Template.yaml not loading

Configuration
1

I created a file template_test.yaml
And i reference it from the configuration.yaml file with template: !include template_test.yaml
even after multiple full restart it still wont create that sensor

in that file there is only

- sensor:  
    - name: "Test Sensor Check"
      state: "Working"
      unique_id: template_test_check

This isn’t a template. And your sensor has no event to listen for to cause an update.

What happens if you use:

state: "Working {{ now() }}"

That should update every minute.

Solved - something was messing up loading my template.yaml file - i restored backup and all was fine
