A lecture for those who want to live in a home that adapts to the rhythm of the day. The lecturer will explain how smart home systems work, when they truly save resources and effort, and when they turn into a meaningless expensive toy. Lecture attendees will look at an apartment through the eyes of both an engineer and a resident. They will learn how lighting, climate, multimedia, and security are interconnected in a smart home, and what happens when the 'morning' or 'nobody at home' scenario is activated. After all, the purpose of a smart home is to help solve real tasks: a comfortable morning wake-up, a child's peaceful sleep, monitoring the front door, and saving electricity and heat. The lecturer will explain the difference between a well-thought-out automation system and a chaotic collection of light bulbs and speakers bought on sale. Which functions are better to implement during the renovation stage, and which can be integrated into an existing interior? And where are the reasonable boundaries of automation so that the home does not turn into a technical quest with endless button management and notifications? In the end, questions of security, service, and budget will be addressed. The lecturer will discuss hidden costs, equipment reliability, and the importance of keeping the system understandable for all family members, including children and elderly relatives.
