ESP32 Smart Energy Prediction Kit - Monitor Appliance On/Off Status
ESP32 Smart Energy Prediction Kit - Monitor Appliance On/Off Status in Real Time
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a device that clips onto any appliance power cord, measures current without cutting wires, and uses a simple algorithm to predict if the appliance is running-then instantly notifies your dashboard via MQTT. This ESP32-based energy prediction node does exactly that, giving you an entry point into smart energy auditing and IoT automation. The kit includes everything from the precise ADS1115 ADC to the clear OLED display, so you focus on building and learning, not sourcing parts.
What You'll Build
You'll assemble a self-contained node that reads AC current through a non-invasive SCT-013 clamp sensor, converts it to a digital value using the high-resolution ADS1115, and displays live current and appliance state (ON/OFF) on a 0.96-inch OLED. The ESP32 runs a threshold classifier-if current exceeds a calibrated trip point, the appliance is considered ON-and publishes the state change over MQTT to any broker, making it ready for Home Assistant or Blynk dashboards.
What You'll Learn
- How to connect a non-invasive current sensor safely to an ESP32
- Analog-to-digital conversion with the ADS1115 for high-resolution current readings
- Implementing a threshold classifier to predict appliance on/off states
- Publishing sensor data and predictions to an MQTT broker for IoT dashboards

Who This Kit Is For
Whether you're a CBSE Class 12 student building a physics investigatory project on electrical energy monitoring, a B.Tech ECE learner prototyping for Smart India Hackathon, or a hobbyist exploring MQTT without wrestling with separate component compatibility, this kit is tailored for first-time IoT builders. ATL Tinkering Lab instructors appreciate the safe, non-invasive sensor and step-by-step guidance.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with the AI companion trained on this specific kit; it can debug wiring, code, or sensor calibration. WhatsApp and email help are also available for any edge cases.
Can this kit measure voltage as well?
No, it only measures AC current via the clamp sensor. To measure true power you would need a voltage reference, but the kit focuses on state classification using current alone-a simpler and safer first project.
Is it safe to clamp the SCT-013 onto a live wire?
Yes, the SCT-013 is completely non-invasive and insulated. As long as you do not touch exposed conductors and follow the guide, it's a very low-risk way to learn current sensing.
Can I use this with Home Assistant?
Absolutely-the MQTT messages from the node can be consumed by Home Assistant's MQTT integration, allowing you to create automations based on appliance states within minutes.
Current sensor data on ESP32 predicts appliance on/off state using threshold classifier - reports via MQTT.
