In recent years more and more people have decided to make their homes smart by installing a home automation system. Home automation’ means equipping your home with automatic functions. There are several levels of home automation that change according to the needs and tastes of the customer, where they can be simple by integrating a few systems such as automatic shutters and a few appliances such as the automatic coffee machine, go up a level to integrate automated air conditioning and heating systems.
Finally, you can get to total home automation where all the functions of the house are automated (close the locks, activate an alarm system and so on). Obviously, the greater the automation of the house, the higher the price.
Beyond the price of the home automation system, the installation of a home automation system is not an operation that you can do groping in the dark, because there are several questions to answer, choose which is the best system and so on. The first of the most important questions is whether to choose a wireless or wired home automation system.
Now that we are accustomed to the ubiquitous wi-fi connections everywhere and the cables we use to charge our devices, you may think that a wired home automation system is an obsolete thing and now outdated by the new wireless systems
However, it is a misconception, since both have pros and cons. A home automation system is defined as weird if all the devices connected to the control unit of the system communicate with it through a wiring system that passes through the walls of the house or otherwise of the room that you intend to domotize.
Cable home automation systems can have two modes of communication, one called serial and the other IP. Serial connection is a good solution to control all the main functions of the house (automatic air conditioning and heating, alarm systems, electronic shutters and so on), however it must be said that not all appliances support serial connection. So the second solution is via IP where the network cable travels on the Internet data of the house and also the commands of the Smart systems, so you connect directly to the modem of the house.
A wired home automation system involves the passage of cables inside the walls of the house, then by force of the masonry work. It’s An excellent solution in new homes there are still not finished or if they are planning renovation work. So the project of domotics wired must be done upstream, otherwise it is difficult to change.
Wired home automation, unlike wireless, has the advantage of being much more reliable in the communication of devices and carry more data, electricity and power (so the largest and most effective systems must be designed in wired).
Despite the many points in favor of wired home automation, that wireless has many strengths. A home automation system is defined as wireless when only the control unit (and if necessary a few other pieces) are connected through a wiring system.
Wireless home automation devices communicate with the control unit through the use of different wireless technologies, emitter and receiver systems present in the devices, in the control unit and in some cases at intermediate points if it is too difficult to reach the control unit directly.
Before going into detail there is a specification that it is important to do. When we talk about wireless home automation we mean only the communication of the devices connected to the system. All home automation installations are wired in one way or another, because at least the home automation control unit must be connected to the home power supply. Subsequently, once the ‘brain’ of the system has been installed, then it is possible to choose whether the other pieces should also be wired or communicate through wireless technologies.
Wireless home automation uses different communication technologies that can be Z-Wave, ZigBee, Bluetooth and IR. The first two use a bridge system, sending the signal to the intermediate receiver that makes it bounce to the control unit, while the other two provide a direct connection and much less reliable.
The advantage of choosing a wireless home automation system, compared to the wired one, is first of all in the cost. Installing appliances and devices of this type is in fact much cheaper since the cost of the home automation system is limited to the purchase of the appliance.
I dispositivi wireless si possono comprare anche in un secondo momento quindi c’è sempre la possibilità di ampliare il proprio impianto. L’impianto domotico wireless inoltre ha il vantaggio di non richiedere dei grossi interventi fisici alla muratura della casa, com’è invece per quello cablato, alcuni possono essere limitati giusto all’installazione della centralina.
Tuttavia si deve tenere conto di un’affidabilità minore rispetto a quello cablato e gli impianti che si possono installare devono essere necessariamente meno potenti. Per esempio, è impensabile integrare sistemi wireless di irrigazione, cioè molto lontane dalla centralina.
