**EMS-ESP** is an open-source firmware for the Espressif ESP32 microcontroller that communicates with **EMS** (Energy Management System) based equipment from manufacturers like Bosch, Buderus, Nefit, Junkers, Worcester and Sieger. It requires a small gateway circuit to interface with the EMS bus which can be purchased from <https://bbqkees-electronics.nl> or custom built.
## **Features**
- A multi-user, multi-language secure web interface to change settings and monitor incoming data
- A console, accessible via Serial and Telnet for more advanced monitoring
- Native support for Home Assistant, Domoticz and openHAB via [MQTT Discovery](https://www.home-assistant.io/docs/mqtt/discovery/)
- Can run standalone as an independent WiFi Access Point or join an existing WiFi network
- Easy first-time configuration via a web Captive Portal
- Support for more than [110 EMS devices](https://emsesp.github.io/docs/#/Supported-EMS-Devices) (boilers, thermostats, solar modules, mixer modules, heat pumps, gateways, switches, heat sources)
## **Documentation**
For the complete documentation on how to install, configure and get support visit the [EMS-ESP Wiki](https://emsesp.github.io/docs).
