Home automation is an up and coming trend that the public looks for in residential houses, apartments, and commercial businesses. Although many techniques used in building automation (such as light and climate control, control of doors and window shutters, security and surveillance systems, etc.) are also used in home automation, additional functions in home automation can include the control of multi-media home entertainment systems, automatic houseplant watering and pet feeding, automatic scenes for dinners and parties, and a more user-friendly control interface.
Typically, a house during construction has more room for more automation due to the accessibility of the walls, outlets, and storage rooms. Wireless is commonly used when a house has already been built and you don’t want to modify your walls. These control wires run to a controller, which will then control the environment.
Home wiring History
Traditionally, homes have been wired for four things; power, telephones, cable TV outlets, and a doorbell.
Typically, components and wiring are kept within a closet and/or patch panels.
Home automation has been around since WWI. It all started with the first television remote. In 1893 a remote was originally used in WWI to control motorboats.[1] From there, the evolution of controllers and automation has been growing and still continue to grow to this day.
Standards and bridges
Specific domotic standards include INSTEON, X10, PLC BUS, KNX (standard), System Box, LonWorks, C-Bus, SCS BUS with OpenWebNet, Universal powerline bus (UPB), UPnP, ZigBee and Z-Wave that will allow for control of most applications. Some standards use communication and control wiring, some embed signals in the powerline, some use radio frequency (RF) signals, and some use a combination of several methods. Control wiring is hardest to retrofit into an existing house. Some appliances include USB that is used to control it and connect it to a domotics network. Bridges translate information from one standard to another (eg. from X10 to European Installation Bus).

Effects
In extreme installations, rooms can sense not only the presence of a person but know who that person is and perhaps set appropriate lighting, temperature and music/TV taking into account day of week, time of day, and other factors.
Other automated tasks may include setting the air conditioning to an energy saving setting when the house is unoccupied, and restoring the normal setting when an occupant is about to return. More sophisticated systems can maintain an inventory of products, recording their usage through an RFID tag, and prepare a shopping list or even automatically order replacements.
Some practical implementations of home automation are for example when an alarm detects a fire or smoke condition, then all lights in the house will blink to alert occupants. If the house is equipped with a home theater, a home automation system can shut down all audio and video components to alert the user to a possible fire or a burglar.
System
The elements of a domotics system are:
- hardware controllers or software controllers example software controller
- sensors
- actuators
Architecture
From the point of view of where the intelligence of the domotic system resides, there are three different architectures:
Centralized Architecture: a centralized controller receives information of multiple sensors and, once processed, generates the opportune orders for the actuators.
Distributed Architecture: all the intelligence of the system is distributed by all the modules that are sensors or actuators. Usually it is typical of the systems of wiring in bus.
Mixed Architecture: systems with decentralized architecture as far as which they have several small devices able to acquire and to process the information of multiple sensors and to transmit them to the rest of devices distributed by the house.

Tasks
HVAC
Heating, Ventilation and Air Conditioning (HVAC) solutions include temperature and humidity control (climotics).
HVAC, is one of the most important aspects to a homeowner and to his/ or her smart home. Having a computer network installed at your home or business lets you do you much more than simply surf the Web. An Internet-controlled thermostat, for example, can both save you money and help the environment, by allowing you to control the building's heating and air conditioning systems while the consumer is away.
Lighting
Lighting control systems involves aspects related to controlling electric lights.
- Extinguished general of all the lights of the house
- Automation of switched off / ignition in every point of light
- Regulation of the illumination according to the level of ambient luminosity.
Lutron Lighting has products that can be used in many applications. This includes; movies, meal times, wake up/ sleep times, entertainment, and even clean up mode. Users and control system lights from a tabletop master control, a wireless controller, or from individual wall dimmers. Schedule landscape lighting to automatically turn on at dusk. Lighting control can change room ambience, save energy by making use of a room’s natural light.
Natural lighting
Natural lighting control involves controlling window shades, LCD shades, draperies and awnings. Recent advances include use of RF technology to avoid wiring to switches and integration with third party home automation systems for centralized control.
Audio
Major companies associated with Audio Distribution include: Crestron, Russound, NuVo, and Niles.
- There are three components that allow the consumer to listen to audio throughout your home, or business:
This category includes audio switching and distribution. Audio switching determines the selection of an audio source. Audio distribution allows an audio source to be heard in one or more rooms. This feature is often referred to as 'multi-zone' audio.
Video
This includes video switching and distribution, allowing a video source to be viewed on multiple TVs. This feature is often referred to as 'multi-zone' video.
Integration of the intercom to the telephone, or of the video door entry system to the television set.
Security
Control and integration of security systems.
With Home Automation, the consumer can select and watch cameras live from an Internet source to your home or business. Monitor a front door or gate; watch people by a swimming pool; or check on someone in a room. You can control security cameras and watch what's going on around a house or business right from a Monitor or touch panel.[2]. Security systems include motion sensors that will detect any kind of unauthorized movement and notify you through the security system or via cell phone.
This category also includes control and distribution of security cameras (see surveillance).
- Detection of possible intrusion
- Simulation of presence.
- Detection of fire, gas leaks, water leaks (see fire alarm and gas alarm)
- Medical alert. Teleassistance.
- Precise and safe closing of blinds.
Intercoms
An intercom system allows communication via a microphone and loud speaker between multiple rooms.
- Ubiquity in the external control as much internal, remote control from the Internet, PC, wireless controls (p.ej. PDA with WiFi), electrical equipment.
- Transmission of alarms.
- Intercommunications.
Robotics
- Control of home robots, using if necessary domotic electric beacon.
- Home robot communication (i.e. using WiFi) with the domotic network and other home robots.
Costs
- An automated home can be a very simple grouping of controls, or it can be an automation extravaganza where just about anything that is plugged into electrical power is remotely controlled. While there is no way to know what the consumer wants, their only limit to a smart home is his or her budget. Costs mainly include; equipment, components, furniture, and custom installation.
Other systems
Using special hardware, almost any device can be monitored and controlled automatically or remotely.
Including:
- Coffee pot
- Garage door(s)
- Pet feeding and watering
- Plant watering
- Pool pump(s) and heater, Hot tub and Spa
- Sump Pump (need info and links)
