Esp32-web-interface
The Olimex MOD-WIFI-ESP8266 is usually used to provide a web interface to configure and monitor various EV conversion components found here. E.g. inverters, chargers, etc.
An alternative to this is to use an esp32 based module. You can find a port of the esp8266 firmware for esp32 in Bedz02 Github repo here.

Ethernet / Wired Option
WiFi can struggle to operate well when it uses the small antenna found on these boards and is buried under multiple layers of metal inside a car. Some people might prefer to use a wired option instead. One way to do this is to use an esp32 board which includes an ethernet port and connect to the web interface this way.
You can find a modified version of the esp32 firmware which includes ethernet support in this Github repo.
Installation
- Clone/download the git repo.
- Install platformio on your laptop/desktop
- Build and then upload the firmware to your ESP32 board. See more info here.
Supported Hardware
- Olimex ESP32-POE-ISO - tested and confirmed working.
