𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
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.

let's assume the wifi is faulty but there is power, does it have local (Offline Storage) that can be used during this time, so that when the wifi is back on it just syncs up? or does it just resume from where it lost connection?

For everyone whos checking out this project, be aware of the following: 1.The code used in the linked webpage is masking APPARENT POWER into REAL POWER and thats completely wrong. 2. Whats worse is that the energy calculation in the code takes apparent power as real power sooo guess what? the energy calculation is also wrong. 3. The ZMPT module introduces a phase shift in the voltage signal. This is because on the secondary side the signal is fed into an amplifier. This doesnt affect RMS voltage readings at all but it completely screws up the REAL POWER calculation. Im not saying this is a bad project at all, it works pretty well to get VRMS,IRMS and Apparent Power readings however forget about calculating real power, power factor and energy because as I said earlier, this is screwed up by the ZMPT module itself.. You may try to correct that phase shift by software but I cant guarantee you will get decent accuracy in the readings. If you want to calculate real power then you should use a crude step-down transformer.

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.
