So, I was looking to report on all devices in an area. This led me to looking for a list of areas and devices. Then, listing of devices not in an area.
I am not sure all of this is in one place. So, I thought I’d post it here.
All of these are using tables in Markdown Cards. But, could certainly be used in other ways. You can decide your best method to use them.
They are all setup to sort by area/device name entered by user (or name if not entered) or device name entered by user (or name if not entered)/area depending on the layout.
First, all areas and a list of devices in that area:
|Area|Devices
|:---|---:
{%- set ns = namespace(areas = [], devices=[], area_name = '') -%}
{%- for area in areas() | sort %}
{%- set ns.area_name = area_name(area) -%}
{%- set ns.devices = [] -%}
{%- for device in area_devices(area) %}
{%- set ns.devices = ns.devices + [{'device_name': device_attr(device, 'name_by_user') if device_attr(device, 'name_by_user') != none else device_attr(device, 'name')}] -%}
{%- endfor %}
{%- set ns.areas = ns.areas + [{'area_name': area_name(area),
'devices': ns.devices}] -%}
{%- endfor -%}
{%- for area in ns.areas | sort(attribute='area_name') -%}
{%- if area.devices | length == 0 %}
| {{ area.area_name }} | None
{%- else -%}
{%- set ns.area_name = area.area_name -%}
{%- for device in area.devices | sort(attribute='device_name') %}
| {{ ns.area_name }} | {{ device.device_name }}
{%- set ns.area_name = '' -%}
{%- endfor -%}
{%- endif -%}
{%- endfor -%}
This shows:

Second is a list of devices and the areas they are in.
|Device|Area
|:---|:---
{%- set ns = namespace(devices = []) -%}
{%- for entity in states | map(attribute='entity_id') %}
{%- if device_id(entity) %}
{%- set ns.devices = ns.devices + [{'id': device_id(entity),
'name': device_attr(entity, 'name_by_user') if device_attr(entity, 'name_by_user') != none else device_attr(entity, 'name'),
'area': area_name(device_attr(entity, 'area_id'))}] -%}
{%- endif -%}
{%- endfor -%}
{%- for device in ns.devices | unique(attribute='id') | sort(attribute='name') %}
| {{ device.name }} | {{ device.area }}
{%- endfor -%}
This shows:
Finally, a list of devices NOT in an area.
|Device|Area
|:---|:---
{%- set ns = namespace(devices = []) -%}
{%- for entity in states | map(attribute='entity_id') %}
{%- if device_id(entity) %}
{%- set ns.devices = ns.devices + [{'id': device_id(entity),
'name': device_attr(entity, 'name_by_user') if device_attr(entity, 'name_by_user') != none else device_attr(entity, 'name'),
'area': area_name(device_attr(entity, 'area_id'))}] -%}
{%- endif -%}
{%- endfor -%}
{%- for device in ns.devices | selectattr('area', 'eq', none) | unique(attribute='id') | sort(attribute='name') %}
| {{ device.name }} | {{ device.area }}
{%- endfor -%}
This shows:

I think I have provided all of what I have built. Please let me know if something is wrong or can be optimised.
