Study Notes

SHAS System

SHAS system comprises nine core processes: user registration, guest access management, device control and monitoring, manage alerts, monitor surveillance, optimize energy usage, energy management, voice and remote control, automate scheduling, automation rules, data privacy and security, maintenance and troubleshooting.
SHAS interacts with five external actors: homeowner, service provider, guest, central hub, and system administrator.

Guest Access Management Use Case

The homeowner grants limited access to specific devices for a specific period.
Homeowner logs into the smart home app and selects "Guest Access Management."
Homeowner enters guest details and selects devices for access.
The system generates temporary access credentials and sends them via email.
Guests use credentials to log into the app and access devices.
System automatically revokes credentials after the access period expires.
If access is attempted after expiration, the system denies access and notifies the homeowner.

Device Control and Monitoring Use Case

Allows homeowners to control and monitor smart devices through the app.
Homeowner logs in and selects a device to control.
Homeowner issues a command to control the device.
System updates the device's status and notifies the homeowner.
If the system fails to connect to the device, it alerts the homeowner.

Automation Rules and Schedules Use Case

Allows homeowners to set up automation rules and schedules based on time or sensor data.
Homeowner creates a new rule with specific conditions and actions.
Central Hub monitors sensor data and applies rules when conditions are met.
The system sends a notification to the homeowner when a rule is activated.
System detects and alerts the homeowner for conflicting rules, device faults, and unexpected rule activations.

Activity Diagrams

Guest Access Management: The flow begins with the guest requesting access, then the system notifies the homeowner. If approved, the system grants access to the guest. If denied, the system notifies the guest. The flow ends with the guest either controlling permitted devices or losing access after the timeframe.
Device Control and Monitoring: The flow begins with the owner logging into the app and issuing a command. The app then sends the command to the system, which executes it on the device. The system confirms the action to the app, and the app updates the status to the owner. If the system fails to connect to the device, the app alerts the owner.
