New module for natural sorting of sensor values

Configuration
1

If you sort sensor values or attributes with the “sort” filter, they get sorted by their ASCII value. But if you have numbers, the result ist not what you want:
{{ ["5","1","31","23","9","22","11"]|sort }}
gives you [‘1’, ‘11’, ‘22’, ‘23’, ‘31’, ‘5’, ‘9’]. So if you sort for example battery sensors, the list is not in the order you want it. So I developed a “natsort” filter. “natsort” splits text and numbers and sorts the numbers separate from the text.
So
{{ ["5","1","31","23","9","22","11"]|natsort }}
gives you [‘1’, ‘5’, ‘9’, ‘11’, ‘22’, ‘23’, ‘31’].
Another example for testing: battery values:
{{ states.sensor| selectattr('attributes.device_class', 'defined')|selectattr('attributes.device_class', 'eq','battery')|natsort(attribute="state")|list|join("\n\n") }}

If you want to test the natsort filter, download the file core/homeassistant/helpers/template.py at d7913562c42748053cce47f6cba515dfde472433 · martin3000/core · GitHub and replace template.py in homeassistant/helpers/template.py
And you have to install the python natsort module with

pip install natsort

.

all that and you still just couldn’t add to the manifest of the other integration? Most people will not be able to use this unless they run core or understand how to access the container (and install into the container every new release)

The ha_custom_filters integration did not work for me.
