From a hundred systems to an ecosystem – a unique partnership for the properties of the future

Digitalization is no longer a sideline, it is now a strategic core. Together with Kiona and Hemsö, our subsidiary Oaks is running a project that is unique in the industry: to create an open ecosystem where hundreds of different control systems can speak the same language. Through this partnership, we are taking a major step towards sustainability, efficiency and innovation.
