Energy management system for the household appliances in terms of monitoring and control is described in this paper. Monitoring the energy consumption is the initial step to reduce it. The smart device is designed and developed that will monitor the load device parameters like voltage, current, power factor, power consumption and frequency. The load device is made to turn OFF/ ON based on the status of the device through the mobile application. To get the measured data and to control the load device an Android application has developed, which uses a mobile-enabled Bluetooth to communicate with the Bluetooth low energy module, which is interfaced to the host microcontroller. Bluetooth module is used as it works well for home automation applications. The proposed device has a simple design, low power consumption, cost-effective and easy to interact with the user.
