Internet of Things (IoT) technologies are already playing an important role in our daily activities as we use them and rely on them to increase our abilities, connectivity, productivity and quality of life. However, there are still obstacles to achieving a unique interface able to transfer full control to users given the diversity of protocols, properties and specifications in the varied IoT ecosystem. Particularly for the case of home automation systems, there is a high degree of fragmentation that limits interoperability, increasing the complexity and costs of developments and holding back their real potential of positively impacting users. In this article, we propose implementing W3C’s Web of Things Standard supported by home automation ontologies, such as SAREF and UniversAAL, to deploy the Living Lab Gateway that allows users to consume all IoT devices from a smart home, including those physically wired and using KNX® technology. This work, developed under the framework of the EC funded Plan4Act project, includes relevant features such as security, authentication and authorization provision, dynamic configuration and injection of devices, and devices abstraction and mapping into ontologies. Its deployment is explained in two scenarios to show the achieved technology’s degree of integration, the code simplicity for developers and the system’s scalability: one consisted of external hardware interfacing with the smart home, and the other of the injection of a new sensing device. A test was executed providing metrics that indicate that the Living Lab Gateway is competitive in terms of response performance.

The present work seizes the opportunity to counter IoT technology fragmentation that the World Wide Web Consortium is offering with the upcoming standard Web Of Things. A gateway service based on this standard and an air quality manager sensor were designed and implemented in a Smart Home with the aim to develop a tool to manage this critical parameter and improve people´s quality of life. The system proved to be able to report and manage the Smart Home devices to reduce Fine Particulate Matter concentration on demand and in real time, also allowing to record data to be consulted by the Smart Home users. The technology produced is agnostic, scalable and replicable in other environments and contexts such as industry, healthcare and Smart Cities among others.
