Almost a year and a half ago, I developed an Energy Meter project using the Blynk application. For that, I used the SCT-013 Current Sensor and the ZMPT101B Voltage Sensor. These sensors were pretty accurate in reading the current value, voltage value, as well as power, and total energy consumed. However, the Blynk application recently underwent an update, rendering it unusable for this project. As a result, I decided to rebuild the project using the newly updated Blynk 2.0 application.
In this project, we will build an IoT-based Smart Electricity Energy Meter using the ESP32 and the newly updated Blynk 2.0 application. By using the best current sensor SCT-013 and voltage sensor ZMPT101B, we can measure voltage, current, power, and total energy consumed in kWh. The readings will be sent to the Blynk 2.0 application and displayed on a dashboard accessible from any location. In case of power outages, the energy meter data will be stored in the ESP32’s EEPROM memory, thus ensuring that the readings are not lost and are continuous. Let's start our project to automate electricity consumption monitoring.

Adjust the contrast using the potentiometer at the back of the display. Or it could be the I2C address issues, the LCD display has 2 i2c address, please check and modify the i2c address in code.
