Counts the lights on

Configuration
41

This will return a list

{%- set search_state = 'on' %}
{%- set search_area = 'Living Room' %}
{%- set ns = namespace(lights=[]) %}
{%- for light in states.light | selectattr('state','eq', search_state) if area_name(light.entity_id) == search_area %}
  {%- set ns.lights = ns.lights + [ light.entity_id ] %}
{%- endfor %}
{{ ns.lights }}

Works like a charm, thanks a lot. When trying to convert to count, i get it working but when i want to use it as a sensor, it fails (of course i hardcoded the search state search area and such instead of configurables, but can’t get it working). What am I doing wrong?

this works for sensor:

          {{ states | selectattr('entity_id','in', ['light.laundry_room','light.hobby_room_spot_2','light.hobby_room_spot_3','light.hobby_room_spot_1','light.living_room_color_1_table' ) |selectattr('state','eq','on') | list | count }}

but as soon as I add area_id or area_name to it, it fails to give me results.
Please assist

just use my template and change the last line to

{{ ns.lights | count }}
44

And how can I add that into a sensor? That’s whats not working, since ns.lights is something you predefined earlier, right?

45

you use the whole template in the template sensor

works perfectly, thanks so much!

Is it possible to avoid light groups to be counted (I can’t see an attribute like is_group or so) without hardcoding?

48

add a rejectattr('attributes.entity_id', '!=', undefined) to the for loop line before the if statement

Try this in the Template Editor (replace 'Kitchen' with the name of your area). I tested a similar version on my system and it correctly reported the number of switches (that are on) in the Kitchen area.

{{ expand('light.laundry_room', 'light.hobby_room_spot_2', 
          'light.hobby_room_spot_3', 'light.hobby_room_spot_1', 
          'light.living_room_color_1_table') 
   | selectattr('state', 'eq', 'on')
   | map(attribute='entity_id')
   | map('area_name')
   | select('eq', 'Kitchen')
   | list | count }}

That will work if you don’t want entity_id’s

51

Yes, that’s right but should be adequate for martheijnen who, unless I am mistaken, only requested a count.

52

you’re not mistaken, I was providing a list of entities

53

I have this code

sensor:
  - platform: template
    sensors:
      lucesencendidas:
        entity_id:
          - light.habitacion
          - light.mesita
          - light.sala
          - light.comedor
          - light.lectura
        #  - light.gateway_light_7811dcfab6cc
        #  #- switch.cocina
         # - switch.sonoff_1000649ca0 
         # - switch.sonoff_10005b8eb0 
        value_template: "{{  (states | selectattr('entity_id','in',state_attr('group.luces','entity_id')) | selectattr('state','eq','on') | list | count) }}"

It works but i don’t know why from 0 to 1 it counts inmediately, to update to other counts it takes a minute or so. Also happens when turning off (going down…). It takes time.
Anything about this issue?
I think that one two years ago (v.0.92) (i didn’t updated HA) it was working fine.

Does group.luces contain any of these entities?
- light.habitacion
- light.mesita
- light.sala
- light.comedor
- light.lectura

55

Yes all of these.

56

Whenever you use states in a template, the template is throttled to 1 update per minute.

Fix it by using this template instead:

        value_template: "{{  expand('group.luces') | selectattr('state','eq','on') | list | count) }}"
57

Yes all of these.

group:
  luces:
    name: IluminaciĂłn
    entities:
      - sensor.lucesencendidas
      - light.habitacion
      - light.mesita 
      - light.sala  
      - light.comedor
      - light.lectura
      - light.gateway_light_7811dcfab6cc
      - sensor.illumination_7811dcfab6cc
      - sensor.illumination_158d0003029a7a

Now…no delay.

If they’re all in the group then petro’s suggestion is the way to go.
