**4.2 Interoperability issues**

IoT devices and systems can be complex and varied, making interoperability between devices and systems difficult. This can create challenges in integrating IoT

devices with energy management systems, leading to additional costs and complexity [3]. Addressing this challenge requires the development of standard communication protocols and data formats to ensure interoperability between different devices and systems.

### **4.3 Privacy concerns**

IoT devices can collect and transmit large amounts of data, including personal data, raising privacy concerns [10]. Therefore, ensuring the privacy of individuals' data is critical to ensure trust and confidence in IoT-enabled energy management solutions. This can be achieved through data encryption, anonymization techniques, and data minimization strategies.

### **4.4 Lack of standardization**

IoT is still a relatively new technology, and there needs to be more standardization in many areas, including data formats, communication protocols, and security standards. This lack of standardization can challenge IoT-enabled energy management solutions' interoperability, security, and reliability [3]. Addressing this challenge requires the development of common standards and guidelines to ensure consistency and interoperability between different IoT devices and systems.

These challenges can impact the implementation of IoT in energy management by increasing costs, reducing reliability, and decreasing user trust and confidence.
