A Firebase-Based Smart Home Automation System Using IoT

The rapid development of IoT and its associated hardware and software systems has facilitated the design, development, and implementation of smart home automation systems. But the existing systems are either operated using physical electrical/mechanical switches only or operated using mobile app only but not both or interchangeably. It means once a device is switch-on using a physical switch it cannot be switch-off using the mobile app developed for that device. This research paper is going to solve this limitation. This paper presents a smart home automation system using NodeMCU (an open source IoT platform) and Firebase (a powerful cloud service). This presents a mobile app-based home appliance control system which provide the flexibility to control even a physical switch operated appliances remotely. The proposed system is physically developed, implemented, and tested in real-time environment and proved successful.
