+- **Schedule Control**: Day/night temperature targets per weekday
+- **Summer Mode**: Automatic heating disable based on outdoor temperature
+- **Safety Monitoring**: Sensor sanity checks with automatic safe-state fallback
+- **Prometheus Metrics**: HTTP endpoint at port 9100
 
 ### Prometheus Metrics

+## Configuration
 
+All parameters configurable via `idf.py menuconfig`:
+- WiFi credentials and static IP
+- GPIO pin assignments
+- 1-Wire sensor addresses
+- Temperature thresholds and limits
+- Heating schedule (day/night per weekday)
+- Damping factors

+```bash
+idf.py set-target esp32
+idf.py menuconfig  # Configure settings
+idf.py build flash monitor
