What's the difference between a regular Home member, an Administrator and the Homeowner?

The Homeowner has access to all functions. Administrator has access to all functions except the ability to transfer the homeowner rights, delete the home and granting administrator rights to other members. A common member only has access to operate devices, receive notifications (alarm, moment/automation trigger, device added/removed and invite) from a home, configure device settings and schedules.
