Smart Home devices are IoT (Internet of Things) enabled devices used to enhance wellbeing within the home environment. Around 63% of IoT devices are Smart Home devices. Although IoT devices have been available for a while, recent studies show that acceptance of Smart Home devices is limited to innovators and early adopters. Interestingly it has been observed that some categories of Smart Home devices are more popular suggesting that there is variance in acceptance of IoT devices. This research investigates the differences in consumer acceptance of various Smart Home device categories. Smart Home devices were categorised into three categories: 1) Technology and Entertainment; 2) domestic appliances; 3) housekeeping devices. The research focuses on the investigation of the reasons and factors influencing behaviour intention and use behaviour for each of the defined Smart Home device categories. An adapted version of the Unified Theory of Acceptance and Use of Technology (UTAUT2) model was used to study technology acceptance. The PLS-SEM technique, facilitated by SmartPLS 3.0 software, was used to perform the analysis. Our study confirms that behavioural intention to adopt and use Smart Home devices, and the factors driving adoption, varies between Smart Home IoT categories. Accordingly, it is vital to consider device type distinctively when considering Smart Home IoT adoption and usage.
