Camera still_image_url template example

Configuration
1

I’m playing with the first time with templating. Here I read:

still_image_url (Required): The URL your camera serves the image on, eg. http://192.168.1.21:2112/. Can be a template.

But even following the link to the template docs page I don’t understand how use it.
Here my (wrong) code:

camera:
  - platform: generic
    still_image_url:
      value_template: >
        {% if states.sun.sun.state == "above_horizon" %}
           "http://api.sat24.com/animated/ALPS/visual/1/Central%20European%20Standard%20Time/2380259'%20width=400%20height=291"
        {% else %}
           "http://api.sat24.com/animated/ALPS/infraPolair/1/Central%20European%20Standard%20Time/2380259'%20width=400%20height=291"

I get this error:

Failed config
  camera.generic: 
    - Invalid config for [camera.generic]: template value should be a string for dictionary value @ data['still_image_url']. Got OrderedDict(...)

What’s my mistake here?

This is a total guess…

camera:
  - platform: generic
    still_image_url: >
      {% if is_state('sun.sun' , 'above_horizon') %} http://api.sat24.com/animated/ALPS/visual/1/Central%20European%20Standard%20Time/2380259'%20width=400%20height=291
      {% else %} http://api.sat24.com/animated/ALPS/infraPolair/1/Central%20European%20Standard%20Time/2380259'%20width=400%20height=291
      {% endif %}

(edit) changed the template to use is_state, which is the preferred method.

Interesting. Hence no need for templating here. It seems something like ‘php’ that allows to print something inside an html page.
