will check that. Though I am updating soon, so wont rely too much on the current possibilities of 84.3 
should be future proof!
No problem! I think I’ve got the framework put together in my head, should be able to get this coded tonight or tomorrow.

yes, was familiar with that, but wouldn’t directly know how to use that in this setting. before, Ive use python scripts to create sensors with long attributes successfully.
Ill see what your suggestion brings, might just be an easy way out here. 
For anyone using a recent version of Home Assistant, this works:
- platform: rest
name: My Config
resource: http://localhost:8123/api/config
authentication: basic
value_template: "{{ value_json.version }}"
json_attributes:
- components
- unit_system
- config_dir
headers:
Content-Type: application/json
Authorization: !secret api_bearer_token
User-Agent: Home Assistant REST sensor
api_bearer_token is a string (in secrets.yaml) containing:
api_bearer_token: Bearer <your long-lived access token goes here>

I knew I saw loaded components somewhere and I have been looking everywhere to try and find it. I wanted to do exactly what you are trying to achieve. Cheers
Glad I came and checked this thread before I started working on a Python script!
@Mariusthvdb does this satisfy what you’re looking for? If you want to display it as a sorted, formatted list in Lovelace, you can use the new card-templater card and apply it to a Markdown card with the following template:
{% for component in states.sensor.my_config.attributes.components|sort -%}
{{ component + "\n"}}
{%- endfor %}

