This paper proposed and implement a microcontroller-based smart meter that utilizes the GSM as wireless communication with the utility server. The scheme aims to build a low-cost smart power meter that improves the electric grid and prevents electricity loss, making life more comfortable for the consumer and utility. Raspberry Pi3 server equipped with programmed systems in highly efficient and reliable languages (PHP and Python) and secure databases (MySQL) to set up an automatic metering and billing system.The proposed system provides exchange information between the consumer and the utility, where the consumer can access his data through a web page. Issuing a monthly bill and sending it to the consumer by e-mail and SMS as well as disconnecting the power source in case the consumer fails to pay his bill.
