# OpenEVSE WiFi ESP32 Gateway v4

> **_NOTE:_** Breaking change! This release reccomends a minimum of [7.1.3](https://github.com/OpenEVSE/open_evse/releases) of the OpenEVSE firmware, features including Solar Divert and push button menus may not behave as expected on older firmware.

- *For the older WiFi V2.x ESP8266 version (pre June 2020), see the [v2 firmware repository](https://github.com/openevse/ESP8266_WiFi_v2.x/)*

- **For latest API documentation see the new [Spotlight.io OpenEVSE WiFi documentation page](https://openevse.stoplight.io/docs/openevse-wifi-v4/ZG9jOjQyMjE5ODI-open-evse-wi-fi-esp-32-gateway-v4)**

![main](docs/main2.png)

The WiFi gateway uses an **ESP32** which communicates with the OpenEVSE controller via serial RAPI API. The web UI is served directly from the ESP32 web server and can be controlled via a connected device on the local network.

**This FW also supports wired Ethernet connection using [ESP32 Gateway](docs/wired-ethernet.md)**
