Known Devices - show only away

Configuration
1

I use Known Devices as a tool to help me see if a device is missing. My eyes scan thru a long list looking for Away ignoring Home.
Is there a way to only show the Aways?
Am I using the right tool for this task?
Should this be a feature request?
Thanks

What are you trying to do?

Monitor whether devices on your network are working? There’s tools like Xymon, Zabbix, Nagios and others for that.

Regardless, you should be looking to automate, not doing it manually.

If you have all devices you want to track in a group called ‘devices’ you can use this in a template to show a list of devices that is currently offline, or better: not_home

    {%- for entity_id in states.group.devices.attributes.entity_id -%}
      {% set parts = entity_id.split('.') -%}
      {%- if states(entity_id) == 'not_home' %}
      {%- if loop.first %} {% elif loop.last %}, {% else %}, {% endif -%}{{ states[parts[0]][parts[1]].name }}{% endif -%}
    {%- endfor %}
