Development of wi-fi input/output modules for home automation systems

Diplomska naloga prikazuje postopek razvoja in izdelave vhodno/izhodnih modulov ter njihovo vključitev v sistem hišne avtomatizacije Domoticz, z uporabo brezžičnega omrežja Wi- Fi in protokola MQTT. Hišna avtomatizacija temelji na modelu z osrednjo enoto in vhodno/izhodnimi moduli. Osrednja enota z naloženim sistemom Domoticz pošilja sporočila modulom, na katere se le-ti ustrezno odzovejo. Moduli lahko delujejo kot aktuatorji ali senzorji. Domoticz vsebuje uporabniški vmesnik, s katerim je mogoč oddaljen dostop do hišne avtomatizacije in s tem nadzor uporabnika nad celotnim sistemom. Z uporabljenim protokolom MQTT je zagotovljen nemoten in zanesljiv prenos podatkov med posameznimi enotami hišne avtomatizacije.Diploma work shows development and production of input/output modules and their implementation into Domoticz home automation system. This is done by using Wi-Fi communication with help of MQTT protocol. This home automation is based on a model in which you have the main unit, that has installed Domoticz and is sending messages to the connected modules, that generate appropriate response according to the message. Modules can act as sensors or actuators. Domoticz has built-in user interface which can be remotely accessed. By using MQTT protocol the data transfer is safe and reliable between the main unit and modules
