Prior to deleting a SmartShade from the app, ensure that you remove it from any Groups or Routines that it belongs to. In addition, you need to be on the same WiFi network as the SmartBridge its paired with.
To delete a SmartShade that's paired to a SmartBridge from the app, follow these simple steps:
From the main dashboard, tap and hold the SmartShade you would like to delete.
In the pop-up that appears, tap "Delete" to remove the SmartShade.
Note that any other user accounts connected to this SmartBridge will also lose access to the deleted SmartShade.
