Count persons at home and show on icon badge

#1

I want to show how many person are at home on the icon badge.
What is the best way to achieve this.
In other systems I would use something like "IF xxx home and yyy home THEN badge=2, IF xxx home and yyy not home THEN badge=1 and so on but I dont know if IF THEN is allowed in HA.

Try something like this:

sensor:
  - platform: template
    sensors:
      people_home_count:
        entity_id: 
          - device_tracker.person_1
          - device_tracker.person_2
          - device_tracker.person_3
        value_template: >-
          {% set count = 0 %}
          {% if is_state("device_tracker.person_1", "home") %}
            {% set count = count + 1 %}
          {% endif %}
          {% if is_state("device_tracker.person_2", "home") %}
            {% set count = count + 1 %}
          {% endif %}
          {% if is_state("device_tracker.person_3", "home") %}
            {% set count = count + 1 %}
          {% endif %}
          {{count}}

I have tried it out with my device trackers but my log returns the following errors, but I am not quite sure what they mean.

  in "/home/homeassistant/.homeassistant/sensors.yaml", line 45, column 12

@jeppper Sorry about that, I wrote it at work so I didn’t get to test and yes I did have an error. Try it again, I edited the above post with the corrections.

no problem at all :slight_smile: I am glad for your help.
I still get an error though. Is “>-” after value_template correct?

2017-12-17 17:09:06 ERROR (MainThread) [homeassistant.config] Invalid config for [sensor.template]: invalid template (TemplateSyntaxError: unexpected '}', expected ')') for dictionary value @ data['sensors']['people_home_count']['value_template']. Got '{% set count = 0 %} {% if is_state("device_tracker.xxxxx", "home" %}\n  {% set count = count + 1 %}\n{% endif %} {% if is_state("device_tracker.xxxxx", "home" %}\n  {% set count = count + 1 %}\n{% endif %} {{count}}'. (See ?, line ?). Please check the docs at https://home-assistant.io/components/sensor.template/

@jeppper Copy the code again and then change the device_tracker. There were a couple of errors in my script (but I did correct it above) one of them was I forgot to close the brackets on the if statement lines, and I see from your error you still have that missing. You have:

{% if is_state(“device_tracker.person_1”, “home” %}

when it needs to be this:

{% if is_state(“device_tracker.person_1”, “home”) %}

so just delete what you have and paste the above script and change your device_trackers so all my bad code is gone :wink:

that did the trick :slight_smile: Now no errors shows up anymore and I get a badge with number of persons at home. I will test it more tomorrow when persons enter/leave the house.
Thanks very much for helping for now :+1:

I have now tried it out for some days and it works perfectly!! :grinning:
Anyhow I would like to use this “Count” result for showing on the iOS badge. Do you maybe know how?

Not exactly sure. I know you can set the badge with a push notification but unsure if it’s incremental or if it’s just set with the notification.

I have tried the following configuarion but nothing happens.

action:
  service: notify.ios_jespersiphone
  data:
    title: "Home"
    message: "xxx arrives"
    data_template:
      push:
        badge: "{{ states.sensor.people_home_count.state }}"

@jeppper I tried a few things as well, it looks like it doesn’t accept data_templates. As a workaround you could have multiple automations and a condition for each 1, 2, 3, 4 etc. people home and trigger the appropriate badge number. Not ideal, but it should work until templating is added.

I have tried to make multiple automations and it seems to Work :slight_smile:

A fix has just been rolled out server side to coerce badge to int.

Yes now it Works!! :slight_smile:
Now it would just be perfect if it would be possible to have the numbers on the badge showing without the need of a message.

You can now send a push with message set to delete_alert to not show a message.
