We just bought a second home with a Ring doorbell and several cameras. Our main residence already has a Ring system. We would like to add the new system to our existing account and I have added a new location. However, we don’t have the QR codes available to add the devices and some of the cameras are inaccessible under the roof eaves. Is there a way to simply merge the old system to our account, or do I need to manually add each device to the new location I created? How can I do this if I don’t have the QR codes?
