Want to make sure Circle manages any new devices that connect to your home network? You can use the "Assign new devices to the Home profile" option!
Home Profile and New Devices
While setting up Circle Home Plus you’ll be given the option to create a Home profile for shared devices. You’ll also have the option to assign new devices to the Home profile or have them automatically set to “Unmanaged”. Make sure to set up this option and the Home profile to your liking.
Protip: you can always change Home profile’s settings later by tapping on the “house” icon on the main Circle screen. You can change the settings for auto assigning new devices to the Home profile from the “Devices” screen as well (that’s in the top right on the main Circle screen).
