How do I share the control of Apple HomeKit?

You can share control of HomeKit accessories with other people if they use iOS 10 or later and are signed in to iCloud.

 

To share control, you will need to be either at home or have a home hub set up in your home when sending an invite.

 

In the VELUX ACTIVE with NETATMO app locate "Settings > Home management > HomeKit > Invite"

 

In the Apple Home app locate "The "arrow icon" in the upper-left corner > Invite > Enter the person's Apple ID used with iCloud > Send Invite"
