Why doesn't this automation work?

[pseudo prawn]

Desired automation => Turn on a light after sunset (when it's of) if someone came through the gate and next opens the backdoor. This is what I came up with, but this automation doesn't work (have absolutely no clue why it doesn't work???)

alias: Zet licht aan na poort en deur
description: >-
Zet het licht aan nadat de poort sensor is geactiveerd en daarna de deur
sensor binnen 3 minuten.
triggers:

• type: opened
  device_id: 5301ba3796c4fac171ad67d609cb8636
  entity_id: d961279e26574f58304e784970b4a639
  domain: binary_sensor
  trigger: device
  conditions:
• condition: template
  value_template: >

  as_timestamp(states.binary_sensor.deursensor_poort_tuin.last_changed)) <=

  after: sunset

To format your text as code, enter three backticks on the first line, press Enter for a new line, paste your code, press Enter again for another new line, and lastly three more backticks.

Don't forget you can edit your post rather than repeatedly posting the same thing.
