A smart interface for controlling and monitoring HVAC units. An innovative solution born from the collaboration between areakappa and Siemens.

An Italian innovation that conquered the global HVAC market
Areakappa proposed to Siemens HQ an innovative HMI solution for controlling and monitoring HVAC units (chillers, AHUs, etc.) via mobile app (Android and iOS) and cloud, equipped with Siemens Climatix controllers. The solution enabled both on-board and remote control.
After a few years of development and refinement, the prototype became an official Siemens product named "smartHMI", integrated into the Climatix line.
Today, Siemens Climatix smartHMI is installed in thousands of HVAC units worldwide, supplied to major Siemens OEM customers including:
Important note: Siemens Climatix smartHMI is an official Siemens product. It was conceived by one of areakappa's founding partners and proposed to Siemens, which adopted it as part of its own product portfolio.
