"Can you see your energy?"
Don't just see your energy.
Take it apart.
EnergyMe Home doesn't stop at a number on a screen. It splits your panel channel by channel and, soon, appliance by appliance, until you know exactly what every device is pulling.
One board. Sixteen circuits.
EnergyMe Home is a DIN-rail energy monitor that measures 16 channels from a single compact unit, each one individually calibrated to 1% accuracy. It runs local-first, speaks native Home Assistant, and it is fully open source, hardware and firmware. Star it, fork it, tear it apart on GitHub.
What's on the stand
Where we started
A row of old PCBs, from the first oversized prototypes to today's tight, optimized layout. Same idea, a lot fewer square centimeters. The honest version of "we figured it out as we went."
The living panel
A real electrical panel wired with one EnergyMe Home and a handful of loads: a 200 W incandescent bulb, 3 to 5 W LED lamps, a 1600 W hairdryer, and a few wall sockets for chargers and small devices. Switch anything on and the monitor beside it reacts instantly.
The full picture
The second monitor shows the EnergyMe portal: the same data as a dashboard, broken down per channel, with history and trends. Where raw watts become something you actually read.
Teaching it to name what it sees
Because EnergyMe already splits the panel across many channels, samples at high frequency, and keeps the data clean and dense, we can go one step further: NILM, non-intrusive load monitoring. Instead of just measuring a circuit, the system learns to recognize the individual appliances on it, clustering loads by their electrical fingerprint.
Take a home fridge. Its signature is unmistakable: a sharp compressor inrush peak at every start, followed by a steady running plateau, repeating on a predictable cycle. Give an algorithm enough of those, and it can pick the fridge out of the noise on its own.
