For Loop - Battery Level Sensor

Configuration
1

I have a question related to creating a for loop to declare sensors. For example, I have several door/window sensors and have a dedicated page that shows current battery level percentage. It seems rather inefficient to declare each one individually when I can filter out the devices I need (see snippet below). Is there a way to transfer this “query” to instantiate sensors? I’m pretty new to this stuff so any help/direction would be greatly appreciated.

Loop to gather the sensors I need that have a battery

{% for state in states.zwave %}
{% if state.attributes.battery_level is defined %}
  {{ state.entity_id}} = {{ state.attributes.battery_level }}
{% endif %}
{%- endfor -%}

Sensor declaration

- platform: template
  sensors:
    first_sliding_door_battery_level:
      friendly_name: 'First Floor Sliding Door - Battery'
      value_template: '{{ states.zwave.first_sliding_door.attributes.battery_level }}'
      unit_of_measurement: '%'
2

nope.