yes it does, and its working. on my ha 84.3 system I need the authorization using the bearer token, for my 92.1 system I can use below configuration …without authentication, from another instance that is, havent checked in on the system itself yet)
using this:
- platform: rest
name: Hassio Main config
resource: https://mydomain.duckdns.org:8123/api/config
value_template: "{{ value_json.version }}"
json_attributes:
- components
- unit_system
- config_dir
! Thanks @123!
please help me get this into a python script
{% for component in state_attr('sensor.hassio_main_config','components')|sort -%}
{{ component + "\n"}}
{%- endfor %}
so I can use
state = hass.states.get('sensor.hassio_main_config').state
components = state.attributes.get('components')
hass.states.set('sensor.components', len(components), {
'custom_ui_state_card': 'state-card-value_only',
'text': components
})
using that custom_ui_state_card, I can show the card in regular HA too!
Can we get the domains like this too? The state of the template sensor in my first post is way too long also, so if we could get that in to an attribute via the rest api that would be very nice indeed.
https://mydomain.duckdns.org:8124/api/services and then some nifty value_template to sort the domain names only?
I’m a little out of my depth on this one, as I pretty much went straight to Lovelace UI when I started with Home Assistant, and I’m not really familiar with custom_ui_state_card.
never mind the state card, thats only to represent the outcome in a regular HA card and can’t show more than max 255 characters.
Im now trying to get the components in this python script… maybe you would be know how to help, I seem to have forgotten the correct syntax… been a while since I wrote my last python ;-(
same goes for the domains sensor. I can now only show the number of domains, nt the domains themselves.
update
found it… duh
components = hass.states.get('sensor.hassio_main_config').attributes['components']
hass.states.set('sensor.components', len(components), {
'custom_ui_state_card': 'state-card-value_only',
'text': components
})
would you please be able to give me the code for that?
havent used that card before, this might be a fine reason to start…
Yes, I was going to put it together tonight. I’ll post it when it’s done.
well, finally made some progress, showing in regular HA:
now I want to ‘unlist’ this showing each component on its own line, and dont show the brackets and quotes. Also want to list them alphabetically, but thats of second concern.
Should be very easily be able to do that with the for loop, but didn’t get the correct syntax yet, please have a look?
after that I can simply substitute the format(components) with format(line)…
components = hass.states.get('sensor.hassio_main_config').attributes['components']
for c in components:
state = hass.states.get(c)
line = '{}\n'.format(state)
text = '*========== {} Loaded Components ========\n' \
'+{}' \
.format(len(components),
components)
hass.states.set('sensor.hassio_main_components', len(components), {
'custom_ui_state_card': 'state-card-value_only',
'text': text
})
This is doing nothing in your code. Why have it?
This will get you everything on it’s own line.
components = hass.states.get('sensor.hassio_main_config').attributes['components']
components.sort()
text = ['*========== {} Loaded Components ========'.format(len(components))]
text = text + components
text = '\n'.join(text)
hass.states.set('sensor.hassio_main_components', len(components), {
'custom_ui_state_card': 'state-card-value_only',
'text': text
})
Indeed, it just showed it to give an idea of what I was looking for. and yes, your code works, thank you!
could I order that alphabetically also?
Since this is a very long card now (… i know, i asked for it) maybe format it as a comma separated listing (still without the quotes and brackets?
like this:
text = ', '.join(text)
updated the code to handle sorting
there’s a bit of a caveat: Id need the header to have another color code (* in this case ) than the rest of the list. Right now the * works on the full text , since you add the header to that text and the following lines consecutively. Somehow Id love to be able to separate those.
that’s the way the custom-ui card works. Example of another card:
busted=""
busted_badge=""
if (len(results)) > min_items_to_show or show_if_empty:
visible = True
for e in results:
line = '{} in: {}'.format(e, ','.join(grouped_entities[e]))
busted = '{}!- {}\n'.format(busted,line)
busted_badge = '{}{}\n'.format(busted_badge,line)
friendly_name_badge = len(results)
else:
visible = False
busted = '!- All busted, {} Ghosts found!\n'.format(len(results))
busted_badge = 'No Ghosts found\n'
friendly_name_badge = 'All busted'
ghost_card = '*=========== Ghosts ===========\n' \
'{}\n' \
'*========= Entity count =========\n' \
'!- {} entities to list\n' \
'#- {} real entities\n' \
'+- {} grouped entities\n' \
'+- {} groups processed\n' \
'*========== Settings ===========\n' \
'/- targetting group: {}\n' \
'$- ignoring {} items:\n' \
'%|-> {}\n' \
'$- ignoring {} domains:\n' \
'%|-> {}' \
.format(busted,
len(results),
len(real_entities),
len(grouped_entities),
len(processed_groups),
target_group,
len(ignore_items),
ignore_items_unlist,
len(ignore_domains),
ignore_domains_unlist)
hass.states.set('sensor.ghosts_sensor', len(results), {
'custom_ui_state_card': 'state-card-value_only',
'text': ghost_card,
})
showing as:
what indicates the color code?
found it as I corrected my post above…
see: ‘*’ for bold:
‘+’ for green:
##########################################################################################
# Codes for text_colors declared in
# Custom card: /custom_ui/state-card-value_only.html
# changed to use below customizing options:
##########################################################################################
# case "*": return "bold";
# case "/": return "italic";
# case "!": return "red";
# case "+": return "green";
# case "=": return "yellow";
# case "%": return "grey";
# case "$": return "brown";
# case "#": return "blue";
# default: return "normal";
ah, try this
components = hass.states.get('sensor.hassio_main_config').attributes['components']
cnt = len(components)
components.sort()
components = ', '.join(components)
text = '*========== {} Loaded Components ========\n+'.format(cnt)
text = text + components
hass.states.set('sensor.hassio_main_components', len(components), {
'custom_ui_state_card': 'state-card-value_only',
'text': text
})
tried it but that results in the same, because there is still text = text + components.
This works:
components = hass.states.get('sensor.hassio_main_config').attributes['components']
components.sort()
components = ', '.join(components)
text = '*========== {} Loaded Components ========\n' \
'{}' \
.format(len(components),
components)
hass.states.set('sensor.hassio_main_components', len(components), {
'custom_ui_state_card': 'state-card-value_only',
'text': text
})
though now my count is off…
so changed a bit:
components = hass.states.get('sensor.hassio_main_config').attributes['components']
count = len(components)
components.sort()
list = ', '.join(components)
text = '*========== {} Loaded Components ========\n' \
'{}' \
.format(count,
list)
hass.states.set('sensor.hassio_main_components', count, {
'custom_ui_state_card': 'state-card-value_only',
'text': text
})
bingo:
thanks!
