**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 fork is based on proddys and victor-mo work on EMS und iRT gateways.
Both are not longer maintaint for the ESP8266, so I decided to learn a little and merge both capabilitys to one project and also extend the cababilitys of the software.

This is the firmware for the ESP8266, known as version 2. We've since moved to the ESP32 platform with v3 which opens up many more possibilities for additional features. Make sure you check out <https://github.com/emsesp/EMS-ESP32> and look at the [demo](https://ems-esp.derbyshire.nl).
Please check out the project pages of proddy <https://github.com/emsesp/EMS-ESP> and his [ReadMe](https://github.com/emsesp/EMS-ESP#readme) and also Victor-Mo's page <https://github.com/Victor-Mo/IRT-ESP> and [ReadMe](https://github.com/Victor-Mo/IRT-ESP#readme).

## **Important: This version will be restricted to maintenance releases only!**
