PowerCalc brings energy monitoring to devices that normally don’t support it.
- Lights, fans, media devices, and more
- No extra hardware needed
- Works seamlessly inside Home Assistant
Instead of measuring power directly, PowerCalc accurately estimates consumption using smart models based on real measurements.
- 💰 Save money - no need to buy smart plugs for every device
- 🔍 Full visibility - track energy usage across your entire home
- ⚡ Accurate estimates - based on real device measurements
- 🔌 Works out of the box - huge built-in profile library

PowerCalc creates virtual power sensors in Home Assistant.
For example:
- 💡 Lights → power based on brightness, color, temperature
- 🌀 Fans → power based on speed
- 📺 Other devices → configurable strategies or measured profiles
You get realistic energy data — without physically measuring every device.
PowerCalc is powered by a growing community:
- Contribute new device profiles
- Share measurements
- Improve accuracy for everyone
