In this modern generation, there is a lot of technological improvement in Smart Home Automation. Real-time data collection and transmission through sensing devices is possible in the rapidly expanding "Internet of Everything" network of interconnected objects. The most realistic solution seems to be the affiliation of semantic information with all these diverse data sets via resource management, empowering their reusing and the implementation of rationale processes meeting up as well as skills for several momentary home automation control apps for a development's building providers of sub-standard systems lacking in intelligence. To overcome these issues in this paper, CREM has been proposed. In this research, a novel Cost-efficient Resource Management has been proposed in Smart Home Automation. The presented CERM has been simulated using MATLAB.
