## Heating Curve Description
Is your heating curve set correctly? Stop guessing – see the answer instantly.

HeatCurve visualizes the relationship between outdoor and indoor temperature so you can see if your heat pump is delivering the right heat. Adjust slope and offset with confidence instead of trial and error.

SIMPLER THAN HOME ASSISTANT
No complex configuration. No Grafana. Just a clear graph showing whether your settings are working.

TWO WAYS TO MEASURE
- Automatically via Netatmo sensors – connect your existing equipment
- Manually – enter readings whenever it suits you

HOW IT WORKS
1. Collect temperature data (indoor + outdoor) across different outdoor temperatures
2. See the trend in the graph
3. Save your heating curve settings (slope, offset)
4. Compare different periods and see what works best

PERFECT FOR
- Homeowners with ground source, air-to-water, or other heat pumps
- Anyone who wants to save energy without sacrificing comfort
- Everyone wondering "why is it always too warm/cold?"

All data is stored locally on your device. No subscription, no hidden costs.
