Upgrading Firmware Errors OpenEVSE 4.1.0 Hardwired Ethernet

I hope this is the right place to ask this.

I have a (non DIY) OpenEVSE with a hardwired ESP 32 gateway. I would like to upgrade from 4.1.0 to 4.1.3, but if I try and do it from the webpage, halfway through loading it says HTTP Update failed. Any ideas? Is it possible to update this from the gui?


I do not think you can update the wired version from the GUI you have to do it via a programmer.
There is info on the upgrade page I think (where you get the upgrade file)


Thanks for taking the time to reply John. It’s odd because on this page wired_ethernet it clearly states under FIRMWARE that you can update from the GUI

I don’t know this exactly, but a similar working Opensprinkler can only be operated wired, update only works wirelessly with the local AP, Ethernet Fable disconnected, restarted.

That ESP8266 can only have one network connection, either wired or wireless.

That is a good thought - Maybe I’ll try it in wireless mode…


this is the info from the update area where you should get your firmware file

  • Olimex ESP32 Gateway (Wired Ethernet) - can run V3.x and V4.x firmware - use esp32-gateway-e.bin - NOTE: Ethernet gateway does not support HTTP update, FW must be uploaded via micro usb and esptool, see docs.
