Abstract: Manual home energy meter reading and billing had caused inconvenience to the utility companies due to lack of manpower to read the energy meter at each household especially in remote areas, which explains the increasing number of smart meter reader in the current market. Most of the smart meters in the market do not offer safety of privacy of consumers’ personal information since the data of electricity usage is being transferred digitally to the utility companies for more accurate bill calculation. Plus, the smart meter system comes with its own device for monitoring and control which makes the whole system expensive. In this paper, a private ESP8266 Wi-Fi moduleArduino compatible device that is capable of measuring energy consumption and calculating the bill according to the Malaysia electricity tariff is proposed. Current is measured using ACS712 current sensor that operates based on generation of magnetic field as a result of current flows in copper conduction path being converted into a proportional voltage. The proposed system allows real-time energy consumption with bill monitoring and On-Off control of the specific electrical appliance from a smartphone via a user-friendly graphic user interface of Blynk. Results shows that energy meter device developed, named Energy Sense, is able to measure current with average of 93.58 % accuracy from an air conditioner and 98.14 % accuracy from a water heater. The Blynk app is able to receive and show all the data transmitted from Energy Sense, particularly the energy bill and On-Off condition of the electrical appliance connected to Energy Sense at the present time, with 2 seconds delay in receiving the signal transmitted. Energy Sense is proved to be suitable in providing accurate energy measurement. Plus, long distance energy monitoring and On-Off control of electrical appliances connected to Energy Sense are successfully achieved.
