Trigger troubble

Hi there.

Why does not this automatisation trigger:

- id: '1574892412940'
  alias: Nattsenking av temp
  description: Slar ned temperaturen etter klokken 00.00 til 16 grader
  trigger:
  - at: 00:18
    platform: time
  condition: []
  action:
  - data:
      hvac_mode: heat
      temperature: 16
    service: climate.set_temperature

Put 00:18 in quotes “00:18”

What makes you think it is not triggering? Maybe it is triggering but nothing happens because the automation’s action is incorrect. For example, the action calls the service climate.set_temperature but fails to specify the entity_id.
