ESP32 Home Energy Dashboard Kit with ESP32 + LED
ESP32 Home Energy Dashboard Kit – Build a Grafana-Style Dashboard with PZEM-004T
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your home’s power distribution into a live data dashboard. You’ll mount three PZEM-004T nodes on separate circuits—mains input, solar inverter output, and battery backup—and have a central ESP32 serve a clean, real-time web interface. Monitor voltage, current, power factor, and energy consumption from any device on your network.
What You'll Build
You’ll build a complete three-point energy monitoring system. Each PZEM-004T module reads AC parameters over Modbus, sends them to an ESP32 node, and forwards data via Wi-Fi to a central ESP32 server. The server hosts a web dashboard with time-series graphs, gauges, and cumulative energy tracking—styled like a professional Grafana interface.
What You'll Learn
- Implementing Modbus RTU communication between PZEM-004T and ESP32
- Setting up a multi-node wireless sensor network using ESP-NOW or MQTT
- Building a responsive web dashboard with live charts (Chart.js)
- PCB assembly, buck converter power management, and DIN-rail enclosure design

Who This Kit Is For
Engineered for final-year B.Tech ECE/EEE students working on IoT energy monitoring capstone projects, Smart India Hackathon teams tackling smart grid challenges, and serious makers aiming to deploy a real home energy dashboard. Also ideal for faculty at IIT, NIT, VIT, and BITS Pilani guiding student projects.
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 on the box to start a chat with the AI companion, which understands this project’s wiring and code. You can also message us on WhatsApp for human help if needed.
Do I need prior experience with Modbus or web servers?
Basic Arduino/ESP32 programming knowledge is assumed, but our AI companion walks you through Modbus configuration, MQTT setup, and dashboard creation step-by-step—no prior web dev experience required.
Can I expand this kit to monitor more than three circuits?
The kit includes hardware for three sensing nodes. With additional PZEM-004T modules and ESP32 boards (sold separately), you can scale to more circuits using the same multi-node architecture.
Does the dashboard work on mobile phones?
Yes, the web dashboard is responsive and accessible from any device on the same Wi-Fi network. You can bookmark it on your phone’s home screen for quick, app-like access.
Three PZEM nodes on different circuits post to ESP32 which serves a Grafana-style energy dashboard.
