Good question, @Minervino! The Ring app is designed to provide the quickest access to all of your Ring devices and locations. When owning Ring devices at multiple locations, all locations can be conveniently monitored and controlled through one app, and under one Ring account.
If you’ve used a different account to setup devices at another location, simply choose which account you prefer to keep and proceed to consolidate the devices. This is best done by removing the Ring devices from the account you do not plan on keeping, then setting them up again while signed into the preferred account. Once complete, all of your devices should be setup under the same owner account, and each location will be accessible through the Ring app menu. During setup, the Ring app will ask you to confirm your location, and will automatically organize your Ring devices this way. I hope this helps!
