Month 4 Capstone: The Fully Aware Room

This capstone ties the whole month together. You will design and build a smart room that senses its environment and responds meaningfully, combining Zigbee inputs, Home Assistant automations, smart outputs, and your Month 3 AI camera into one system. Use this as your specification and checklist, then record a short demo of your fully aware room in action.

What you have built this month

Over the month you created a genuinely advanced smart home: devices that respond to your presence, lighting that reacts to time, mood, and movement, voice-free automation powered by the AI camera, and full Zigbee integration through Home Assistant. The capstone asks you to combine these into one coherent room rather than a set of separate demos, so the pieces work together and reinforce each other.

How your project is judged

A complete capstone, the fully aware room, uses at least three different sensors or input triggers to control at least three different smart devices, all integrated into Home Assistant. It must include a Zigbee input device (a motion, button, or door sensor), a Home Assistant automation or scene, a smart output (a relay or bulb), and at least one integration with your Month 3 AI camera. The best projects combine these so the room reasons about context, for example acting only when several conditions agree.

Working through it

Requirement: three inputs. Choose at least three triggers from your kit, such as a motion sensor, a door sensor, a button, the temperature sensor, and your AI camera.

Requirement: an AI camera integration. Include at least one behavior driven by the Month 3 camera detection, connected to Home Assistant as you built in Lessons 8 and 9.

Requirement: three outputs. Control at least three devices, such as a bulb, a smart plug, a relay, or a scene, in response to your inputs.

Design context-aware automations. Combine inputs so the room reasons about the situation, for example a motion sensor that turns on a light only if the camera does not already see someone in the room.

Demonstrate it. Record a short video or an image with a description showing your triggers, the devices they control, and how the AI camera factors in, and share it.

Capstone requirements checklist

# The Fully Aware Room requires at least:
#  [ ] 3+ inputs / triggers, including one Zigbee input
#      (motion, door, or button sensor)
#  [ ] 1+ Home Assistant automation or scene
#  [ ] 3+ smart outputs (bulb, plug, relay, or scene)
#  [ ] 1+ integration with the Month 3 AI camera

# example combinations to spark ideas:
#  - motion turns on a light ONLY IF the camera sees no one already there
#  - a button activates a scene AND puts the camera into night-watch mode
#  - temperature + camera detection together control a fan and alerts

Each checkbox is a requirement; the example combinations show how to make inputs work together so the room responds to context, not just isolated events. Meeting all four is a complete project.

Common mistakes and troubleshooting

Building separate demos instead of one integrated room. Combine the inputs and outputs so they cooperate, for example gating one device on another sensor's state.

Leaving out the AI camera. At least one behavior must use the Month 3 camera detection integrated with Home Assistant.

Automations that fire at the wrong time. Add conditions (after sunset, away mode, or camera state) so actions run only when they should.

Disassembling the Pi afterward. Keep it set up; you continue using it in the cyber-security month.
