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.
Please check out the project pages of proddy https://github.com/emsesp/EMS-ESP and his ReadMe and also Victor-Mo's page https://github.com/Victor-Mo/IRT-ESP and ReadMe.
EMS/iRT-ESP is an open-source firmware for the Espressif ESP8266 and ESP32 microcontroller that communicates with EMS (Energy Management System) and iRT-bus based equipment from manufacturers like Bosch, Buderus, Nefit, Junkers, Worcester and Sieger.
This is the firmware for the ESP8266, known as version 2. Proddy has 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.
