Creating offsets in loveace to use with sun platform in automations

I have an automation which turns on and off my outside lights:

alias: 'Control Outside Lights '
description: Control outside Lights - morning and evening
trigger:
  - platform: sun
    event: sunrise
    offset: '-00:30:00'
  - platform: sun
    event: sunset
    offset: '-00:15:00'
  - platform: time
    at: input_datetime.outside_lights_off_morning
  - platform: time
    at: input_datetime.outside_light_off_evening
condition: []
action:
  - choose:
      - conditions:
          - condition: or
            conditions:
              - condition: sun
                after: sunrise
                after_offset: '-00:30:00'
              - condition: sun
                after: sunset
                after_offset: '-00:15:00'
        sequence:
          - service: switch.turn_on
            target:
              entity_id:
                - switch.outside_back_patio_current_value_3
                - switch.outside_front_entry_light_current_value_2
                - switch.ge_quick_fit_smart_in_wall_paddle_switch_current_value_9
      - conditions:
          - condition: or
            conditions:
              - condition: time
                after: input_datetime.outside_lights_off_morning
              - condition: time
                after: input_datetime.irrigation_valve_off_evening
        sequence:
          - service: switch.turn_off
            target:
              entity_id:
                - switch.outside_front_entry_light_current_value_2
                - switch.outside_back_patio_current_value_3
                - switch.ge_quick_fit_smart_in_wall_paddle_switch_current_value_9
    default:
      - delay:
          hours: 0
          minutes: 0
          seconds: 0
          milliseconds: 500
mode: single

I have read this from back in 2016.

Is it still the case that you cannot use templates for an offset? I have tried input_datetime and input_text and both failed.

Offset still does not accept template.

As an alternative, consider using Sun Elevation Trigger-

From the documentation-
“This is also useful when the “sunset” event is not dark enough outside and you would like the automation to run later at a precise solar angle instead of the time offset such as turning on exterior lighting.”

Thanks. I am checking this out. I would assume that you could then use an input_number to allow selection of the solar angle?
