Template triggers work by evaluating a [template](/docs/configuration/templating/) on every state change for all of the recognized entities. The trigger will fire if the state change caused the template to render 'true'. This is achieved by having the template result in a true boolean expression (`{% raw %}{{ is_state('device_tracker.paulus', 'home') }}{% endraw %}`) or by having the template render 'true' (example below). Being a boolean expression the template must evaluate to false before it will fire again.
