Application corresponds to a software module used as additional logic to home automation system. Each application requires only necessary system resources based on its purpose and demands, hence division of system functionalities to separate modules was necessary. This encapsulation resulted in emergence of so called system packages – an interface through which applications interact with system resources like database, cloud connection or smart devices control. On the other hand, by demands regarding user management and customization of system, basic home automation features are partitioned into removable modules. These ideas, along with requirements of being lightweight, removable, accessible from any existing personal device and developed with standard technologies, make the concept of applications for home automation system. Application module consists of three major parts called back-end, front-end and manifest file, packed in one archive that can be installed or removed from the system. Applications are designed in client/server software architecture, where server part is within gateway device, and client part rests on controller device. Each application has connection to its dedicated back-end; however, the existence of single, transparent, supervisor software must be satisfied for the sake of applications security, resource management.


With Admin application, we showed just some of solution capabilities, which already overcame constraints of existing home automation systems. Configuration and control of home automation system through developed extension is possible independent from OS platform of controller device, and was implemented with widely accepted technologies. Using only basic Web developing techniques it is possible to develop an extension for home automation system. Considering this, we give opportunity to developers of all experience levels to anticipate in its expansion. Users can enjoy these applications on all devices that supports Web browser, which is also widely supported. These were the main limitations of systems that support some sort of user manageable extensions. Future work will cover designing of advanced applications, such as: location based device control, scenarios management and power consumption insight, as well as realization of template application for other developers, which will reduce necessary time for development and ensure quality of new applications.

4. ZigBee Based Home Automation:

The ZigBee wireless communication technology can be applied for home automation. The system uses PIC microcontroller and voice recognition for this purpose. The voice commands are taken from a mike. They are compared with a voice store and processed. The PIC microcontroller then transmits the commands through ZigBee to the receiver. The receiver unit has another PIC microcontroller that can process the command. It uses relays to control the respective appliances. This system has the drawback that ZigBee is a low range communication medium. So remote access is hindered from faraway locations. Also, the voice recognition module could become unwieldy. This system has the added feature of integrating a smoke detector to the system. When smoke is sensed, it sends a message to the user’s built-in mobile number.
