Pi 4 Home Energy Monitor with Grafana
Raspberry Pi 4 Home Energy Monitor with Grafana Dashboard – Track kWh & Electricity Costs
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Monitor your home's electricity usage in real time. Connect three ACS712 current sensors to your mains or appliance circuits, feed data to a Raspberry Pi 4 running Python, and visualise daily kWh and cost through a beautiful Grafana dashboard. This kit delivers the hardware and AI guidance to build a professional-grade energy monitoring system.
What You'll Build
A fully integrated energy monitoring station that reads current from up to three circuits simultaneously. The Pi logs measurements every second, stores them in InfluxDB, and Grafana renders live charts of power, daily kilowatt-hours, and estimated electricity expenses. You'll see exactly which appliances consume the most, and the system can be extended to track solar generation or smart plug data.
What You'll Learn
- Interfacing ACS712 analog current sensors with ADS1115 ADC and Raspberry Pi GPIO
- Writing Python data logging scripts with timestamped InfluxDB writes and error handling
- Configuring InfluxDB time-series database and designing multi-panel Grafana dashboards
- Calculating kWh and electricity cost from instantaneous current readings, voltage assumptions, and calibration factors

Who This Kit Is For
B.Tech ECE/EEE undergraduates building mini‑projects or Smart India Hackathon entries will find the real-time data pipeline a perfect fit. ATL Tinkering Lab mentors can use this to demonstrate IoT energy analytics. Students from IIT, NIT, VIT, or BITS looking to explore time-series databases and dashboard frameworks will get hands-on experience with industry tools like InfluxDB and Grafana.
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?
Just scan the QR code for the AI companion that knows every step of this energy monitor build, or reach us on WhatsApp for human backup within hours.
How do I calibrate the ACS712 sensors to get accurate kWh readings?
The AI companion walks you through a no-load calibration routine and the voltage assumption logic. It also helps adjust offsets in Python code so your daily kWh totals match your electricity bill within 5%.
Can I monitor more than three circuits with this kit?
The included ADS1115 has four channels, so you can add one more sensor (sold separately). The AI companion explains how to expand the Python script and dashboard panels for additional inputs.
What Grafana dashboard features are pre‑configured?
You get real-time current graphs, daily kWh accumulation, running cost estimates, and a simple input for your per‑unit tariff. The AI companion also guides you on adding alerts for high usage or appliance‑specific breakdowns.
Three ACS712 clamps on circuits feed Pi 4 Python logger. InfluxDB and Grafana show daily kWh and cost.
