Templating state_attr question

Configuration
1

Is this the right way to write this, more so the int part?

- platform: template
      value_template: "{{ state_attr('sun.sun', 'elevation') | int > -3.5 }}"

The int filter produces an integer, in other words a whole number (no fractional values: 1, 2, 3, etc).

The sun’s elevation is an attribute. In fact, because it’s an attribute, it can have a type that is something other than a string (in contrast, an entity’s state can only be a string). In this particular case, the elevation attribute is a floating-point number (a “float”). That means you don’t need to convert it using either int or float.

      value_template: "{{ state_attr('sun.sun', 'elevation') > -3.5 }}"
