**5. Challenges and opportunities**

While the general landscape of DT-enabled smart healthcare at home looks promising and our case study validates its feasibility, there are many open questions yet to be explored. Here, we identify the most critical challenges along with the opportunities in this raising area:


the target of various unauthorized and even malicious agents. Adequate measures such as encryption, access controls, and strict data handling policies should be implemented to ensure the privacy and confidentiality of patient information.
