<![CDATA[Most household appliances use electricity as their energy. The need for electricity from year to year is getting bigger. Measurement of electrical power usage is usually done using simple measuring instruments and recording is still manual so that the data obtained cannot be done all the time and the results take too long to obtain. The appropriate technology for this problem is the Internet of Things (IoT) based electrical power monitoring system technology. capable of providing accurate and real-time results. The methods carried out are arranged in several stages, starting from data collection, design, configuration, implementation. The tools used in this research will use NodeMCU as the microcontroller, ACS712 current sensor as the electric current sensor, Virtual Private Server (VPS) as the web server. The results of this study are an electrical power monitoring system that makes it easier to monitor electrical power at home. The accuracy of power measurement by the system is 92.87%. Based on the error value, the electricity consumption monitoring system is good enough to be implemented at home.]]>
