Internet of Things (IoT) is a new technology and it has been used in several disciplines in developed countries. In developing countries such as Jordan, the IoT smart home is provided by several companies, however, the adoption of IoT smart home has been examined in few studies. The purpose of this study is to examine the adoption of IoT smart home in Jordan. Technology-Organization-Environment (TOE) framework and Social Exchange Theory have been used to develop the conceptual model of this study. The study proposes that technological context (security, privacy, and availability) affect the behavioural intention (BI) to use IoT smart home. The study proposed that BI will have a positive effect on adopting IoT smart home. Trust in service provider was proposed as a mediator and IT knowledge as a moderator between technological context and BI of IoT smart home. The population of this study are executives in listed and non-listed companies. The study uses the random sampling. The data was collected using a questionnaire. A total of 315 responses were collected. The data was analysed using Smart PLS. The findings of hypotheses testing showed that the effect of technological context is positive and significant on BI to use IoT smart home. In addition, BI to use IoT smart home have significant effect on the adoption of IoT. Trust partially mediated the effect of technological context on the BI to use IoT smart home. However, IT knowledge did not moderate the effect of technological context on BI to use IoT smart home. Decision makers are advised to focus on the technological aspect and improve the trust in service providers.
