What’s the difference between “Create a Home” and “Share device”?
1. The "Create a Home" means creating a Home in the App first. You can add multiple devices and
members to the Home. The members in your Home can see all the devices. And any new devices
added to your Home will automatically be shared with all Home Members. For example, the
homeowner added an Air Quality Monitor in the Home at first. The other members can see it. Then
the homeowner added a Smart Plug in the Home later, the other members can see it also.
2. About the "Share Device": you should add the device to the APP first. Then you go into the device
information interface, and tap "Share Device “to share it with other users. If you added another
device to the App, and you want to share it with other users. You should repeat the sharing steps.
