Smart home systems, integrating multiple devices and interaction methods, give rise to complex usability challenges. While heuristic evaluation has been a preferred method for evaluating usability across various domains, its applicability to smart home systems remains underexplored. This case study investigates the strengths and constraints of heuristic evaluation applied to smart home systems. Our results suggests that while heuristic evaluation effectively identifies GUI issues and guides expert solutions, it falls short in addressing technical and hardware intricacies unique to hybrid systems like smart homes. This study not only presents recommendations for enhancing heuristic evaluations in this evolving domains, but also offers practical insights specifically for the evaluation of hybrid systems.
