**EMS-ESP** is an open-source firmware for the Espressif ESP8266 and ESP32 microcontroller that communicates with **EMS** (Energy Management System) based equipment from manufacturers like Bosch, Buderus, Nefit, Junkers, Worcester and Sieger.

This is the firmware for the ESP32. Compared to version 2 for the ESP8266, this release has

- Ethernet Support
- Pre-configured board layouts
- Writing values directly from the Web UI
- Mock API server for faster offline development
- Expose to more commands, via MQTT
- Improvements to Dallas sensors, Shower service

This version is the latest development track, where as v2 is in maintenance mode.
