 Configuration variables:
 
 - **home_mode_name**: (*Optional*): Arlo base station does not have a built-in home mode. You can map one of your custom modes to home assistant's home mode by setting the name of the custom mode in this configuration variable. The name of the custom mode should match exactly as you set it up in the Arlo app.

+These examples are based on an Arlo base station named `my_arlo_base_station`. Replace this with the name of your base station's `entity_id`.

+```yaml
+- id: arm_arlo_when_leaving
+  alias: Arm Arlo cameras when leaving
+  trigger:
+    platform: state
+    entity_id: group.family
+    from: home
+    to: not_home
+  action:
+    service: alarm_control_panel.alarm_arm_away

+Setting Arlo to a custom mode (mapped to `home_mode_name` in `configuration.yaml`) when arriving.
+
+```yaml
+- id: disarm_arlo_when_arriving
+  alias: Set Arlo cameras to Home mode when arriving
+  trigger:
+    platform: state
+    entity_id: group.family
+    from: not_home
+    to: home
+  action:
+    service: alarm_control_panel.alarm_arm_home
+    entity_id: alarm_control_panel.my_arlo_base_station

+You can also completely disarm the Arlo base station by calling the `alarm_control_panel.alarm_disarm` service, and trigger the alarm by calling the `alarm_control_panel.alarm_trigger` service.
