Let the smart home do it!

Smart Home: Life in the networked home

A smart home is more than just a place to live – it is an intelligent and networked home that makes daily life easier. But what makes a smart apartment or house today and in the future? What role do sensor technology, software solutions, artificial intelligence (AI) and 5G play for smart home applications? We reveal it – in a nutshell.

What is a smart home?

The term smart home refers to the intelligent networking of different components or devices within a home that can be centrally controlled and monitored. A smart home – also called smart living, connected home, home automation, eHome or ambient assisted living – integrates different automation processes for networking the installed technical devices.

What makes a smart home?

Smart devices: compatibility plays the decisive role here. A uniform radio standard (e.g. WLAN, Bluetooth or ZigBee) allows devices to communicate with and among each other. In this way, automatic processes become possible.
 
Smart control: A central control of various devices and solutions in a house, is the basic requirement for a smart home. If the devices are compatible or even from one manufacturer, the control center can be, for example, a single app or even a voice assistant. Devices from different manufacturers or with different wireless standards mostly require multiple apps or control units on different end devices.

Smart automation:In a smart home, a wide variety of devices interact with or among each other. Commands from the occupants of the house or from sensors installed in the house reach the central control element. This end device, also known as a hub, bridge, base station, gateway or control center, subsequently triggers one or more actions with the help of actuators.

Example of an interaction of smart devices, smart control and smart automation

A smoke detector notices a fire and informs the control center. This follows a set routine. The fire department is informed by the system, the house alarm is activated and the owner:inside of the house receives a notification on their smartphone. The lighting of the defined escape routes is activated, any open windows and doors are automatically closed, and a possible lock on the front door is released to allow rescue workers access to the house or the occupants to escape. These processes run in parallel, fully automatically and within seconds.

Technologies and application areas in the smart home

a) Lighting systems: Intelligent lighting systems are one of the most basic smart home technologies. They allow remote control of lighting and adjustment of color and brightness. Sensors such as motion detectors can automatically turn lights on and off to save energy.

b) Heating and climate control: Smart thermostats and sensors allow residents to monitor and control the temperature in their homes. The system learns residents’ preferences and adjusts the heating or air conditioning accordingly to maximize comfort and optimize energy consumption.

c) Security systems:Smart security systems incorporate various solutions such as surveillance cameras, motion sensors, door and window sensors, and smart alarms. These systems allow residents to monitor their homes remotely and receive notifications when needed.

d) Home appliances: Smart home appliances such as refrigerators, washing machines, and robotic vacuum cleaners offer enhanced functionality and allow for remote control and automation of household processes.

Sensors and software solutions in the smart home

a) Motion sensors: Motion sensors detect movement in the home and enable the smart home system to detect activity and respond accordingly. They play an important role in automatically controlling lighting, security and energy saving measures.

b) Environmental sensors: these sensors measure parameters such as temperature, humidity and air quality. They help control heating, ventilation, and air conditioning, as well as monitor indoor climate for healthier and more comfortable living.

c) Voice Control: Voice control technologies such as Amazon Alexa, Google Assistant, or Apple Siri allow residents to control their smart home devices with simple voice commands. Voice assistants use advanced AI algorithms to recognize speech and implement commands.

The Artificial Intelligence Revolution in the Smart Home

AI plays a critical role in the advancement of smart homes. Through machine learning and data analytics, smart home systems can recognize the habits and preferences of residents and automatically take appropriate actions. For example, the system can adjust lighting and temperature according to preferences and the daily routine. Areas of the home that are not or temporarily hardly used, can be shut down during appropriate quiet periods to save costs and reduce the burden on the environment.

In addition, the AI continuously learns and adapts to the needs and habits of individual residents. As more data is collected and analyzed, the system will be better able to offer personalized recommendations and automation features. On this basis, resources such as electricity, heat and water can be optimally used. 

The importance of 5G for smart-home applications

The introduction of 5G or, in perspective, 6G networks will have a huge impact on smart-home applications. The high data rates and low latency of these technologies will enable seamless and reliable connectivity between smart-home devices and comprehensive access to home functions, even from long distances and in real time.

5G will also improve the scalability and flexibility of smart homes. As more and more devices are connected, 5G will enable reliable connectivity for a large number of devices without causing bottlenecks.

Outlook for future smart home innovations

a) Smart energy management:Future smart home systems will be even better able to optimize energy consumption and utilize renewable energy sources. Smart energy management systems will monitor power consumption and automatically turn on devices when energy costs are low or renewable energy is available.

b) Health and wellness applications: Smart home technologies will be increasingly integrated into the health and wellness sector. For example, sensors could monitor vital signs and send notifications when deviations are detected. Integration of fitness devices and apps will also increase to improve occupant wellness.

c) Enhanced security solutions:Smart home security will continue to improve by integrating advanced technologies such as facial recognition and biometric authentication. Integration of smart home security systems with external service providers such as police or security companies will also increase.

d) Augmented reality (AR) integration:AR technologies can help smart home users get visual information about their devices and systems. For example, AR glasses or smartphone apps can allow residents to view troubleshooting information, instructions or interactive user guides.

Conclusion

The smart home is an ever-evolving technology field with endless possibilities. Through the use of smart devices, sensors, software solutions, AI and 5G, smart control and automation, the apartment or house takes over recurring or annoying tasks, support in everyday life and manages itself in the absence of residents. Yet we are just at the beginning of this trend. Smart homes are becoming smarter, more efficient, more environmentally conscious and safer every year. Future innovations will further revolutionize connected living and provide residents with an even more comfortable living experience tailored to their needs.
