Using the Hubble Connected for Motorola app on an Android device with Android 8.0 and later you can view the camera on your home screen.
You can activate this under the Application Settings (Tap the Menu icon and then scroll down to Application Settings and tap to select it), where it is listed under Rich Notifications.
Once activated you can get the picture-in-picture on your home screen of the camera you were viewing when you closed the app. It works irrespective of whether you use the app at home or are connected to another network.
If you no longer want to have the PIP window on your home screen, either deactivate it under the Application Settings or close the PIP window.
