+title: UniFi Drive
+description: UniFi Drive Widget Configuration
+---
+
+Learn more about [UniFi Drive](https://ui.com/integrations/network-storage).
+
+## Configuration
+
+Displays storage statistics from your UniFi Network Attached Storage (UNAS) device. Requires a local UniFi account with at least read privileges.
+
+Allowed fields: `["total", "used", "available", "status"]`
+
+```yaml
+widget:
+  type: unifi_drive
+  url: https://unifi.host.or.ip
+  username: your_username
+  password: your_password
+```
+
+!!! hint
+
+    If you enter incorrect credentials and receive an "API Error", you may need to recreate the container or restart the service to clear the cache.
