DIY Home Automation with Android Things and the Google Assistant
summary
Shows how to build a Raspberry Pi home-automation bridge running Android Things that connects to the Google Assistant via a webhook implemented as Google Cloud Functions and mirrors device state in Firebase Firestore. Describes capturing Bluetooth HCI traces to reverse‑engineer cheap Chinese RGB bulbs, implementing their write commands (service 0xff5, characteristic 0xff9), and triggering the Pi from Firestore; presents an end‑to‑end demo done in a weekend and estimated ~10× cost savings versus retail smart bulbs.
