Smart Home – intelligent connectivity for comfort, security and energy efficiency
The Smart Home is on the rise. With the increasing range of suitable devices and professional system solutions, connecting one's own four walls is becoming
ever easier. What exactly is a Smart Home, for which areas is interconnectivity recommendable and why maintenance-free wireless technology is particularly
well suited for this purpose? Just read on for the answers to these questions.

How does a Smart
Home work?

A professional Smart Home is an intelligent ecosystem thatinterconnects individual components (sensors and actuators).
A control center (hub or gateway) processes the information collectedby the sensors and transmits the corresponding commands to theactuators (e.g. lamps or radiator valve attachments).
The system can be managed remotely via a wall display, smartphoneor tablet. In addition, the user can also operate by switch or remotecontrol which is locally related to the specific room.

Important: Stand-alone smart products
such as voice assistants or smart meters
do not make up a Smart Home.

What advantages doesa Smart Home have?
ComfortThe connected home can be adjusted in terms oftemperature and lighting according to the wishes of its
residents. The temperature is controlled room by room
based on occupancy, preset routines or weather forecast.
Other products analyse the heating behaviour of theoccupants and adapt themselves after a self-learning
phase. The air quality is continuously monitored by fixedparameters (e.g. CO2 concentration). And the lighting canalso be controlled according to room occupancy, time of
day or defined scenarios.

Security
The connected home controls itself and is therefore safer.
Motion, smoke and glass breakage sensors work in
conjunction with surveillance cameras and alarms.
No danger escapes them. They register window breakage or
movement around the house and trigger an alarm.
And anyone who wonders whether all the windows and doors
are closed can check this on the smartphone in real-time.

EnergySmart heating control saves energy thanks to intelligent
connectivity in which thermostats react to environmental
stimuli such as brightness, movements or temperature.
Thus, for example, the heating valve switches down automatically when the room is empty or a window is open.
It also maintains a preset comfortable temperature as soon
as it is reached. Central functions such as a main switch
also save energy. With just one click all electrical appliancesin the household are deactivated.

What are the benefits ofopen radio standards in termsof interoperability?
In contrast to self-contained Smart Home systems based on
proprietary communication standards, systems based on open
wireless standards such as EnOcean increase flexibility and enable
seamless expansion of the Smart Home and automation ofprocesses.

ISO/IEC 14543-3-10 / 868 MHz

The EnOcean wireless standard (ISO/IEC 14543-3-10) is designedfor solutions with particularly low energy consumption and energy
harvesting. In Europe, the wireless radio technology operates on
the 868 MHz frequency channel, which is only approved for pulse
signals.
