Compensation
The Compensation integration consumes the state from other sensors. It exports the compensated value as state and the following values as attributes: entity_id and coefficients. A single polynomial, linear by default, is fit to all data points provided.
Configuration
To enable the compensation sensor, add the following lines to your configuration.yaml:
# Example configuration.yaml entry
compensation:
media_player_db_volume:
source: media_player.yamaha_receiver
attribute: volume_level
unit_of_measurement: dB
data_points:
- [0.2, -80.0]
- [1.0, 0.0]
Configuration Variables
The collection of data point conversions with the format [uncompensated_value, compensated_value]. e.g., [1.0, 2.1]. The number of required data points is equal to the polynomial degree + 1. For example, a linear compensation (with degree: 1) requires at least 2 data points.
An ID that uniquely identifies this sensor. Set this to a unique value to allow customization through the UI.
Attribute from the source to monitor/compensate. When omitted the state value of the source will be used.
The degree of a polynomial. e.g., Linear compensation (y = x + 3) has 1 degree, Quadratic compensation (y = x2 + x + 3) has 2 degrees, etc.
Defines the precision of the calculated values, through the argument of round().
