Abstract

Glede na to da trenutni sistem naˇse hiˇse ni ravno zastarel, hkrati pa ni tako napreden, da bi omogoˇcal funkcije, kot sta zbiranje informacij na enem mestu in spreminjanje parametrov, sem se odloˇcil, da sistem nadgradim s tehnologijo, ki bo to omogoˇcala. Srce sistema je centralna enota Raspberry Pi, na kateri teˇce odprtokodna programska oprema openHAB 3. Na to centralno enoto se prek protokola MQTT poˇsiljajo vsi podatki z vseh merilnih mest. Centralna enota se odloˇca na podlagi vhodov in aktuatorjem poˇsilja navodila o tem, v katero stanje se morajo postaviti. Podatki se prikazujejo na rezistivnem zaslonu na dotik Nextion, ki prek serijske komunikacije z modulom ESP8266 pridobiva in poˇsilja ukaze za prikaz oziroma spremembo. Vse te funkcije se lahko spremljajo in upravljajo tudi z mobilnim telefonom. Hiˇsna avtomatizacija bo seveda imela najveˇcji vpliv na centralno ogrevanje, saj bo mogoˇce spremljati razliˇcne temperature na razliˇcnih delih sistema in glede nanje ukrepati, da pridobimo ˇcim viˇsjo uˇcinkovitost delovanja. Ker je okrog centralne peˇci veliko razliˇcnih aktuatorjev, ki za delovanje potrebujejo veˇc energije, kot jo lahko odda ESP32, se je izdelalo tiskano vezje, da je sistem ˇcim bolj kompaktna ter omogoˇca ˇcim laˇzji priklop na izhodne in vhodne naprave. Vse kljuˇcne operacije so narejene tako, da v primeru okvare mikrokrmilnika ali nedelujoˇce komunikacije lahko prekrmilimo na roˇcni naˇcin

Secondary abstract:	Since our house system is not outdated but at the same time not exactly advanced enough to offer functions such as gathering information in one place and changing parameters, I decided to upgrade the existing system with a technology that would support these functions. The core of the system is Raspberry Pi with the openHAB 3open source server. The central unit receives data from all measuring sites through the MQTT protocol. The server also makes decisions based on the inputs and sends orders to actuators about the state they should go to. The data are visualised on a resistive touch screen Nextion, receiving and sending messages for indication or change of parameters over serial communication with ESP8266. All these functions can also be monitored and controlled with a smartphone. This house automation will have the biggest impact on the central heating system, as it will enable changing the temperature on different parts of the system and based on that making a decision to achieve higher efficiency. Around the central heating system, there are many actuators requiring a lot more energy that the ESP32 can provide; therefore, I decided to make a printed circuit board to ensure the system would be as compact as possible and allow easy connection to all actuators and sensors. The entire system is designed so as to ensure that, in case of an equipment or program failure, it is still possible to run essential parts manually
