You can invite people with an iCloud account to share control of HomeKit accessories in your home. All people in a shared home can see accessory updates and control accessories. You must be in range of your Schlage Sense Lock in order to add other iOS devices to your HomeKit home or have a home hub set up. The user you are adding does not need to be in range of the Schlage Sense Lock, but does need to have an active internet connection.
For iOS 11.2.5 or later, follow these instructions from Apple here.
