Function Documentation

◆ int_states_in_range()

int homeassistant.util.scaling.int_states_in_range ( tuple[float, float] low_high_range )

Given a range of low and high values return how many integer states exist.

Definition at line 61 of file scaling.py.

◆ scale_ranged_value_to_int_range()

int homeassistant.util.scaling.scale_ranged_value_to_int_range	(	tuple[float, float]	source_low_high_range,
		tuple[float, float]	target_low_high_range,
		float	value
	)

Given a range of low and high values convert a single value to another range.

Given a source low value of 1 and a high value of 255 and
a target range from 1 to 100 this function
will return:

(1,255), (1,100), 255: 100
(1,255), (1,100), 127: 49
(1,255), (1,100), 10: 3

Definition at line 6 of file scaling.py.

◆ scale_to_ranged_value()

float homeassistant.util.scaling.scale_to_ranged_value	(	tuple[float, float]	source_low_high_range,
		tuple[float, float]	target_low_high_range,
		float	value
	)

Given a range of low and high values convert a single value to another range.

Do not include 0 in a range if 0 means off,
e.g. for brightness or fan speed.

Given a source low value of 1 and a high value of 255 and
a target range from 1 to 100 this function
will return:

(1,255), 255: 100
(1,255), 127: ~49.8039
(1,255), 10: ~3.9216

Definition at line 31 of file scaling.py.

◆ states_in_range()

float homeassistant.util.scaling.states_in_range ( tuple[float, float] low_high_range )

Given a range of low and high values return how many states exist.
