Date calculation error

Configuration
1

Hello,

I am struggling to get the correct date from a sensor.
Mayby someone here can help me out?

The sensor is a scrape sensor the output is : Donderdag 8 februari

How can i convert this in a timestamp so it looks like 08-02-2018?

Thanks!
Sjef

What are you trying to do with the date?

Hi @petro,
I found a way to get the date i want by using a rest sensor instead of a scrape sensor to get the correct json value.

now i want to calculate with the date like this :

'{{ now().strftime("%Y-%m-%d") == (as_timestamp(states.sensor.afvalkalender_datum.state) - (24*3600)) | timestamp_custom("%Y-%m-%d") }}'

But i get this error when i use the (24*3600) in the automation :

Found the solution
i used this sensor :

- platform: rest
  name: afvalkalender_datum
  resource: http://inzamelkalender.hvcgroep.nl/push/calendar?postcode=1111XX&huisnummer=999
  value_template: '{{ (value_json.0.dateTime.0.date) }}'

before i used this value template :

  value_template: '{{ as_timestamp(value_json.0.dateTime.0.date) | timestamp_custom("%d-%m-%Y") }}'

Below the value_template to calculate the day to yesterday so i can use it in a automation:

  value_template: '{{ now().strftime("%Y-%m-%d") == (as_timestamp(states.sensor.afvalkalender_datum.state) - (86400)) | timestamp_custom("%Y-%m-%d") }}'

The full automation looks like this:

  • id: Rule_7_Trash
    alias: ‘Rule 7 Trash’
    trigger:
    • platform: time
      hours: 18
      minutes: 00
      seconds: 0
      condition:
    • condition: state
      entity_id: input_boolean.notify_trash
      state: ‘on’
    • condition: template
      value_template: ‘{{ now().strftime(“%Y-%m-%d”) == (as_timestamp(states.sensor.afvalkalender_datum.state) - (86400)) | timestamp_custom(“%Y-%m-%d”) }}’
      action:
    • service: notify.pushover
      data_template:
      message: ‘Het is vandaag - {{ now().strftime(“%Y-%m-%d”) }}. De {{ states.sensor.afvalkalender_type.state }} afvalbak wordt morgen geleegd!.’
      data:
      title: Trash!
      target:
      • “phone2”
      • “phone1”
