How did ithinx help:

The Viessmann connectivity strategy envisaged 100% integration of connectivity. Therefore, a highly integrated solution had to be developed that not only supports the end customer and heating installer, but also customer service and, above all, value-added services such as energy management.

The solution had to be durable, highly integrated, cost-optimised and multi-protocol capable and, above all, also have a high transmission and reception performance.

ithinx developed an RTOS and Linux platform for Viessmann, taking into account the planned application and the costs The patented PCB antenna ensures excellent performance in the new solutions, regardless of the location of the device installation in the basement.

“Viessmann had high requirements for a highly integrated connectivity solution for extensive applications. After the market launch in 2018 was successful, we have further developed and optimised the solution together with ithinx over the last few years. The patented antenna has brought another major optimisation in the area of transmission and reception performance. Since 2022, this antenna has enabled Viessmann to make installation in buildings much easier and to achieve higher quality in terms of connectivity.”
