Abstract

Da bi pametna kuća bila "pametna" potrebna je određena
razina autonomije i "pametnog" upravljanja energijom.
Autonomija je izvedena PI regulatorom koji upravlja
grijanjem i hlađenjem prostorije. Također, PI regulator može
se smatrati i mjerom štednje energije zbog svoje povratne
veze odnosno zato što na svaku promjenu reagira postupno i
izbjegava nepotrebno korištenje maksimalne snage uređaja.

Za implementaciju korišteni su Home Assistant instaliran na
Raspberry Pi 4, 2 M5Stacka i 2 Croduina NOVA2. Uređaji su
podijeljeni na razine ovisno o ulozi: na najnižoj razini
nalaze se Croduini NOVA2 kao sučelja s fizičkim uređajima.
Na srednjoj razini nalaze se M5Stackovi koji nude grafičko
korisničko sučelje i mogućnost podešavanja parametara
pametne kuće (npr. ciljana temperatura zraka). Na najvišoj
razini nalazi se Home Asistant čija je uloga povezivanje
komponenata druge i treće razine, ali ima i mogućnost
nadjačavanja upravljanja koje nude M5Stackovi na svojoj
drugoj razini. Svi uređaji povezani su WiFi-jem u lokalnu
mrežu i komuniciraju protokolom MQTT.

Abstract (english)

In order to achive the "smartness" of a smart home, a
certain level of autonomy and "smart" energy management
are required. The autonomy is implemented using PI
regulation which is in control of heating and cooling a
room. Furthermore, PI regulator can also be interpreted as
a measure for saving energy as it reacts to each
temperature change gradually and tries to avoid
unneccessary usage of heating or cooling device power.

Home Assistant installed on a Raspberry Pi 4 paired with
two M5Stacks and two Croudino NOVA2s were used to
implement the system. The devices were divided into layers
based on their role in the whole system: the lowest layer
is represented by the Croudino NOVA2s which are the
systems interfaces with physical devices. The middle layer
is represented by two M5Stacks which offer a graphical
user interface that enables the user to set the smart home
parameters (e.g. target room temperature). The top layer
is represented by Home Assistant which is in charge of
enabling the lower two levels to communicate, but it also
has the ability to override the middle layers control. All
the mentioned devices are connected over Wi-Fi in a local
network and use MQTT protocol to communicate.
