Can you see your energy?
EnergyMe measures every circuit in your electrical panel, in real time, so you finally see where the energy goes. Open-source hardware and firmware, local-first data, native Home Assistant.
Switch something on. Watch it count.
Everything is off. Tap a circuit.
That was a simulation. The portal is real.
Open our live demo: a real house, every circuit, live. No account needed.
Three things to see, in this order
The panel demo
An EnergyMe Home on a DIN rail with real breakers and clamps. Switch a load on and the tablet next to it reacts at once.
→ flip the switchesThe data
The first screen runs the EnergyMe portal: every circuit on its own, history, costs, and a forecast of the day.
→ left screenWhat the data knows
The second screen shows what we recognise from the current alone: the fridge, the washing machine, an empty house.
→ right screenIt lives in your panel
One DIN-rail unit next to your breakers, one clamp per circuit. That is the whole installation.
EnergyMe Home
a clamp per circuit
16 circuits
Rendered from our own design files: the same 3D model is on energyme.net. Every board, every connector is the real one.
Every appliance leaves a trace
No sensor on the appliance. From the current on a circuit we pick out what is running, and learn each house from its own data.
Guess the appliance
Your turn to be the algorithm. Read the curve and pick.
Shops, restaurants, workshops
The same idea on a three-phase panel. Know what every machine costs, and what keeps running when the doors are closed.
What runs at night
Fridges, HVAC, forgotten machines: see the base load when nobody is there.
Opening hours from the meter
When a site really opens and closes, read from which circuits wake up.
Many sites, one view
For chains and franchises: every location on the same scale.
Build it, hack it, improve it
Schematics, PCB, firmware and the Home Assistant integration are all public. If you like taking things apart, you are in the right place.
