+{% raw %}
+```yaml
+automation:
+  trigger:
+    platform: state
+    entity_id: device_tracker.paulus, device_tracker.anne_therese
+    to: 'home'

+  action:
+    service: lock.lock
+    entity_id: lock.my_place

+{% endraw %}
+
+The `for` template(s) will be evaluated when an entity changes as specified.

   Use quotes around your values for `from` and `to` to avoid the YAML parser interpreting values as booleans.
