I’m excited to share another DIY project: an Energy Monitor that I built to track and analyze my home’s electrical consumption. This comprehensive system measures grid consumption metrics, displays real-time data on an OLED screen, and stores everything in an InfluxDB database for long-term analysis.

Energy Monitor Module

The project was born from the principle that “You can’t improve what you don’t measure.” I wanted to observe and store my energy consumption data to eventually optimize it, and well… it also looked like a really cool DIY project (which it turned out to be!).

The module was designed to fit any European-standard distribution board with the same form factor as a circuit breaker, featuring a 90mm (5-module) width. It doesn’t collect data directly but rather fetches metrics from Lechacal’s RPICT module and Enedis Linky electric meter (France’s national power provider).

This project demonstrates how modern DIY electronics can create professional-grade energy monitoring solutions. The combination of Raspberry Pi, custom Rust application, and smart data visualization showcases the full spectrum of skills needed for comprehensive IoT projects. The Energy Monitor is now successfully tracking my electrical consumption and providing valuable insights through data visualization and analysis.
