Home automation brings together knowledge and techniques from IT, telecommunications and automation to apply them in building management. This convergence of techniques designs a system allowing remote management or programming of actions in a habitat. For example, you can program the watering of your lawn in your absence, open and close your blinds at the press of a button or even program the operation of the heating remotely. A home automation installation has the advantage of setting up sequences of automated actions or scenarios. For example, you leave your home to work and, at the touch of a button, you initiate an “absence” sequence to: close the shutters, turn off the lights and switch off the previously selected electrical appliances and thus lower the temperature of the rooms.
