working. unfortunately now I seem to have broken my ESP32 Lilygo TCAN485 board. I performed a "full clean" in PlatformIO in order to reflash and see if the issue would be fixed but since this, I no longer get a wifi network when powering the board. The upload claims to be successful.

Ok I finally got mine BMS boards working yesterday, possibly due to some cheap breadboards/dupont connectors...
I've updated the wiki with the process I used to flash the boards here... https://openinverter.org/wiki/16-cell_B ... g_firmware
Maybe have a read and correct any obvious wrongs if necessary. Thanks for the help!
