+### {% linkable_title Basic Configuration %}
+
+The `netatmo` binary sensor platform is consuming the information provided by a [Netatmo Welcome](https://www.netatmo.com) camera. This component allows you to get the latest event seen by the camera.
+
+To enable the Netatmo binary sensor, you have to set up [netatmo](/components/netatmo/), this will use discovery to add your binary sensor.
+
+### {% linkable_title Advanced configuration %}
+
+If you want to select a specific sensor, set discovery to False for [netatmo](/components/netatmo/) and add the following lines to your `configuration.yaml`:
+
+```yaml
+# Example configuration.yaml entry
+binary_sensor:
+  platform: netatmo
+  home: home_name
+  cameras:
+    - camera_name1
+  monitored_conditions:
+    - Someone known
+    - Someone unknown 
+    - Motion
+```
+
+Configuration variables:
+
+- **home** (*Optional*): Will use the cameras of this home only.
+- **cameras** array (*Optional*): Cameras to use. Multiple enties allowed.
+    - 'camera_name': Name of the camera to display.
+- **monitored_conditions** array (*Optional*): List of monitored conditions.
+    - 'Someone known'
+    - 'Someone unknown'
+    - 'Motion'
+
