+The `dovado` component manages communication with the [Dovado](http://www.dovado.com/) router. Once you've setup this component, you should enable the [sensor](/components/sensor.dovado) and [notify](/components/notity.dovado) platforms to use Dovado.
+
+To add a Dovado component to your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+dovado:
+  username: YOUR_USERNAME
+  password: YOUR_PASSWORD
+```
+
+{% configuration %}
+username:

+host:

+port:

+The `dovado` notify platform allows you to send SMS from your [Dovado](http://www.dovado.com/) router, if it supports it.
+
+<p class='note'>
+You must have the [Dovado component](/components/dovado/) configured to use this notify platform.
+</p>
+
+To add the Dovado notify platform to your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+notify:
+  - platform: dovado
+```
+
+### {% linkable_title Usage %}
+
+This is a notify platform and thus can be controlled by calling the notify service [as described here](/components/notify/). It will send an SMS notification to a single phone number in the notification **target**.
+
+```yaml
+# Example automation notification entry
+automation:
+  - alias: The sun has set
+    trigger:
+      platform: sun
+      event: sunset
+    action:
+      service: notify.dovado
+      data:
+        message: 'The sun has set'
+        target: '+14151234567'
