Allow duration from a template sensor

[FROCHE38]

Can you please add the availability to modify the duration (2 possibilities):

Solution 1
use Jinja in the YAML configuration file. Like

duration: "{{ states('sensor.iu_duree_erables_entree') }}"

sensor.iu_duree_erables_entree could always be in HH:MM:SS format using a template to convert it from minutes.

template:
  - sensor:
      - name: "IU Durée Érables entrée"
        unique_id: iu_duree_erables_entree
        state: >
          {% set m = states('input_number.duree_erables_entree')|int %}
          {{ '%02d:%02d:00' | format(m // 60, m % 60) }}

Solution2
Have a service (like the adjust_time) to set the duration from an automation
