According to the guideline „Wireless & Self-powered IOT“ EnOcean and Digital Concepts demonstrated how maintenance-free solutions for building automation and the Internet of Things (IoT) lend new dimensions to services and business models, intelligent buildings into cognitive buildings. Visitors could experience battery-free radio switches, sensors and actuators as well as maintenance-free radio sensor solutions on the basis of the EnOcean radio standard in the sub-1 GHz range (ISO / IEC 14543-3-1x). The battery-powered devices enable flexible, maintenance-free applications for worldwide use in building automation, smart homes, LED lighting control and industrial applications. Together with leading industry partners, such as IBM and other members of the EnOcean Alliance, EnOcean is working on the development of innovative building solutions for the Internet of Things. Combined with intelligent IoT systems such as IBM’s Watson IoT platform, battery-based sensor solutions help optimize the use of buildings, develop new service models, and make buildings more flexible, energy-efficient, and cost-effective.
