Go to Mario’s driver channel and enroll your hub, find the Aplicaciones Virtuales Mc in the list of drivers and click the install button. Once it is installed you add the virtual calendar by using the “Add Device / Search for Nearby” in the app. The device should show up in the room that your hub is in. Configure it with your location in the settings. After you add the parent device you use that to create the virtual calendar.
