In today's society, there is a growing demand for smart home solutions that not only enhance convenience but also make a significant impact on affordability and widespread adoption. This paper describes the proposed design of a Node MCU-based Home Automation system with an integrated Wi-Fi module that enables internet-based remote control of home devices. The design utilizes a basic code template to connect with the Tasmota Web interface to configure the ESP module. The system is integrated with Alexa, offering various integration options such as routines, schedules and alarms. Furthermore, it adds a manual control feature for situations where there is no internet connection and an additional level of safety through emergency controls in the event of electronic failure. A comparison of energy usage with and without the use of the proposed system is also reported. A noticeable decrease in daily electricity consumption is observed on using the designed automation system. To ensure costeffectiveness, locally available components are utilized in the design. Consequently, it ensures that enhanced comfort, convenience, and control over one's living environment are available to a wider audience. [ABSTRACT FROM AUTHOR]

Reducing energy consumption in the household and commercial sectors is a major global concern. Our objective is to develop a low-cost automation solution that will help improve adoption and reduce energy consumption. Proposed system has functionality that will help typical Indian households reduce electricity consumption in areas of infrequent usage such as stairs, and parking areas where manual switching of the electricity is difficult. In our proposed model, a manual switching system is replaced with a low-cost and adaptable smart automated switching system. Our design is based on the Passive/Pyroelectric Infrared Rays (PIR) motion-sensing mechanism where motion is used as a trigger to turn on/off electrical appliances. Detailed comparative analysis of daily energy usage of traditional switching with intelligent switching showed reduced electricity consumption by 33 %. Lower cost of equipment will increase the adoption of automated systems, leading to a reduction in electricity consumption. Further, a drop in energy consumption means reduced energy costs and less burden on the grid which leads to a clean environment. [ABSTRACT FROM AUTHOR]
