--- sidebar_label: 📊 Price Rating --- # 📊 Price Rating Thresholds **Settings → Devices & Services → Tibber Prices → Configure → 📊 Price Rating** --- Price ratings classify each 15-minute interval as **LOW**, **NORMAL**, or **HIGH** relative to the 24-hour trailing average. Sensors and automations can use these ratings to decide when to run appliances. See **[Ratings & Levels](sensors-ratings-levels.md)** for a full explanation of how ratings work and which sensors expose them. ## Settings | Setting | Default | Description | |---------|---------|-------------| | **Low threshold** | -10% | Prices this far below the trailing average → rated **LOW** | | **High threshold** | +10% | Prices this far above the trailing average → rated **HIGH** | | **Hysteresis** | 2% | Buffer zone around thresholds — prevents rapid flickering when a price hovers right at the boundary | | **Gap tolerance** | 1 | Smooths isolated rating blocks: a lone NORMAL interval surrounded by LOW on both sides gets corrected to LOW | ## How thresholds are applied ``` Trailing 24h average: 20 ct/kWh Low threshold: -10% → prices ≤ 18 ct → LOW High threshold: +10% → prices ≥ 22 ct → HIGH Everything else → NORMAL ``` Hysteresis adds an inner dead-band: once a rating is set to LOW, it stays LOW until the price rises above `18 ct + 2% = 18.36 ct`. This prevents sensors from flickering between LOW and NORMAL when prices are right at the boundary. ## Adjusting for your market **Markets with low daily price variation** (e.g., day typically stays within ±5%): - Lower the thresholds: try -5% / +5% - This keeps meaningful LOW/HIGH periods even on calm days **Markets with high daily variation** (e.g., ±30% swings): - Raise the thresholds: try -15% / +15% - This reserves LOW/HIGH for genuinely exceptional periods only - Consider using [Volatility](config-volatility.md) sensors alongside ratings on such days
