Build a Whole Home Energy Monitor with ESP8266 – Live kWh Charts via Local Network

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Wondering why your electricity bill spikes every month? With this kit, you’ll build a WiFi-connected energy monitor that clamps onto three appliance lines and logs real-time current, power, and cumulative kWh to an SD card – while simultaneously serving a live energy chart on your phone or laptop over your local network.

What You'll Build

You’ll assemble a compact circuit on a breadboard with three ACS712 current sensors, an ESP8266, a real-time clock, and an OLED display. Once configured, it logs energy usage every second, stores data to a microSD card for long-term analysis, and broadcasts a responsive web dashboard showing real-time wattage and daily kWh totals for each monitored circuit – accessible from any device on your WiFi.

What You'll Learn

• Calibrating non-invasive current sensors for accurate AC power measurement
• Programming the ESP8266 to read analog sensors and serve a real-time web interface
• Logging time-stamped sensor data to an SD card with file management
• Visualizing energy consumption data for energy audit and cost-saving decisions

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11-12 students tackling IoT-based physics investigatory projects, B.Tech ECE/EEE mini-projects on energy management, Smart India Hackathon teams building consumption dashboards, and ATL Tinkering Lab mentors guiding real-world sensor applications. Equally suited for IIT, NIT, VIT, or BITS learners who want a hands-on introduction to non-invasive current sensing and data logging without soldering.

Built and Backed by Compoden
