Heating, ventilation and air conditioning (HVAC) systems can include temperature and humidity control, including fresh air heating and natural cooling. An Internet-controlledthermostat allows the homeowner to control the building's heating and air conditioning systems remotely. The system may automatically open and close windows to cool the house. Today - there are also dedicated gateways that connect advanced VRV / VRF and Split HVAC Systems with Home Automation and BMS (Building Management Systems) controllers for centralized control and monitoring. In addition, such gateway solutions is capable of providing remote control operation of all HVAC indoor units over the internet incorporating a simple and friendly user interface.
Home automation products can be used for something as simple as adding Multiway switching to existing electric lighting circuits, or can include very complex interactions with other systems.
A Lighting control system can be used to switch lights based on a time cycle, or arranged to automatically go out when a room is unoccupied. Some electronically controlled lamps can be controlled for brightness or color to provide different light levels for different tasks. Lighting can be controlled remotely by a wireless control or over the Internet. Natural lighting (daylighting) can be used to automatically control window shades and draperies to make best use of natural light.
On the residential market, Z-Wave, Insteon and the older X10 protocol are very commonly used for lighting automation.
This category includes audio and video switching and distribution. Multiple audio or video sources can be selected and distributed to one or more rooms and can be linked with lighting and blinds to provide mood settings.
Automatic control of blinds and curtains can be used for:
- Presence simulation
- Temperature control
- Brightness control
- Glare control
- Security (in case of shutters)
A household security system integrated with a home automation system can provide additional services such as remote surveillance of security cameras over the Internet, or central locking of all perimeter doors and windows.
With home automation, the user can select and watch cameras live from an Internet source to their home or business. Security systems can include motion sensors that will detect any kind of unauthorized movement and notify the user through the security system or via cell phone.
The automation system can simulate the appearance of an occupied home by automatically adjusting lighting or window coverings. Detection systems such as fire alarm, gas leak, carbon monoxide, or water leaks can be integrated. Personal medical alarm systems allow an injured home occupant to summon help.
An intercom system allows communication via a microphone and loud speaker between multiple rooms. Integration of the intercom to the telephone, or of the video door entry system to the television set, allowing the residents to view the door camera automatically.
Journalist Bruno de Latour coined the term domotic in 1984. Domotic has been recently introduced in vocabulary as a composite word of Latin word domus andinformatics,[and it refers to intelligent houses meaning the use of the automation technologies and computer science applied to the home.
The term covers a range of applications of information technology to the problems of home automation.
Domotics is the study of the realization of an intelligent home environment.
Digital Home includes home automation, multimedia, telecommunications, e-commerce, etc. through home networks Domotics and home automation means that systems talk toeach other for improved convenience, efficiency and safety.
