## ⚡ Turn any device into an energy monitor, no smart plug required
**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.

## Why use PowerCalc?
- 💰 **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
- 🧠 **Advanced modeling** - brightness, color, fan speed, and more
---
## How it works
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.
