Data_template, ios_notify: loop through group and add text if

Thanks for staying with me so far!

I’m currently thinking about this:

{% set conditionResult = [] %}
  {% for entity_id in states.group.all_gas_stations.attributes.entity_id %}
        {% set domain, device = entity_id.split('.') %}
        {% if (states[domain][device].state |float < states.input_number.slider1.state |float) %}
{% if 1 == 1 %}          
{% set x = conditionResult.append('True') %}{%endif%}
        {%- endif -%}
        {% if loop.last %}
        {{conditionResult|length >1}}
        {%endif%}

      {%endfor%}
       {# {{resultVar |length >1}} #}

I know the code seems strange, especially the "{% if 1 == 1 %} " part and the line below. But I learned from other posts here that this is required to circument other errors :slight_smile: :man_shrugging:

Problem is, the rendering engine gives me this error, and there is just one google hit on it:

Error rendering template: SecurityError: access to attribute 'append' of 'list' object is unsafe.

I’m also looking into macros to see if there is a way to overcome the limitations of Jinja.

I’ll keep you posted :wink:
