IoT Based Electricity Energy Meter with Dashboard 

EFY tested DIY

Track your electricity usage effortlessly with our non-invasive IoT energy meter. Real-time monitoring, easy setup, and safe for all electrical setups.

Energy meters in homes monitor electricity usage, enabling the government and electricity providers to bill us accurately. However, most traditional meters require manual reading, and both consumers and industries often need a smarter solution that provides real-time updates on energy usage and billing.

Current smart meters are typically invasive, requiring complex wiring changes, which raises concerns about short circuits and makes many users reluctant to switch. Additionally, these smart meters tend to be expensive.

To address these issues, we have designed a non-invasive IoT Energy Meter with IoT dashboard capability. This smart meter can be attached to any device, home wiring, office, or factory setup without modifying the existing wiring system.

Our design utilizes the SCT 013 non-invasive current sensor. The device includes a built-in Wi-Fi module that provides real-time updates on electricity usage and billing.

IoT Energy Metering – Coding 

The device can be configured to either connect to your Wi-Fi network or act as its own network.

By default, the device is set to STA (Station) mode, meaning it acts as a server and network.

You can connect your laptop or phone to the device by connecting to the device’s Wi-Fi network.

Additionally, calibration can be done in the code if you notice discrepancies between the readings of the standard IoT meter and our designed IoT meter.

IoT Smart Energy Meter – Testing 

Now, search for the Wi-Fi network on your phone. You will see the IoT meter in the list. Connect to it, then open a browser and enter the IP address. You can now see the readings. The display shows the readings, and a real-time graph will also plot the current and real power consumption in real time.
