Do you think you will ever get there? 
if count_all > 0:
...
else:
count_all = 'All OK'
Then the state of the sensor should be ‘All OK’.
or
if count_all > 0:
...
else:
attributes['nuu_entities'] = 'All OK'
then the state will be 0 with an attribute nuu_entities: All OK
Sorry, no clue how to format the output of the attributes.
haha, well, we’re close! thanks to you fundamental perseverance on my questions…
got to admit this is very nice to have back:
open a folded row:
a more-info:
about the formatting: maybe Petro can come to the rescue 
will try and find a way to not-tag him…
must be something like
', '.join(list)
https://www.decalage.info/en/python/print_list
Yes, that was is!
# build the attributes
if count_all > 0:
if count_none > 0:
attributes['none_count'] = count_none
attributes['none_entities'] = ', '.join(sorted(list_none))
if count_unavailable > 0:
attributes['unavailable_count'] = count_unavailable
attributes['unavailable_entities'] = ', '.join(sorted(list_unavailable))
if count_unknown > 0:
attributes['unknown_count'] = count_unknown
attributes['unknown_entities'] = ', '.join(sorted(list_unknown))
if count_sensors > 0:
attributes['sensors_count'] = count_sensors
attributes['sensors_entities'] = ', '.join(sorted(list_sensors))
if count_all > 0:
attributes['all_count'] = count_all
attributes['all_entities'] = ', '.join(sorted(list_all))
this must be possible wit a dash in front of each item, but I have a déjà vu of difficulties with that…
ok, one more question…
Ive made an extra filter for unconditional entities (just like the original in fact, always leave out these entities_id’s)
if entity_id not in exclude_entities and entity_id not in exclude_conditional_entities and domain not in exclude_domains:
I tried to write that as
if entity_id not in [exclude_entities,exclude_conditional_entities] and domain not in exclude_domains:
but that simply does nothing, not even an error…
can’t we list several lists in a list like that to select from?
Found this:
thanks! unfortunately we cant import libraries like they mention there, give the fact we have a sandboxed python environment in HA.
made we want to try this though:
if hass.states.get('binary_sensor.outside_daylight_sensor').state == 'on':
exclude_conditional_entities = ['light.parking_light']
else:
exclude_conditional_entities = []
exclude_entities = ['group.battery_sensors','group.github_repos_in_use',
'group.github_repos_not_in_use','group.indoor_temp_sensors',
'group.iungo_switches_actueel','group.philips_temp_sensors']
excludes = exclude_conditional_entities + exclude_entities
and
if entity_id not in excludes and domain not in exclude_domains:
which seems to work as hoped for.
So, thanks for the pointer 
edit
small change:
for group in exclude_groups:
for entity_id in hass.states.get(group).attributes['entity_id']:
excludes.append(entity_id)
otherwise the entities from the external group weren’t taken into account in the addition of the 2 lists.
Now we can add the entities of that external group, and the conditional excludes and fixed excluded entities.
just to be able to see the unfiltered entities for the ['none', 'unavailable', 'unknown'] states, functional to be able to fine tune the filtering, I re-added the original small section.
also, I de-tabbed the attribute building, because I didn’t want these to be none and build under all circumstances, if only to be able to display that nicely in the Lovelace Frontend.
Also, I added some customization (…) on the main All sensor, to have an immediate place if all is ok. (we can’t customize entities in Ha Customize, that are created in Python scripts)
Below, I post the script and the Lovelace card. The external group and script to call this python script are all you need in HA config to get this going.
Hope this is of use for the community, have fun.

Nope… you do because names are long enough to not allow a second one to start on the same line, like my sensor.pond_control_box_humidity and the next one is too long to fit
If you have two short names, they’ll show more than one on a row
yes, you’re right, I see it now, will adapt
btw, I like it better like this, to conform with my other sensors:
as a side note, the card_mod of the headers per fold_entity_row did work once, but have lost their functionality:
.:
"#states > div:nth-child(n+1) > fold-entity-row":
$:
"#head > entity-row-maker > hui-section-row":
$: |
div.divider {height: 0px;}
div.label {font-weight: bold;}
would you know how tp get that to work?
also, the fold titles are to far to the right, and need a mod still, while the padding: 0 setting wrks fine for the entities in the fold:
using this now:
entities:
- sensor.uun_ordered
- entity: script.update_entities_uun
secondary_info: last-triggered
action_name: Update
- type: custom:fold-entity-row
head:
type: section
label: Details
entities:

padding: 0

margin: -16px -16px -16px -26px;
}
content: |
Count: {{state_attr('sensor.uun_ordered','unknown_count')}}
{{state_attr('sensor.uun_ordered','unknown_entities')}}
Have you tried clearing cache? any errors in the log?
No nothing really. Does it work on your side then?
No, everything seems aligned to the title though…
you mean the card_mod style doesn’t work? If not we have to find out how to get it to work (again), style the fold_entity_row header…it did before… see: How to style the fold-entity-row head? - #9 by Mariusthvdb
about the alignment: as said, in my case, all is well (aligned to the left side of the top thumbs, except for the header alignement, which is shifted too far to the right:
yours are all shifted right
btw, I’ve taken the card out of the top entities card, which allows for one less card_mod too:
type: custom:hui-element
card_type: entities
title: Unavailable Unknown None
show_header_toggle: false
style: |
ha-card {
box-shadow: none;
}
.card-header {color: var(--primary-color);font-weight: bold;}
# .:
# "#states > div:nth-child(n+1) > fold-entity-row":
# $:
# "#head > entity-row-maker > hui-section-row":
# $: |
# div.divider {
# height: 0px;
# }
# div.label {
# font-weight: bold;
# }
entities:
- sensor.uun_ordered
- entity: script.update_entities_uun
secondary_info: last-triggered
action_name: Update
alignment is solved, it was as easy as adding padding: 0 to the top fold… how I could have missed that. Had to adjust the other styles for the left side shift to -8px because of that:
- type: custom:fold-entity-row
head:
type: section
label: Details
padding: 0
entities:
- type: custom:fold-entity-row
head:
type: section
label: Unknown entities
padding: 0
entities:
- type: custom:hui-markdown-card
style: |
ha-card {
box-shadow: none;
margin: -16px -16px -16px -8px;
}
content: |
Count: {{state_attr('sensor.uun_ordered','unknown_count')}}
{{state_attr('sensor.uun_ordered','unknown_entities')}}
for all folds. and makes it looks perfect:
only thing left is to style the fold heads, can’t stand this is so difficult to find out…
Hi Marius,
Would you happen to have this issue as well? Each time I open a new HA instance or that I refresh, I’m getting this…
Refreshing 2-3 times, sometimes needs to clear cache (Ctrl+F5), but it eventually comes back to working good
That’s an old issue indeed. From the top of my head you can solve that using the hui-element custom card by Thomas loven and then add the markdown card in that
You were right… Here’s for posterity
Use this
- type: custom:hui-element
card_type: markdown
Instead of:
- type: custom:hui-markdown-card
Thanks 
card-preloaded caused issues still, or maybe put differently, didnt solve it all.
added to that is seemed to do so in a ‘hacky’ way, and not always, seemed a bit flaky. While hue-element solved all red cards, never seen a red card since using that. And so easy.
see this post from Thomas why probably: https://github.com/home-assistant/frontend/issues/4984#issuecomment-610781709
