Input_datetime

Configuration
1

I have two variables declared in configuration.yaml:
input_datetime:
nextcooldperiod:
name: “Prochaine periode froide”
has_date: true
has_time: true

coldperiodeduration:
name: “Duree periode froide”
has_date: false
has_time: true

I see the variable coldperiodduration in the developpement tool.
My script is:

alias: "cold_period"
trigger:
    platform: time
    at: input_datetime.nextcooldperiod
action:
  - service: notify.email
    data:
      title: "Home assistant warning"
      message: "Evenement periode froide Hydro Quebec"
      
  - service:  input_boolean.turn_on
    data:
      entity_id: input_boolean.over_heating
    
 # - delay: '00:55:00'
  - delay: '00:00:10'
  
  - service: notify.email
    data:
      title: "Home assistant warning"
      message: "will turn off over heating "
  
  - service:  input_boolean.turn_off
    data:
      entity_id: input_boolean.over_heating
      
  - service: notify.email
    data:
      title: "Home assistant warning"
      message: "Will tunr on save electricity"
  
  - service:  input_boolean.turn_on
    data:
      entity_id: input_boolean.save_electricity
      
  - service: notify.email
    data:
      title: "Home assistant warning"
      message: "Duration of the cold period: {{input_datetime.coldperiodeduration}} "
    
  - delay: input_datetime.coldperiodeduration
  
  - service:  input_boolean.turn_off
    data:
      entity_id: input_boolean.save_electricity
          
  - service: notify.email
    data:
      title: "Home assistant warning"
      message: "Fin de la periode froide Hydro Quebec"

And, I have followings error in logs:

What’s wrong ?

Thanks for your help !

I prefer to declare stuff like input_datetime as an helper in the configuration, you’ll get dialogs to configure it, here:

Much easier for the beginner that I am.

Else make sure it exists in dev tools / states, look for input_datetime.nextcooldperiod. If it doesn’t exist, it’s a bad YAML configuration

I believe the problem you have reported here is related to a problem you have posted in two other places:

This is incorrect:

  - delay: input_datetime.coldperiodeduration

In your other posts, this is also incorrect:

- delay: {{states(‘input_datetime.coldperiodeduration’)}}

Change it to:

- delay: "{{states('input_datetime.coldperiodeduration')}}"

For the record, the post you have marked as being the Solution (i.e. use Configuration > Helpers to create an input_datetime entity) doesn’t solve the problem you reported.

It doesn’t matter if you define the input_datetime via the UI or in configuration.yaml. The problem is that the template using the input_datetime is incorrect.

In addition, I’ve noticed you have attempted to mark several posts within the same thread with the Solution tag. This is not possible. Only one post in a thread can have the Solution tag.

thanks for your reply.
I was very disapointed, but now I have solved the automation.

Best regards
