Home Assistant integration: voice-controlled smart home with 24/7 device management

[kovtcharov]

Summary

Deep integration with Home Assistant for AI-powered smart home control. This is a Tier 1 strategic use case — always-on, sensitive data, zero cloud cost. Power users report ~25% of daily AI assistant interactions are smart home commands.

GAIA + Home Assistant on Strix Halo = the most private, capable smart home AI ever built. No Alexa, no Google, no cloud. Multi-layered natural language commands processed entirely on-device.

Why This Is Critical

• Tier 1 use case (strategy doc): always-on + sensitive data = strongest AMD local advantage
• Voice-first (Voice-first interaction: parity between voice and text as P0 enabling technology #702): primary interaction mode at home is voice commands
• Killer demo for Halo Box: "Hey GAIA, turn kitchen lights to 50% and set bedroom to night mode"
• Better than Alexa/Google: cloud assistants have degraded since pushing AI (tool calling failures). Local AI with Home Assistant API is more reliable.
• 24/7 operation at zero cost — runs on NPU, no token consumption

Key Features

1. Home Assistant API integration — discover devices, read state, execute commands
2. Natural language multi-device commands — "turn kitchen and living room to 100%, bathroom to 5%"
3. Intent parsing for complex commands — decompose multi-step requests into individual API calls
4. Execution verification — check device state after command to confirm it worked
5. 24/7 resource monitoring — track device status, alert on anomalies
6. Smart automation — learn patterns (e.g., "you always dim lights at 10 PM"), suggest or auto-create automations
7. Voice control (Voice-first interaction: parity between voice and text as P0 enabling technology #702) — primary interface for home commands
8. Small business support — office lighting, HVAC, security cameras, access control

Integration with Other Features

• Autonomy engine (Always-on agent: heartbeat, scheduler, and event hooks (autonomy engine) #634): scheduled home automations, heartbeat checks on devices
• Voice (Voice-first interaction: parity between voice and text as P0 enabling technology #702): primary interaction mode for home control
• Memory (MemoryStore: persistent memory data layer (SQLite + FTS5) #542): learn user patterns and preferences over time
• Daily briefs (Personalized daily briefs: morning digest of email, calendar, news, and tasks #663): include home status in morning brief
• Messaging (Messaging adapters: Telegram, Discord, Slack integration #635): control home remotely via Signal/Telegram

Home Assistant Connection

Home Assistant exposes a REST API and WebSocket API on the local network. GAIA connects via:

• Long-lived access token (generated in Home Assistant UI)
• Base URL (typically http://homeassistant.local:8123)
• All communication stays on the local network — no cloud relay

Dependencies

• Always-on agent: heartbeat, scheduler, and event hooks (autonomy engine) #634 (autonomy engine — for scheduled automations)
• Voice-first interaction: parity between voice and text as P0 enabling technology #702 (voice-first — primary interface for home commands)
• MemoryStore: persistent memory data layer (SQLite + FTS5) #542 (MemoryStore — for pattern learning)

Acceptance Criteria

• Discover Home Assistant devices and their capabilities
• Execute single and multi-device commands via natural language
• Voice command support for home control
• Execution verification (confirm devices changed state)
• 24/7 device monitoring with anomaly alerts
• Pattern learning for automation suggestions
• All communication stays on local network
• Demo: "Hey GAIA, set the house to movie mode" (dims lights, turns on TV, closes blinds)
