Recently, Smart Infrastructure is an emerging technology to save power and improvisation in the standard of living. This invention relates to artificial intelligence based voice control over a large number of electrical appliances with no limitation of location. In addition to that, the control can be achieved efficiently over long distances. This invention is aimed to provide lockdown mode for security over malicious attacks. The main objective of the present invention is to predict the life of the electrical appliances by analyzing the power pattern. The number of Raspberry Pi, Arduino, and other devices should be installed in such a way that the resultant system is intelligent, safe, user-friendly, ready to install anywhere, accurate and efficient with optimum control over the wide range of electrical appliances irrespective of their numbers and incorporates condition monitoring feature.
