Invert a attribute

Configuration
1

hello,
how can i invert this attribute here?

this here doesnt works:

- platform: template
  sensors:
    huehner_klappe_inv:
      value_template: >-
         {% if is_state('binary_sensor.huehnerstall_klappe_contact.contact', 'true') %}
         false
         {%- else -%}
         true
         {%- endif %}
      friendly_name: Huehnerstall Klappe Inv
      device_class: door

your template is wrong.

try this:

value_template: >
  {% if is_state_attr('binary_sensor.huehnerstall_klappe_contact', 'contact', 'true') %}
    false
  {%- else -%}
    true
  {%- endif %}

just a question: since this binary probably is on/off based on that attribute, you could also create a new template sensor based on the state of the binary itself?

{% set inversed = 'binary_sensor.updater' %}
{% if is_state(inversed,'off') %} on
{%- else -%} off
{%- endif %}

which can be shortened to:

      inversed_short:
        value_template: >
          {% set inversed = 'input_boolean.test' %}
          {{is_state(inversed,'off')}}

Right.

You didn’t create the contact attribute in the second binary sensor. You just created the binary sensor and controlled it’s state by referencing the attribute of the first sensor.

FYI, a simpler value template:

value_template: "{{ not is_state_attr('binary_sensor.huehnerstall_klappe_contact', 'contact', 'true') }}"
7

or:

{{is_state_attr('binary_sensor.huehnerstall_klappe_contact', 'contact', 'false') }}

which is essentially the same trick as I suggested above on the binary itself

close, but it’s an attribute so True/False are booleans not strings, which has been the issue from the beginning.

value_template: "{{ not state_attr('binary_sensor.huehnerstall_klappe_contact', 'contact') }}"

@noxx The inversion will be the main state of the sensor, not a contact attribute. If you want it to keep it an attribute…

- platform: template
  sensors:
    huehner_klappe_inv:
      value_template: >
        {{ states('binary_sensor.huehnerstall_klappe_contact') }}
      attribute_templates:
        contact: >
         {{ not state_attr('binary_sensor.huehnerstall_klappe_contact', 'contact') }}
