Smart homes are increasingly popular and offer users multiple benefits, such as increased security, entertainment, health, and energy efficiency. But smart homes also raise ethical challenges. Analyzing ethical risks in smart homes requires an approach that can reveal and analyze the complex consequences of unethical IoT use. Such an analysis, however, is cumbersome and requires including many aspects and stakeholder perspectives. There is a lack of methods to analyze smart homes ethically and document such research results for continual evaluation over time as the smart home and our understanding of its ethics inevitably evolve and change. This work aims to design a workshop methodology to support systematic ethical analyses of smart homes. It builds on previous work considering smart homes as digital ecosystems to contextually examine ethical risks and challenges. A group of research participants were asked to undergo the workshop to evaluate its usefulness in supporting ethical discussions and documenting insights systematically. The results show the feasibility of the workshop design in conducting ethical analyses and eliciting system requirements for smart homes. Several unethical use cases are discussed, such as IoT gaslighting and surveillance concerns related to child users.
