Trying to add minutes to sunset time via helper number

Configuration

#1

Hi there,
I have a number helper I created, which stores the minutes the closing of a chicken hen door should be delayed after sunset. That helper is input_number.klappe1_offset_su_helper. That number is stored as a string, I believe. At least that’s what most forum entries say.

I’m trying to add those minutes to the next sunset time. I tried to to create a template like this:

  - trigger:
      - platform: time
        at: '00:00:00'
      - platform: event
        event_type: event_template_reloaded
      - platform: homeassistant
        event: start
    sensor:
      - name: "Klappe1 mit Offset"
        unique_id: "klappe1_sunrise_with_offset"
        state: "{{ state_attr('sun.sun', 'next_setting') | as_datetime + (states('input_number.klappe1_offset_su_helper')|int * 60))|timestamp_custom('%H:%M:%S', false)}}"

This throws me an error: “TypeError: can only concatenate str (not “int”) to str”. I tried to find a solution in the forums, but after a day I’m stuck. Does anyone have an idea and can point me in the right direction? How do i convert the string to an integer and add it to the datetime?

Any help would be greatly appreciated, thanks in advance!

        state: >
          {{ (state_attr('sun.sun', 'next_setting') | as_datetime + 
             timedelta(minutes = states('input_number.klappe1_offset_su_helper') | int(0))).timestamp() 
             | timestamp_custom('%H:%M:%S', false) }}

Copy-paste it into the Template Editor and confirm it doesn’t contain any errors and reports the desired result.

wow, great. Thanks a lot, that’s a good start. It does add the minutes to the UTC time.

This does show the local sunset, 2022-07-03 21:49:16.111203+02:00

state: >
          {{ state_attr('sun.sun', 'next_setting') | as_datetime | as_local  }}

This shows 20:19:16 as a result, I’m adding 30 Minutes.

state: >
          {{ (state_attr('sun.sun', 'next_setting') | as_datetime | as_local  + 
             timedelta(minutes = states('input_number.klappe1_offset_su_helper') | int(0))).timestamp() 
             | timestamp_custom('%H:%M:%S', false) }}

any idea why?

Have you tried setting this to ‘true’? Nevermind, dumb idea, haven’t read the complete posts, sorry for confusion! :slight_smile:

Do you want to show the time as local or in UTC?

That’s what is controlled by the second argument in your timestamp_custom function (true/false).

Thanks guys, you all made my day, that’s that. This was driving me crazy and now I feel i should have somehow found that out myself… :slight_smile:

For future reference, the full code is:

state: >
          {{ (state_attr('sun.sun', 'next_setting') | as_datetime | as_local  + 
             timedelta(minutes = states('input_number.klappe1_offset_su_helper') | int(0))).timestamp() 
             | timestamp_custom('%H:%M:%S', true)}}
