In the field of human-computer interaction, the majority of domestic IoT and smart devices run on proprietary software that possess limited technical properties and predetermined functionalities. As practices of building, modifying, and making IoT applications grow, this thesis follows an open-source approach to IoT to investigate the relationships of humans and things in a domestic setting. As a result of this material exploration, proprietary frameworks for interactions with smart devices are challenged through speculative scenarios, that include diverse instances of human-things interactions. Thus, a research through design methodology is suggested to support series of experiments, conducted to explore instances of perceived intelligence of these open-source hardware, without the use of advanced computational systems as proprietary devices entail. The suggested process is the creation of a speculative design artifact that combines hacking practices, to support designers in generating insights and to further iterate on possible open-source IoT interactions.
