Introduction to Home Automation

The automation of your home can be as simple as controlling light garage with a remote control, install a motion sensor for the bell to ring when someone approaches the front door, or put lights that are activated from time to time by a timer for convenience, security or to make it appear that someone is when not at home.

Carry out a project of home automation you do not have to be intimidating or too complex. In fact, many of automation products are very easy to install. Most automation products work wirelessly by radio frequency, or using the existing electrical wiring in your home. This means that home automation is as simple as plugging in modules or plug the product into an outlet without costly wiring.

In housing more than 200 square meters a repeater that amplifies the signal and makes it harder for better reception recommended. Contact your security company for a full explanation of this and other products offered.

Communication via power line is known as PLC for its acronym in English Power Line Carrier. The oldest and most common method to communicate through the house wiring is the use of a PLC with the standard X10. X10 is a communication protocol for remote control of electrical devices. Uses the power line (220V or 110V) to transmit control signals between equipment automation homes in digital format.

A PLC system is comprised of transmitters and receivers. The transmitters are devices such as control panels, clocks, remotes, and keyboards wall or computer controllers. They send a command such as attenuation, on or off the receivers.

In the standard X10, each receiver is programmed with its own identifier (ID) unique, known as house code and unit. This code is automatically learns the configuration process or manually entered. There may be up to 256 combinations of house and unit codes X10, so that each device in the home can be controlled separately.

Devices PLC can be controlled by transmitter’s manuals, timers or intelligent controllers. Thus can be programmed to turn on or off equipment or lights, depending on the time of day, amount of sunlight, detected motion, alarm conditions, etc. There are also programs that run on computers that are running 24 hours a day and provide more advanced control over the Internet.

There are a couple of things to keep in mind when installing the product PLC. When electricity comes as 220V and is divided into two phases, or legs in the electrical panel 110V, depending on the location of the transmitters and receivers, it may be necessary for good signal PLC connect a transmitter on one leg, to the transformer street and back to the receiver on the other leg.

Especially in big houses, the signal may become too weak to reach all parts of the house. In this case it may be necessary to install a “coupling phase”, these devices create a bridge between the two legs of the electrical system so that the signal can travel more easily between the legs. In the homes of more than 200 square meters, a repeater, not only to create a bridge between the two legs, but also to increase the signal it may be necessary. These products can be wired in the switch panel, or connected to a 220V outlet. A coupler or repeater X10 should be considered as a standard feature for larger homes or more complex installations. If you find that some areas of the house cannot be controlled reliably, a quick test is to try to light a stove or a hair dryer plugged into a 220V, and see if there is an improvement with a coupler or repeater.

Devices PLC also can share the power line with other devices that may interfere with the operation. For example the power supplies of computers, fluorescent lights, and televisions, VCRs, radios, fans, ovens, pool pumps or other engines. To diagnose these problems, simply turn off the switches one by one, or disconnect the devices until the problem disappears and find the culprit.

It is not enough to turn off the television or computer. You must disconnect the switch panel. Once the problem is, it must be installed a filter that plugs into the wall or wiring if necessary to isolate the device signals the power line. With a little patience and after some attempts and tests 99% of the problems are solved.
