I’m having so much problems with wifi. My wifi infrastructure is good and I’ve tried anything this past year.
I have this wt32-eth01 board laying around and thought it would be nice if I could make it work with the openevse. I saw a post in github about it, but I can’t make it work.
Does someone had success making this board work as an ethernet controller?
It should be possible, we use the ESP Ethernet Gateway from Olimex

# Wired Ethernet
Several boards are available with ethernet hardware, which can be used as drop-in replacements for ESP8266 / ESP32 WiFi modules and are compatible with all models of OpenEVSE / EmonEVSE.
See [OpenEnergyMonitor web-store to purchase a pre-wired ESP32-Gateway module](https://shop.openenergymonitor.com/openevse-etherent-gateway-esp32/). The Ethernet gateway in our web-store will come with pre-wired power supply, serial connections, and pre-loaded with firmware for drop in replacement.
Network connection can be made with a standard Ethernet cable. For new installations it may be worth considering a power cable with integrated data connections such as the [Doncaster EV-ultra cable](http://www.doncastercables.com/cables/17/77/EV-Ultra/Power-and-data-connectivity-combined-in-one-cable/). If using such a cable, extra work will be required to attach RJ45 connector or socket at each end.
## Hardware Connections
Wiring varies depending on the board in use, in particular [this git issue](https://github.com/OpenEVSE/ESP32_WiFi_V3.x/issues/12) discusses a wiring change between revisions of the ESP32-GATEWAY board.
| Signal | EVSE wire | ESP32-GATEWAY E & F | ESP32-GATEWAY pre-E | ESP32-PoE-ISO
| :--------- | :---------- | :------------------ | :------------------ | :------------
| 5V | Red wire | 20 | 20 | N/C (powered over Ethernet)
| GND | Black wire | 19 | 19 | GND
