I have a Smart Hub at a remote home location. I have only the data, no voice. It is used to occasionally check a security camera. Twice recently, after leaving the location, three or four days later, the camera can't be accessed. When returning to the location, the hub needs to be rebooted in order to restablish the connection. This is not acceptable. Is there some sleep setting that is enabled? Something else? This is difficult to troubleshoot since the problem occurs after leaving the location and it is sometimes months before I revisit.
