+
+The `wake_on_lan` (WOL) switch allows you to turn on a [WOL](https://en.wikipedia.org/wiki/Wake-on-LAN) enabled computer.
+
+<p class='note warning'>
+The WOL switch can only turn on your computer and monitor the state. There is no universal way to turn off a computer remotely.
+</p>
+
+To enable this switch in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yml entry
+switch:
+  platform: wake_on_lan
+  name: "WOL"
+  host: "192.168.1.1"
+  mac_address: "00-01-02-03-04-05"
+```
+
+Configuration variables:
+
+- **name** (*Optional*): The name of the switch. Default is 'Wake on LAN'.
+- **host** (*Optional*): The IP address or hostname to check the state of the device (on/off).
+- **mac_address** (*Required*): MAC address to send the wake up command to.
