+The output of the above script would look like the following:
+
+```
+# This script auto generates Lovelace Entity Cards
+

+  title: Alarm Control Panel
+  show_header_toggle: true
+  entities:
+    - alarm_control_panel.simplisafe

+- type: entities
+  title: Sun
+  show_header_toggle: true
+  entities:
+    - sun.sun
+      name: Sun
+      
+- type: entities
+  title: Proximity

+  entities:
+    - proximity.home
+      name: home

+
+## 2. This script auto generates Lovelace Entity-Filter Card for your Device Trackers
+
+```

+  entities:
+{%- for e in states[item] %}
+    - {{ e.entity_id }}
+{%- endfor %}
+{% endfor %}
+```
+The output of above would look something like:
+
+```

+  card:
+    type: glance
+    title: My Device Trackers
