-```yaml
+* [Binary Sensor](/components/binary_sensor/)
-homeassistant:
+* [Cover](/components/cover/)
-  customize:
-    - entity_id: sensor
-      icon: mdi:kettle # Give all sensor the kettle icon
-    - entity_id: light.family*
-      hidden: true # Hide all lights that have an ID starting with 'family'
-    - entity_id: switch.wemo_switch_1,switch.wemo_switch_2,switch.wemo_switch_3
-      entity_picture: /local/toaster.jpg # Set picture on multiple devices
-```
