Sorry for my late response. Thank you for all of your patience while waiting for a reply. I just wanted to make sure that your issue is addressed. I can definitely understand how frustrating your situation must be. I would love to help you find a solution to this issue. I am afraid that this is not a possibility. You will need to physically be present to install these cameras and add them to your vacation home as a Home/Structure in the app.
Please let me know if you need further assistance.
