# Glossary
|
|
|
|
Quick reference for terms used throughout the documentation.
|
|
|
|
## A
|
|
|
|
**API Token**
|
|
: Your personal access key from Tibber. Get it at [developer.tibber.com](https://developer.tibber.com/settings/access-token).
|
|
|
|
**Attributes**
|
|
: Additional data attached to each sensor (timestamps, statistics, metadata). Access via `state_attr()` in templates.
|
|
|
|
## B
|
|
|
|
**Best Price Period**
|
|
: Automatically detected time window with favorable electricity prices. Ideal for scheduling dishwashers, heat pumps, EV charging.
|
|
|
|
**Binary Sensor**
|
|
: Sensor with ON/OFF state (e.g., "Best Price Period Active"). Used in automations as triggers.
|
|
|
|
## C
|
|
|
|
**Currency Display Mode**
|
|
: Configurable setting for how prices are shown. Choose base currency (€, kr) or subunit (ct, øre). Smart defaults apply: EUR → subunit, NOK/SEK/DKK → base.
|
|
|
|
**Coordinator**
|
|
: Home Assistant component managing data fetching and updates. Polls Tibber API every 15 minutes.
|
|
|
|
## D
|
|
|
|
**Dynamic Icons**
|
|
: Icons that change based on sensor state (e.g., battery icons showing price level). See [Dynamic Icons](dynamic-icons.md).
|
|
|
|
## F
|
|
|
|
**Flex (Flexibility)**
|
|
: Configuration parameter controlling how strict period detection is. Higher flex = more periods found, but potentially at higher prices.
|
|
|
|
## I
|
|
|
|
**Interval**
|
|
: 15-minute time slot with fixed electricity price (00:00-00:15, 00:15-00:30, etc.).
|
|
|
|
## L
|
|
|
|
**Level**
|
|
: Price classification within a day (LOWEST, LOW, NORMAL, HIGH, HIGHEST). Based on daily min/max prices.
|
|
|
|
## M
|
|
|
|
**Min Distance**
|
|
: Threshold requiring periods to be at least X% below daily average. Prevents detecting "cheap" periods during expensive days.
|
|
|
|
## P
|
|
|
|
**Peak Price Period**
|
|
: Time window with highest electricity prices. Use to avoid heavy consumption.
|
|
|
|
**Price Info**
|
|
: Complete dataset with all intervals (yesterday, today, tomorrow) including enriched statistics.
|
|
|
|
## Q
|
|
|
|
**Quarter-Hourly**
|
|
: 15-minute precision (4 intervals per hour, 96 per day).
|
|
|
|
## R
|
|
|
|
**Rating**
|
|
: Statistical price classification (VERY_CHEAP, CHEAP, NORMAL, EXPENSIVE, VERY_EXPENSIVE). Based on 24h averages and thresholds.
|
|
|
|
**Relaxation**
|
|
: Automatic loosening of period detection filters when target period count isn't met. Ensures you always get usable periods.
|
|
|
|
## S
|
|
|
|
**State**
|
|
: Current value of a sensor (e.g., price in ct/kWh, "ON"/"OFF" for binary sensors).
|
|
|
|
**State Class**
|
|
: Home Assistant classification for long-term statistics (MEASUREMENT, TOTAL, or none).
|
|
|
|
## T
|
|
|
|
**Trailing Average**
|
|
: Average price over the past 24 hours from current interval.
|
|
|
|
**Leading Average**
|
|
: Average price over the next 24 hours from current interval.
|
|
|
|
## V
|
|
|
|
**Volatility**
|
|
: Measure of price stability (LOW, MEDIUM, HIGH). High volatility = large price swings = good for timing optimization.
