SAMSON TROVIS controllers

trovis-modbus Wiki

This project as a whole (library + HA integration) provides a practical control and monitoring model for the majority of the TROVIS functions.

It is intended for automatic device discovery, operational monitoring, and occasional fine adjustment of already commissioned heating systems.

It does not attempt to reproduce every single controller menu, parameter level, special function, register or coil (there are thousands of them). It is also not meant as initial commissioning tool for new heating systems; for this, please use SAMSON's TrovisView Windows application instead (you can download it for free from the SAMSON Web page).
