+[Chacon Dio devices](https://chacon.com/en/) are connected home devices that can be controlled via RF 433 MHz or Wi-Fi.
+This {% term integrations %} gives you access to the Wi-Fi connection so that Home Assistant can list your Chacon Dio devices and interact with them in real time, the same way the vendor's smartphone application does.
+
+There is currently support for the following information within Home Assistant:
+
+- Cover devices (get statuses, move up, down, stop, and move to a given percentage)
+
+## Prerequisites
+
+You will need to use the standalone app for this device to register a username and password.

+{% include integrations/config_flow.md %}
+
+## Tips
+
+You can use the [group integration](/integrations/group) to group entities as the application proposes (for example covers of the first floor).
+You can use any Cover card like the great custom [hass-shutter-card](https://github.com/Deejayfool/hass-shutter-card) to have a specific display of the covers.
