Correct wording for binary sensors / native support of states per sensor class (0/off/low/closed/false and 1/on/high/open/true)

As suggested by fabaff here I open this feature request to improve basic functionality of sensors.

At the moment I have this config:

Excerpt of configuration.yaml:

    !include customize.yaml

Excerpt of customize.yaml:

#Open/Close Windows/Door Sensors
      friendly_name: 'living entrance door'
      device_class: opening

This results in panels/cards like this:

A sensor with class opening should show up with open/closed (now its on/off).

The other sensors are described here:
There you can find the other states that would be nice to show up.

For the sake of completeness:
@fabaff kindly offered this working solution to achieve correct states:

  - platform: template
        value_template: '{% if is_state("input_boolean.control_switch", "off") %}close{% else %}open{% endif %}'
        friendly_name: 'Open_Close'

You link to the issue isn’t working. Pasted below…

Thank you! Edited it accordingly.

Would like this functionality added.

For me I am trying to include trigger_to. friendly state in my messages.

So a door message would say the door is now “open” in my message rather than the door is now “on”
