In this paper, we present and discussed Internet of Things (IoT) based smart grid (SG) using smart meter (SM) for energy management techniques on Field Programmable Gate Arrays (FPGA). The SG allows for reliable communication and an efficient energy management system. IoT-based SG technology can manage and monitor remotely using Home Area Networks (HANs) for home energy management. HAN is equipped with SM to collect a huge amount of data from appliances to report their energy consumption. Home Energy Management’s (HEM’s) have the advantage of offering real-time energy usage to the consumer by limiting the power requirement to the SG. The paper addresses HAN system devices using ZigBee makes wireless communication effective for monitoring consumer's daily routine and by alerting security alarms with lower cost. The ZigBee network in connection with the microcontroller and interfaced with FPGA on HAN advanced the existing remote energy management system and the relatability and confidentiality of the SGs on the home energy management system.
