* Update query to include maxAge
Updated the query from recorded to include MaxAge if set; reducing the amount of records retrieved that would otherwise be purged anyway for the sensor.
* Added newline in docstring
Added newline in docstring.
* Add test + small fix
Added test to ensure query works correctly
Query should be greater then or equal instead of greater then. Fixed.
* Fixed lint issue
Fixed lint issue.
* always export max_age/min_age
* downgrade errors of missing data
on start with empty recorder database these errors are logged multiple times:
ERROR (MainThread) [homeassistant.components.sensor.statistics] mean requires at least one data point
ERROR (MainThread) [homeassistant.components.sensor.statistics] variance requires at least two data points
downgrade them to debug as they are not meaningful to end users
* add change_rate attribute
this calculates the average change rate of all data points
* simplify count, reorder attribute calculation
* reorder initialization
* reorder attribute names
* don't use min/max for min_age/max_age
* add test case
* style
* style
* sort constants
* init variables with None
* add precision config setting
* round to precision
* test round
* Fix statistics sensor mean and median when only one sample is available.
With only one data point stddev and variance throw an exception.
This would clear the (valid) mean and median calculations.
Separate the try..catch blocks for one-or-more and two-or-more stats so
that this doesn't happen.
Test this with a new sampling_size_1 test.
* test_statistics trivial whitespace fix
* Initializing statistics sensor with data from database
* fixed broken test case
* usage of recorder component is now optional, thx to @andrey-git
* added test case for initialize_from_database
