Smart Grid Demand Response Kit: ESP32 Meters + Pi 5 Aggregator
Smart Grid Demand Response Simulation Kit with 3 ESP32 Smart Meters & Pi 5 Aggregator
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In this lab kit, you create a scaled-down smart grid: three ESP32-based nodes act as smart meters, continuously measuring current draw (simulating household loads) and transmitting data wirelessly to a central Raspberry Pi 5 aggregator. The aggregator analyzes real-time consumption and issues demand response signals-just like a utility managing peak load. This is a hands-on way to explore IoT, energy management, and the future of India's power infrastructure.
What You'll Build
A fully functional demand response simulation. Three wireless sensor nodes, each built around an ESP32 and an ACS712 current sensor, report load data to the Pi 5 aggregator over MQTT. The aggregator logs the data, displays trends, and can trigger load-shedding commands when total consumption crosses a preset threshold. The system uses an M.2 NVMe SSD via the Pi 5 M.2 HAT+ for fast data logging. By the end, you'll have a working prototype of a smart grid edge controller.
What You'll Learn
- Design and program ESP32 nodes for wireless current sensing and MQTT communication.
- Configure a Raspberry Pi 5 with M.2 storage and set up an MQTT broker for multi-node data aggregation.
- Implement demand response logic using real-time power measurement and threshold-based load control.
- Visualize grid data using Python dashboards and understand smart meter data structures.

Who This Kit Is For
This kit is designed for engineering and polytechnic students building lab projects in smart grid, IoT, or embedded systems. It fits perfectly into B.Tech ECE and EEE curricula at IITs, NITs, VIT, BITS, and state universities, as well as CBSE Class 11-12 students exploring AI and IoT. Whether you're preparing for the Smart India Hackathon, an ATL Tinkering Lab showcase, or a final-year project, this kit provides a complete, guided experience.
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?
Our AI companion, trained on this exact project, provides step-by-step guidance. You can also reach us on WhatsApp for quick answers.
What programming languages are used?
The ESP32 nodes can be programmed in Arduino C/C++, and the Pi 5 aggregator uses Python with MQTT libraries. All code examples are included.
Do the ACS712 sensors need calibration?
Yes, basic calibration is required; we provide a clear procedure and the AI companion walks you through it.
Can I expand this to more than three nodes?
Absolutely - the architecture supports adding any number of ESP32 meters as long as each has a unique MQTT client ID. The Pi 5 aggregator can handle dozens.
Multiple ESP32 nodes simulate smart meters reporting consumption to a Pi 5 aggregator - demand response simulation.
