Cleverly retrofitted, a smart home system saves energy costs, increases security against burglary – and is convenient. 

Many solutions can be operated with a swipe via the smartphone display. App thanks. The comfort gain is not very cheap.

Proven energy saving potential through smart home system


The Fraunhofer Institute for Building Physics has found that singles with a smart home system consume up to 40 percent less energy. Families save up to 17 percent. If that is not a reason for retrofitting. But beware: The specialized trade and the online shops meanwhile carry a large offer.

Therefore, the user should know exactly what he wants to do with it before installing a smart home automation system.

Heating, lighting, secure

The variety of functions is immense. In this way, not only the socket, thermostat or lamp can be controlled in a variety of ways. Other devices either switch on and off automatically according to a specific schedule or at the whim of the residents. Helpful for retrofitting is a list of all the wishes of home automation. A floor plan also makes planning easier. The sketch shows, for example, where sensors report open or closed windows, doors or shutters, a lighting control dimmers lamps, radiator thermostats and air conditioning regulate the room temperature or the networked washing machine is.

Operation of the smart home system


Thoughts should also make smart home fans aware of the nature of the controls. So there are solutions that work with smartphone and tablet, some accept commands via special switches and touch displays or by voice.

It is important that the current functions and settings of the smart home are clearly displayed – for example on a screen. Also of importance: How should the components be linked? Some systems exchange power, others via cables. For retrofitting a radio-based smart home is particularly convenient

Open or closed system?


Smart home systems are currently in demand. That calls several providers on the plan. Accordingly diverse is the technology behind it. To distinguish here are so-called open from closed systems. Open variants are supported by different manufacturers. That is, their products understand the same language and work together.

Examples of such overarching standards . A closed system, however, is not as sociable, but works only in the own cosmos of the provider. The combination with external devices is not intended. So here you tie yourself to a product line. Although providers promise smooth installation and functionality, they are not as flexible as open systems.

In any case, a smart home system has its price. For a fully equipped version several thousand euros are due. A loan helps to shoulder the costs. In return, there is a system that leaves nothing to be desired in modern residential and security technology.

Switch on the washing machine remotely, control the heating on the way, inspect the peephole from the sofa, switch the light on and off with a gesture or check monitoring systems far from home – there are no limits to today’s smart home.
