The introduction of technologies and devices to support wellbeing in dementia are often evaluated using sensing technologies in a rather tech-heavy approach. The information presented by these devices is efficiently generated and typically low maintenance but this does not come without certain caveats.By nature, sensing of any type is a probing modality. Hence the information is inquisitory and personal in one form or another. The assurance that this information is collected, managed and shared in the correct manner is essential in ensuring its acceptability. Therefore it seems apparent that careful design of the system architecture and research protocols are key to achieving these objectives. However, as with any research study there are unforeseen circumstances that emerge when operating technology within a new site, presenting new challenges while seemingly at the pinnacle of a study protocol. This can be a head-scratcher for researchers and case-specific issues can demand thinking outside the box. This study considers the specific case of a lighting technology to support the synchronisation of the circadian rhythm for people living with dementia. This represents an interesting case since the amount of research conducted in this area is scarce making standard guidelines for implementation essentially non-existent. As such, this research dissects the following themes from technical, ethical, logistical and coordination issues often present when implementing a new technology in a care home. 1) Technical: The issues of networking and gateway communications are discussed alongside the question of data. How do we ensure it is of the required quality? Is it consistently transferred and stored? How does it remain secure?2) Ethical: The ethical process for implementing technology in care homes is addressed, while considering the perspective of people living with dementia. The question of medical device status is outlined alongside the discussion of consent.3) Logistical/planning: A review of site survey checklists, materials and structural composition of the built environment is evaluated, alongside an insight into the adherence to site-specific requirements.4) Coordination: Implementing a research protocol requires aligning the needs of the residents and care staff in an approach that best suits them in their daily routines, therefore the coordination and communication involved in this process is also outlined.To conclude, an informal evaluation of the entire system and study design is conducted between researchers and the care home manager. The study therefore closes with an approach to revising future designs for larger scale deployments and recommendations for a step-by-step process for designing trials from the lab to care home environment.<br/
