+#### {% linkable_title Template trigger %}
+
+Template triggers work by evaluating a [template] on each state change. The trigger will fire if the state change caused the template to render 'true'.
+
+```yaml
+automation:
+  trigger:
+    platform: template
+    value_template: '{% raw %}{% if is_state('device_tracker.paulus', 'home') %}true{% endif %}{% endraw %}'
+```
+
 #### {% linkable_title Time trigger %}
 
 Time can be triggered in many ways. The most common is to specify `after` and trigger at a specific point in time each day. Alternatively, you can also match if the hour, minute or second of the current time has a specific value. For example, by only setting minutes in the config to 5 it will trigger every hour when it is 5 minutes past whole.  You cannot use `after` together with hour, minute or second.
