How to get device class version of state in a template

I’m using a template to show the state of a binary_sensor of device class of “presence”. However, it is currently showing on/off rather than home/away. Is there a way of getting the later in a template ?

Try this in your template

{% set state=states('your.binary.sensor') %}
            {% if state=='off' %}
            Home
            {% elif state=='on' %}
            Away
            {% else %}
            Home
            {% endif %}

Show a Dev tools → state screenshot for this sensor.
