In the documentation, I have listed the requirement for a 9V AC power supply. The project does have a requirement for AC input source voltage. “there’s no support for input voltage, so It can’t really distinguish reactive power nor calculate real power.” I can’t reply to atomd or tekkieneet directly – not sure why, but I wanted to correct their assumption on the capabilities of my project. Thank you Tom for doing most of the hard work for me. I purchased monitoring units from the UK which were thrown in the dirtbin as they could not do what this project does. You need something like this before solar installation to monitor for a while to be able to properly define the number of panels you need and the battery capacity that will be needed. It is invaluable when deciding to fit solar. It is intended to assist in finding problems where power is consumed and should not be. This tool is not intended for you to save a watt on your router or your kettle. It’s not the 15W for the pi (which in reality is more like 7 watts, it’s the fact that can diagnose a problem that consumes KW. So that’s the use for the project if you are not interested in solar power. If they are short spikes, then all is ok. This is usually water heating and means that something is wrong with the insulation of the water heater. If you are just looking at power consumption, the graph shows a periodic 4kW that turns on about twice an hour. Pinhead, I am not sure what country you are in – but it must be the North Pole.įor the rest of us, living south of the pole, it’s a useful project.
This is an old post, but I have to comment.

Home energy monitoring projects are certainly nothing new, but the incredible advances we’ve seen in the type of hardware and software available for DIY projects over the last decade has really pushed the state-of-the-art forward. He’s even offering hardware kits for anyone who’s more interested in experimenting with the software side of things than building the PCB. While has already done the community a great service by releasing the hardware and software under an open source license, he’s also produced some absolutely phenomenal documentation for the project that’s really a valuable resource for anyone who wants to roll their own monitoring system.
Data is pulled every 0.5 seconds from a MCP3008 ADC connected to up to five six current sensors to provide real-time utilization statistics, and visualized with Grafana so you can see all of the information at a glance. This project includes provides software and hardware to be used in conjunction with the Raspberry Pi to keep tabs on not just home energy consumption, but also production if your home has a solar array or other method of generating its own power. At a minimum one of these setups involves a microcontroller and some kind of clamp-on current sensor, but if you’re looking for resources to take things a bit farther, this Raspberry Pi energy monitoring system created by would be a great place to start. As the world has become more environmentally conscious, we’ve seen an uptick in projects that monitor or control home energy use.
