Yes, the esp32-gateway-ethernet FW is now on the releases page. The full docs on how to connect and upload to the esp32-gateway-ethernet boards can be found here:

# 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
