EMS-Wiki

Buderus Logamatic EMS and EMS+ bus Wiki for Bosch, Buderus, Nefit, Junkers, Worcester devices.

Other names or versions of the EMS bus are EMS+, EMS Plus, EMS2, EMS2.0, Heatronic and Heatronic 3.

Junkers and Nefit also call it '2-Draht-Bus-System' or '2-wire-bus'.

This repository is a collection of EMS protocol- and device documentation gathered from public sources like other Github repositories and of course my older documentation.
Will be filled in bit by bit.


See the Documentation folder for all information.
