In today's and in the future technology trend there is a lot of interest in the development of smart devices that can be compatible with the IoT system. Internet of Things (IoT) based smart grid present a reliable, quality, secure and cost effective power supply automation of electrical power systems processes. Advancement of information acquisition, storage, processing, transmission, and sensor technologies have efficient systems for monitoring, evaluating by analysis, and perform efficient control of the electrical consumptions. In this paper, we propose smart meter data, to analyze and monitor the elderly people normal or abnormal behavior. The system performance is for real-time monitoring by automatically logging results and helping the patients always monitoring by their caregivers
