Energy consumption in residential households is very important to consumers. The rise in electricity prices have deemed to consumers the need to conserve energy, with less to no information on their energy consumption patterns. A step to towards energy conservation is a real time energy monitoring system which provides feedback to the consumers, thus the consumer will be able to identify the opportunities to adjust and identify how to conserve energy. This paper presents a real time energy monitoring system that is cost-effective and reliable, it can be used to analyze and evaluate the output voltage or generated energy from a household appliance. A hardware device is used to gather energy data passed and stored to a database through cloud-based RESTful API resources. These resources are then used by the mobile web application for displaying real-time and historical energy readings. The developed monitoring system have an accuracy rate of 94% in getting the correct energy consumption through testing. The results of user's feedback during testing provides insights to supplementary features which shows the usefulness of the energy monitoring system.
