2.1. The Advent of Smart Homes
- Automation: the ability to accommodate automatic devices or perform automatic functions;
- Multi-functionality: the ability to perform various duties or generate different outcomes;
- Adaptability: the ability to learn, predict and meet the needs of users;
- Interactivity: the ability to allow the interaction among users;

2.3. The Role of the ICTs in Smart Homes and the Smart Grid
2.4. The New Role of the Users
3. Aim of the Work
4. Classification Criteria for the Selection of Smart Home Technologies
- Data collection: the technology allows the collection of all relevant data and provides access to them;
- Data processing: the technology allows the processing and analyzing of relevant data and can combine them;
- Data representation: the technology allows the relevant data to be made accessible to the users;
- Control and interaction capabilities: the technology enables users to access the status and monitor the functions of related technologies (bidirectional communication and interaction).
- Direct: the more immediate the feedback is, the more effective it is, but it requires a certain degree of knowledge and preparation from users;
- Personalized: the way of presenting data is customized to end-users’ needs;
- Comparable: end-users can compare their actual electricity usage with benchmarks as well as with their historical data;
- Flexible: the feedback technology needs to be continually improved, in response to users’ suggestions and requests.
- Systemic: the house exists in a systemic context, and the data, retrieved by means of a smart grid, are presented at an individual household level and compared with the average system performance .
- Gamification: the feedback is presented by using elements and concepts that are typical in computer games and is often integrated in a graphical user interface (GUI).
5. Review of the Technologies for Smart Homes
- Integrated wireless technology (IWT);
- Home energy management system (HEMS);
- Smart home micro-computers (SHMC);
- Home automation (SHS/HA).
5.1. Integrated Wireless Technology and Network
5.2. Home Energy Management
- The increased savings for both users and utilities providers;
- A reduced peak-to-average ratio and peak loads;
- They can include local energy production from renewable sources;
- They allows the household to be inserted in a systemic context, as a separate local grid, and allow it to be connected to the outside world, i.e., creates a smart grid;
- They allow for historical comparisons of home energy usage.

6.1. Challenges Related to Smart Home Technologies
6.2. Challenges, Benefits, and Motivations Related to the Users
- Rationalizing the amount of energy required from controllable loads: smart grids enable providers to better control and plan production and to adjust the price levels of electricity. Previous studies have systematized approaches to home energy management, which may belong to one or any mix of the following three categories: (i) a technology-oriented approach; (ii) an economically-oriented approach or (iii) an environmentally-oriented approach.
- Wisely scheduling running times for smart appliances that are likely to be shifted in time. Households’ involvement in cutting their overall energy demand and the evening peaks in energy usage is still being explored. Currently, a lot of interest is being directed to making homes more flexible energy users. This flexibility aims to modify households’ load shape thanks to feedback on real-time energy usage and an indication from them of which tariff information they found useful in relation to optimizing their energy costs.
- Turning themselves into potential carbon-free generators of energy, through the use of renewable resources: so far, the focus of smart grid technologies has been on integrating RES into the grid to reduce the cost of power generation. Integrating these resources requires storage systems. Load/generation shifting can be used by customers, utility providers, or renewable power producers to take advantage of the different electricity rates available at various times of the day .
