Communication of IoT devices in a smart home

Danas postoji mnogo uređaja Internet stvari raznih proizvođača i svaki ima svoj način komunikacije. Prilikom kupnje uređaja potrebno je obratiti pažnju na kompatibilnost pa nastaje želja za spajanjem svih protokola u jedinstveni sustav. Novi standard otvorenog kȏda Matter nastoji riješiti taj problem, no preostaje vidjeti hoće li riješiti taj problem ili je riječ o samo još jednom standardu. Ovaj rad posvećen je komunikaciji IoT-uređaja u pametnom domu, sažeto se daje usporedba postojećih protokola i opisuje se standard Matter. Analizirane su mogućnosti i vrste poruka koje se izmjenjuju prilikom komunikacije, a implementacija komunikacijskog sustava izvedena je pomoću Raspberry Pija.Today, there are many Internet of Things devices from various manufacturers and each has its own way of communicating. When buying a device, it is necessary to pay attention to compatibility, so there is a desire to combine all protocols into a single system. The new open-source Matter standard aims to solve this problem, but it remains to be seen if it will solve this problem or if it is just another standard. This paper is devoted to the communication of IoT devices in a smart home, a comparison of existing protocols is briefly given and the Matter standard is described. The possibilities and types of messages that are exchanged during communication were analyzed, and the implementation of the communication system was carried out using Raspberry Pi
