Challenge 1 Hard

The Automation Architect: You want to create an automated "Scene" for a "Movie Night." List three IoT devices you would include and describe the Actuation for each.

  • Answer:
  • Smart Lights: Dimming to brightness.
  • Smart Blinds: Closing to block out external light.
  • Smart Plug (TV/Projector): Powering on the home theater system.
  • Hint: Think about the "Home SMART" features.

💡 Hint: Think about the "Home SMART" features.

Challenge 2 Hard

The Troubleshooting Logic: A user's smart light bulb works fine via a voice assistant but won't respond to the mobile app. Which layer of the 4-layer architecture is likely failing? Justify your answer.

  • Answer: The User Interface (Layer 4) is likely failing. Since the bulb responds to voice, we know the Sensor/Device, Connectivity, and Processing layers are working. The problem is specific to the "App" (the user's interface), suggesting a software bug or a sync issue with that specific interface.
  • Hint: If the "muscle" works for one "brain," the "muscle" itself isn't broken.

💡 Hint: If the "muscle" works for one "brain," the "muscle" itself isn't broken.
