Thanks for your reply.
I appli your code and it give me:

- id: '1593642521028'
  alias: Aspirateur
  description: ''
  trigger:
  - platform: template
    value_template: 'value_template: "{{ states(''sensor.date_time'') == (states.input_datetime.heure_passage_aspirateur.attributes.timestamp
      | int | timestamp_custom(''%H:%M'', True)) }}"'
  condition:
    {% if not is_state('input_select.aspi_'+nameday, 'Aucun')%}      #check if a script is selected in the inputselect
  action:
  - data:
      service_template: "script.{{ states('input_text.nameday') }}"      #launch the script

nameday is a sensor value who gives the name of the day (tuesday for exemple)
there is something wrong in the condition but i can’t make it work.

22 
  condition:
    condition: template
    value_template: "{{ not is_state('input_select.aspi_'+nameday, 'Aucun') }}"
23

:thinking:

where’s nameday coming from

24

it’s a date sensor:

      nameday:
        entity_id: sensor.date
        value_template: "{{ now().strftime('%A') }}"
25

but it isn’t declared in the template.

Hello,

  description: ''
  trigger:
  - platform: template
    value_template: '{{ states(''sensor.time'') == states(''input_datetime.heure_passage_aspirateur'')[0:5]
      }}'
  condition:
    condition: template
    value_template: "{{ not is_state('input_select.aspi_'+nameday, 'Aucun') }}" 
  action:
  - data:
      message: it work
    service: notify.notify

You can’t just put nameday in the template. It would need to be:

  value_template: "{{ not is_state('input_select.aspi_'+(states('sensor.nameday')|lower), 'Aucun') }}"

If you use that nameday sensor in a similar fashion elsewhere, it might be better to put the lowercase filter in the sensor:

nameday:
  entity_id: sensor.date
  value_template: "{{ now().strftime('%A')|lower }}"

fyi, filters do not require parenthesis, it’s redundant. Filters are always applied to the object that precedes them.

Why is now().strftime(’%w’) = 4 and now().weekday() = 3, thus off by 1 day? What am I missing here?

34

%w is based on Sunday being 0, now().weekday() is based on Monday being 0.
