This Raspberry Pi monitors your energy consumption
Keeping an eye on your home’s energy use has many benefits for the planet and your wallet, and it Raspberry pie project makes it possible. With this Pi-based monitoring system, created by manufacturer Mark Bryan Milligan, you can get an idea of what to expect when your electric bill rolls and troubleshoot individual circuit breakers in the event of a power outage with precision.
The system uses the Raspberry Pi 3 A+, a smaller version of the 3 B+ that omits Ethernet, equipped with custom HATs connected directly to Milligan’s circuit breakers. It can not only track the energy consumption in the house, but also monitor the data of a few solar panels.
The HATs were designed by Milligan in EasyEDA and manufactured by an online PCB manufacturing company. Each HAT has 16 TRS (Tip, Ring Sleeve) outlets that connect to $4 current transformers to read current information for the individual circuit breakers in each box. The case shell was designed by Milligan and 3D printed using a Monoprice Select Mini 3D printer.
The system is designed to collect data from the Pis into a server which transmits information in real time to an Android application. The app includes general energy consumption details and detailed datasets via graphs and more with a personalized user interface.
If you want to tackle this project on your own, a word of caution before proceeding. Mains voltage is deadly. If you have never worked with AC power before, seek advice from those qualified to do so and ensure your work is professionally checked and up to code before applying power. Milligan’s project uses clamp sensors on the power lines, it’s the safest approach, but proceed with caution.
