"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.
It already knows your fridge
All that per-channel, high-frequency data feeds EnergyMe Intelligence, our load-recognition layer. It doesn't just measure a circuit, it names what's on it, with no extra sensors on the appliance.
Our fridge model is already running: it picks the compressor out from its sharp inrush peak and the steady, repeating cycle, exactly the pattern below.
