Evaluation of Smart Home API with a developed application to a heating system

Abstract: Many companies are trying to be the central part of the smart home. By using public APIs you can integrate with other enterprise solutions and devices while you by yourself does not have to develop systems that are already on the market. This report consists of three parts in order to solve the integration of public APIs to an existing device in a heating system in smart home. The first part is a comparison of four different public APIs. The second part deals with the development of a couple system architectures for a general solution of how to add various public APIs in an easy and convenient way. The last part is an implementation of one system architecture to an existing system.
