+When using `wait_template` within an automation `trigger.entity_id` is supported for `state`, `numeric_state` and `template` triggers, see also [Available-Trigger-Data](/docs/automation/templating/#available-trigger-data).
+
+{% raw %}
+```yaml
+wait_template: "{{ is_state(trigger.entity_id, 'on') }}"
+```

+
+It is also possible to use dummy variables, e.g., in scripts, when using `wait_template`.
+
+{% raw %}
+```yaml
+# Service call, e.g. from an automation.
+service: script.do_something
+data_template:
+  dummy: "{{ input_boolean.switch }}"
+
+# Inside the script
+wait_template: "{{ is_state(dummy, 'off') }}"
+```
