I have copied a template from https://smarthomepursuits.com/display-offline-unavailable-or-missing-sensors-in-home-assistant/ and it did what it should. It shows unavailable entities.
But I wonder if it is possible to show the friendly name of the entities instead of the entity id. I have tried to understand the template and i have read the docs regarding templating, jinja and yaml but still my skills are low.
So could someone please help me? Thank you in advance.
Here ist the template:
- platform: template
sensors:
unavailable_entities:
friendly_name: Unavailable Entities
unit_of_measurement: entities
icon_template: "{{ 'mdi:check-circle' if is_state('sensor.unavailable_entities','0') else 'mdi:alert-circle' }}"
value_template: >
{{ states|selectattr('state','in',['unavailable','unknown','none'])|rejectattr('domain','eq','group')
|rejectattr('entity_id','in',state_attr('group.ignored_entities','entity_id'))|list|count }}
attribute_templates:
entities: >
{{ states|selectattr('state','in',['unavailable','unknown','none'])|rejectattr('domain','eq','group')
|rejectattr('entity_id','in',state_attr('group.ignored_entities','entity_id'))|map(attribute='entity_id')|list }}
