Sensor - Count the installation (Mine is bigger than yours-sensor)

[riro (Rikard Ronnkvist)]

A simple sensor that counts all other sensors

sensor:
- platform: template
  sensors:
    hass_count:
      friendly_name: HASS Count
      icon_template: mdi:home-assistant
      value_template: "{{ states | count }}"
      attribute_templates:
        automation: "{{ states.automation | count }}"
        binary_sensor: "{{ states.binary_sensor | count }}"
        camera: "{{ states.camera | count }}"
        climate: "{{ states.climate | count }}"
        device_tracker: "{{ states.device_tracker | count }}"
        light: "{{ states.light | count }}"
        media_player: "{{ states.media_player | count }}"
        scene: "{{ states.scene | count }}"
        script: "{{ states.script | count }}"
        sensor: "{{ states.sensor | count }}"
        switch: "{{ states.switch | count }}"
        zwave: "{{ states.zwave | count }}"

To list all domains (and current count) in your environment you can run this:

{%- for d in states | groupby('domain') %}
{{ d[0] }} - {{ states[d[0]] | count  }}
{%- endfor %}

And the result

[arretx (Jon Griffith)]

Groovy. Thanks for the code.

[tom_l]

I have no need for the card so I just did it in the template editor:

[riro (Rikard Ronnkvist)]

Did a small update to the script on the first post to include current count .

[tom_l]

Thank you. I was trying to get this to work:

{%- for d in states | groupby('domain') %}
{{ d[0] }} - {{ states[d[0]] | count  }}
{%- endfor %}

But stupidly I was using states.d[0] | count

[VDRainer]

Here is a python_script where you don’t have to specify the domains.

[Mutt (Muttley)]

@tom_l

{%- for d in states | groupby('domain') %}
{{ d[0] }} - {{ states[d[0]] | count  }}
{%- endfor %}

Rikard and Tom’s is much neater than what I use : -

states : {{ states| count }}
{%- set ns = namespace(num = 0) %}
{% for domain in states | map(attribute='domain') | unique %}
{%- set numb = states[domain] | count %}
{%- set ns.num = ns.num + numb %}
{{ domain ~ 's : ' ~ numb }}
{%- endfor %}

Producing : -

But don’t get into a pissing contest with @Mariusthvdb , He’ll eat you alive !

[Mariusthvdb (Marius)]

yeah, the beauty of this python script is it does it all automatically:

count_all = 0
domains = []
attributes = {}

for entity_id in hass.states.entity_ids():
    count_all = count_all + 1
    entity_domain = entity_id.split('.')[0]
    if entity_domain not in domains:
        domains.append(entity_domain)

attributes['Domains'] = len(domains)
attributes['--------------'] = '-------'

for domain in sorted(domains):
    attributes[domain] = len(hass.states.entity_ids(domain))

attributes['friendly_name'] = 'Entities'
attributes['icon'] = 'mdi:format-list-numbered'

hass.states.set('sensor.overview_entities', count_all, attributes)

though I like the way the OP uses the attribute_templates (I still have these (also) as individual sensors, per domain)
Cut another 30 entities (not are this relieves the state machine, because they still are listed in the attributes as templates.

only gripe I have here, is it counts my light groups to, since they belong to the domain light. here my light sensor isnt

{{states.ligh |count}}

but

      count_lights:
        entity_id: sensor.date
        friendly_name: Lights (only)
        value_template: >
          {{expand('group.all_lights_only')|count}}

@Mariusthvdb

49 Proximity sensors.
34 Zones.

Are you sure you are not automating a small country?

I didn’t bother with sensors, I just put mine straight into a markdown card (someone is going to tell me why that is a bad idea…)

[Mariusthvdb (Marius)]

@klogg

Are you sure you are not automating a small country?

no, just a large family

did a small rewrite of the OP sensor with attribute_sensors and will test this shortly:

      entities_domains_counter:
        entity_id: sensor.date  #<--- not sure if this needs to stay coming 115? maybe to keep it from updating too frequently;-)
        friendly_name: Entities per domain

btw, Maybe I am overly puristic, but I don’t like the fake icon_templates, so took the out and customize it

sensor.entities_domains_counter:
  icon: mdi:home-assistant

I know it’s 1 line extra, but the dev’s wont complain if anything goes awol…

bw, missed an important 1: persistent_notifications. But I already had that in my notification package, so added the attibute as

          persistent_notification: >
            {{states('sensor.count_persistent_notifications')}}

You lost 30 sensors. Did one of your zones attempt to proclaim its independence and many sensors were destroyed in the ensuing battle?

[Mariusthvdb (Marius)]

even worse!
Ive lost several Waze sensors, and Weatherbit integration:
at startup

after a while

the culprits:

[VarenDerpsAround (Roldy Buffalo)]

Roldy's Home Assistant - 190+ sensors - 440+ entities - 70+ automations - Floorplan

I would like to share my home assistant configuration example for the rest of the community to check out and hopefully get some ideas! (If you would like an example specifically, let me know) [hass cover] [floor_plan] [grand_count] [Wyze Sensors] [pi_stats] [nuc_stats] [image]

[Mariusthvdb (Marius)]

hi!
not sure why you’d post that, but if your ‘pulling the data’ from this Roldy's Home Assistant - 190+ sensors - 440+ entities - 70+ automations - Floorplan you now should have noticed that could be done much better…

consider that code:

   count_automations:
     entity_id: sensor.date
     value_template: >
       {%- set domains = ['automation'] -%}
       {%- for domain in domains -%}
         {%- for item in states[domain] -%}
           {% if loop.first %}
             {{loop.length}}
           {% endif %}
         {%- endfor -%}
       {%- endfor -%}

and compare it to

{{states.automation|count}}

[tom_l]

Hey @uiguy come here and blow their minds…

Template editor tool:

{%- for d in states | groupby('domain') %}
{{ d[0] }} - {{ states[d[0]] | count  }}
{%- endfor %}

[uiguy]

my code on @Mariusthvdb link above came initially from @Mariusthvdb i seem to remember… oh and sorry I did not credit you before…

[atomicpapa (Glenn Morrison)]

@tom_l

{%- for d in states | groupby('domain') %}
{{ d[0] }} - {{ states[d[0]] | count  }}
{%- endfor %}

So, I threw this into the Template editor and it popped up a long list of domains as it should, but one in particular caught my eye -
sensor - 666
Thanks 2020!

[sparkydave (🇦🇺 Dave)]

What would be the best way to display this in Lovelace? I tried a Markdown Card but the formatting was ugly, not having each domain on a new line. Is there a way for format the use of new lines in the Markdown Card?

[tom_l]

I tried to put it in a table but failed. This is the best I can do.

type: markdown
content: |-
  {% for d in states|groupby('domain') %}
  **{{ d[0]|replace('_', ' ')|title }}**  {{ states[d[0]]|count  }}
  {%- endfor %}
title: Domain Counts
