1) Introduction: what is meant by home automation
Home automation is a new way of conceiving and designing domestic systems.
Home automation is the result of an evolution of technological systems: in the houses of the past the systems were mainly made up of a light point and therefore a home automation system would have been useless. But with the passage of time and following improvements in the plant and technological fields (automatic shutters, air conditioning systems, burglar alarms, video surveillance methods, audio systems…) it has been possible to introduce the use of home automation.
The most particular aspect is interdisciplinarity, because the topic in question deals with very different themes, from networks to security systems, lighting, air conditioning and even photovoltaics. The problem is to understand all these different aspects and merge them into a single system: home automation as a technique is based on this operation; in fact today more and more credit and importance is given to the professional figure of the system integrator, who is in charge of the home automation system.
The term home automation alludes to a "computer house", which can be managed using technological tools.
On a technical level, home automation is a digital system for managing domestic systems. Check all systems: electrical, air conditioning, security, acoustic, lighting, etc. . The characteristics that distinguish a home automation system are control, integration and digitization. Control since the system itself has no autonomous function, it is simply independent. The integration allows the different subsystems to communicate with each other; finally, digitization allows the various systems to interact in the form of bits.
2) Costs, advantages and problems of the home automation system
Home automation therefore appears to be something well defined and brings numerous benefits. For example, it allows you to rationalize energy consumption related to electricity and gas, increases the safety of the electrical system and of the entire house, and overall allows you to give an active response to any emergencies, allows an improvement in comfort, through control centralized and not of the plant in all its subsystems, through computer control via the internet.
In the past, each device had its own remote control and this created a lot of confusion. Home automation avoids these problems also thanks to the increasing use of tablets and smartphones through which everything can be controlled. In this way everything is more easily and rationally managed.
The system is easy to use and is not dangerous. It always works, even in the presence of any faults, and is immune to malfunctions.
Of course, the costs are not to be underestimated, since it is necessary to consider how much the home automation system affects the total cost of the systems. There are various methods with which a home automation system can be created. For example, a system that is limited to the control of lights and loads (basic level) has an impact of about 10-20%; if the plant is larger, the cost will also be higher. The cost also changes depending on the type of system adopted, since there are various technologies to create a home automation system. A complete system within a standard 120 sq m apartment can account for up to 50% of the total cost.
