The existing electricity billing method used by electricity boards is opaque, making it difficult for the average person to understand his or her consumption. Furthermore, the invoices given by the boards provide no indication of a person's daily consumption. This research work has presented a warning system to address this issue and give a way to restrict MDI. The proposed model is a tap-and-click generation, and users expect to have everything readily available. When the load consumption exceeds the chosen threshold value, this alerting system will sound an alarm. The most essential aspect of the system is the residential users, and this alerting system will be more focused. This real-time monitoring enables us to make the most of IoT and, in the end, pave the way for smart cities.
