Jinja2 Template Examples

Check if a driver is under investigation:

{% set investigations = state_attr('sensor.f1_investigations', 'under_investigation') %}
{% set ver_involved = investigations | selectattr('drivers', 'contains', 'VER') | list %}
{% if ver_involved | length > 0 %}
  VER is under investigation!
{% endif %}

List all pending penalties:

{% set penalties = state_attr('sensor.f1_investigations', 'penalties') %}
{% for p in penalties %}
  {{ p.driver }}: {{ p.penalty }} ({{ p.reason }})
{% endfor %}

Count active investigations:

{% set noted = state_attr('sensor.f1_investigations', 'noted') | length %}
{% set investigating = state_attr('sensor.f1_investigations', 'under_investigation') | length %}
Noted: {{ noted }}, Under Investigation: {{ investigating }}

Get post-race investigations:

{% set investigations = state_attr('sensor.f1_investigations', 'under_investigation') %}
{% for inv in investigations if inv.after_race %}
  {{ inv.drivers | join(' vs ') }} - {{ inv.reason }} (after race)
{% endfor %}

Show recent NFI decisions:

{% set nfi = state_attr('sensor.f1_investigations', 'no_further_action') %}
{% for item in nfi %}
  {{ item.drivers | join('/') }}: No Further Action ({{ item.reason }})
{% endfor %}

Create investigation summary:

{% set sensor = 'sensor.f1_investigations' %}
{% set total = states(sensor) | int %}
{% if total > 0 %}
  {{ total }} active matter{{ 's' if total > 1 else '' }}:
  {% set penalties = state_attr(sensor, 'penalties') %}
  {% for p in penalties %}
    - {{ p.driver }}: {{ p.penalty }}
  {% endfor %}
{% else %}
  No active investigations
{% endif %}
