Hello, oui c l’idée là j’affiche l’alerte qui valider que tt fonctionne bien 
Je pense que je vais devoir faire pas du code sup pour récup les concentrations pour créer le sensor qui correspond
Comme on dit: stay tunned ^^
edit: @WarC0zes cadeau ^^
The Code
type: custom:auto-entities
card:
square: false
type: grid
columns: 1
card_param: cards
filter:
template: |-
{% for entity_id in integration_entities('atmofrance') -%}
{%- if 'pornichet' in entity_id and 'niveau_' in entity_id -%}
{%- set myname = state_attr(entity_id, 'friendly_name') | replace('-Pornichet', '') | replace('Niveau ', '') -%}
{%- set my_concentration_sensor = ('sensor.concentration_' + myname + '_pornichet') | lower | replace('é', 'e') -%}
{%- set my_concentration_state = '${card.querySelector(' + "'.bubble-state'" + ').innerText = ' + "'" + states(my_concentration_sensor) + ' µg/m³' + "' }" -%}
