Problem to determine how long timer is active

I need to determine how long a timer is active . I’m using automation for it but it never fires.

- id: '1551212087751'
  alias: test
  trigger:
  - hours: ''
    minutes: ''
    platform: time_pattern
    seconds: /1
  condition:
  - condition: state
    entity_id: timer.scherm_timer
    state: active
  action:
  - data:
      entity_id: input_number.scherm_test
    service: input_number.increment

Has anyone an idea what i’m doing wrong

Don’t use the automation editor for the time pattern. It removes the necessary quotes around your time pattern. Adding that should cause it to fire.

- id: '1551212087751'
  alias: test
  trigger:
  - hours: ''
    minutes: ''
    platform: time_pattern
    seconds: '/1'
  condition:
  - condition: state
    entity_id: timer.scherm_timer
    state: active
  action:
  - data:
      entity_id: input_number.scherm_test
    service: input_number.increment

Just a question… Why are you doing this? This will bog down your machine with so many triggers. What is your goal, there could be a better way.

I need the count to determine an approx position of my shutter. This code has worked untill now but broke with the introduction of the trigger type time_pattern. I had not updated my version of home assistant fo a while
