The proposed system is highly flexible as it uses Wi-Fi technology to interconnect between the controlled board & Wi-Fi module. This system uses 4-loads to control house appliances, and has user-friendly interface that allows user to easily control the Malay house appliances through the internet. The proposed system consists of NodeMCU (Node Microcontroller Unit) and powered by 5V Adaptor/Charger (Micro-type). The NodeMCU, is connected to a relay unit to operate electrical appliances over the internet. Meanwhile, the loads are controlled by relays. After the user sends commands over the internet, the NodeMCU processes the instructions to operate the loads accordingly, and displays the system status on a smartphone display. Thus, this system allows for efficient home automation over the internet. Keywords—IoT, NodeMCU, Home Automation, Wi-Fi Module, Smart Phone, Traditional Malay House, Vernacular House I. INTRODUCTION A home automation system allows end-user to control and manage their electric appliances remotely. By analysing different home automation systems over time, they have always sought to develop efficient, easy, and safe ways for home dwellers to access their homes remotely. As mentioned in [1], traditional Malay houses were built in response to the Malays' actual housing needs and inspirations. Thus, due to that, the house is a wonderful fit for their socioeconomic, cultural, and environmental needs. Regardless of changes in customer expectations, technology improvements, or the passage of time, the appearance of a home automation system has stayed unchanged. Traditional Malay houses now are majorly occupied by the second or third generation, thus there is need or higher demand for implementation of special technologies or facilities in the house. Many common home automation systems, such as Arduino and Raspberry Pi-based systems, rely on wired connections. These settings should not be a problem if the system was well-planned ahead of time and installed without compromising the building's architectural values during construction. The cost of implementation on the existing buildings can go very high. Comparatively, wireless systems for automatic systems, like Bluetooth, Wi-Fi and IOT based home automation systems has lower cost [2-4]. With the advancement and gradually declining cost of wireless technologies such as Wi-Fi and cloud networks, wireless systems are have become more feasible for use anywhere. Malay houses usually encompass three main constituents, which are physical, spatial and functional. As a consequence, a traditional Malay house is a place where Malays may rest, feel at ease, and be satisfied because the house's design symbolises their desired way of life [5]. Bluetooth and Wi-Fi provide wireless communication through radio signals. The most significant distinction between Bluetooth and Wi-Fi is that Bluetooth is used to link short-range devices for information sharing, however Wi-Fi enables high-speed web access or internet. Wi-Fi provides high information measure because the speed of web is a vital issue. Bluetooth has no full form meaning with regards to its name, while Wi-Fi stands for Wireless Fidelity. For connectivity, Bluetooth technology only requires a Bluetooth adapter on all devices, whereas Wi-Fi requires a wireless adapter on all devices as well as a wireless router. Bluetooth consumes low power while Wi-Fi consumes high power. Bluetooth is less secure than Wi-Fi in terms of security, but it is also less flexible because it only allows a limited number of users, whereas Wi-Fi supports a large number of users. The radio signal range of Bluetooth is ten meters and requires low bandwidth, whereas Wi-Fi has range of a hundred meters and requires high bandwidth [6-9]. With the development of various technologies today, they can be integrated to traditional Malay homes to support smart home functions such as the ability to monitor fresh air flow and air humidity; even to control electrical appliances in the home. Despite the addition of various technologies on the construction of traditional Malay houses, the design features of Malay houses will still be maintained. The existing elements and characteristics of traditional Malay houses need to retained without damaging the authentic values of traditional Malay house. The adaptation of the technologies into traditional Malay house is one of the methods to conserve the Malay house and keep people to continue living in it.
