Trigger automation with helper switch

Configuration
1

Hello guys.
I have a helper switch to block a Lux sensor. After I set that helper switch to false I would like it to trigger another automation - I can’t get that to work - what am I missing?

This is basic:

alias: Your Automation
description: ""
trigger:
  - platform: state
    entity_id:
      - your entity of the helper normally input_boolean.xxx
    to: "off"
condition: []
action:
  - service: automation.turn_on
    data: {}
    target:
      entity_id: Your automation
mode: single

Otherwise you have to give more info …
