Modern technologies are used to secure the increasing human needs with the developments of the times as well as the provision of services, and it is considered necessary to remotely control the surrounding devices, especially those that depend on electrical energy for their work, in order to reduce energy consumption and manage and maintain devices. In current study, a system was designed that measures and monitors the energy and can control the devices remotely, as well as the possibility of making a decision to turn off the devices. The system is built by using an ESP-32S Node MCU and a PZEM-004T-100A sensor, and the control and connection to cloud computing is done by the Blynk server. The system connects by Bluetooth technology to the smartphone device through a program running on the Android system Serial Bluetooth Terminal to facilitate the Initializing the system, securing the system connection, and determining the highest value of the current to be consumed, in addition to the presence of a TFT color screen that works with several interfaces, including displaying the reading of electrical measurements, displaying system configuration information, displaying network connection, and displaying the highest value of the specified current. This proposed system is designed in a way that facilitates the process of monitoring and controlling the electric power of homes and making a decision when the threshold limit for the current specified by the user is reached. Where the system provides the house with two paths for the passage of the electric current, the first line connects the electrical devices directly in the system and one of the characteristics of the direct line is that it works to provide the devices with electrical energy and monitor the amount of energy consumed without controlling it remotely. As for the second line, high-capacity electrical devices are indirectly connected to the system, i.e., through a relay. One of the characteristics of the indirect line is to supply electrical energy to the devices. The indirect line can be monitored, controlled, and controlled remotely through the Blynk server.
