Heat & Cold
The field of Heat and Cold, better identified with the acronym HVAC (Heating, Ventilation and Air Conditioning), is the most attracted by the technological evolution and, more specifically, by wireless Wi-Fi technology.
There are several reasons, but surely all reasonable and interesting.
In fact, while before a control system of conditioning was limited to the environment in which it was included, it now has to be open, integrated with other systems, accessible, comfortable.
Every single source of heat or cooling can now be controlled and can communicate with the outside world, even through personal devices (smartphones and tablet).
