+
+Some movement sensors and door/window sensors will apear as a switch. By using a template binary sensor, the switch can be displayed as a binary sensors. The original switch can then be hidden by [customizing.](/getting-started/customizing-devices/)

+      value_template: "{{ states.switch.movement.state == 'on' }}"
