## Home Assistant Skill Created
- Built `skills/home-assistant/SKILL.md` with REST API documentation
- Created helper scripts (`scripts/ha-api.sh`) for quick commands
- Added references with common command examples

## Network Architecture Discovery
- Clawdbot runs through Google Cloud infrastructure (exit IP: 216.73.144.16)
- Tested firewall blocking from Corey's PC - blocks visibility but not actual connectivity
- **Privacy note**: HA entity states pass through Google's infrastructure during API calls
- Local tailnet access (192.168.0.39) works directly; external APIs route through cloud

## HA Sensor Audit
- **Total sensors found**: ~300 entities
- Categories: environmental, energy monitors, device trackers, presence, lights, air purifiers, thermostats, media, utility, security

## Battery Status Check (Door/Motion Sensors)
- **CRITICAL**: `sensor.hue_motion_sensor_3_battery` (Master Hallway) at **1%**
- Front Door (Ring): 100%
- Hue Motion Sensor 2 (Kitchen): 100%
- Guest Bath Motion: 91%
- Office Motion: 76%
- Motion Sensor Battery state: unavailable (broken entity)
- Entity names to verify: pantry_door, garage_entrance_door, office_door, master_closet_door, shower_door, master_bath_motion, master_pooper

## Frigate Fix (NVIDIA GPU Decoder)
- Problem: `Cannot load libnvcuvid.so.1`, Frigate cameras crashing
- Root cause: Missing NVIDIA decode library for TensorRT
- Attempted fix: Install `libnvidia-decode-580-server` package, rebooted
- Status: **STILL BROKEN** - Will start fresh installation tomorrow

## Voice Assistant - Local AI Replacement for Alexa
- **Stack working:**
  - Wake Word: HA Voice Preview Edition built-in
  - STT: Whisper (local, verify not cloud)
  - LLM: Ollama + minimax-m2.1 (270b parameters, local)
  - TTS: Needs Piper or Qwen3-TTS (currently cloud TTS - slow)
  - Control: Lights, climate, media all working

- **System Prompt** (for Ollama conversation agent):
```
You are a helpful smart home assistant for a Home Assistant installation.
- Control smart home devices (lights, climate, media, etc.)
- Keep responses SHORT — 1-2 sentences for voice
- Confirm actions: "Turned on the living room lights"
- Don't discuss pricing or external products
```

- **Optimization needed:**
  - STT latency (Whisper model size - try 'base' model for speed)
  - Switch TTS to local Piper or Qwen3-TTS

## Room Presence with Pi Zeros (Bluetooth Tracking)
- **Project files created:**
  - `room-assistant-config.yml` - Base config template
  - `setup-room-assistant.sh` - Automated install script
  - `ROOM_ASSISTANT_SETUP.md` - Full documentation

- **What it does:**
  - Pi Zero W BLE scans for known phones
  - Reports to HA via MQTT
  - Creates device_tracker entities per room
  - Multi-Pi setup gives room-level presence

- **Setup workflow:**
  1. Flash Pi OS Lite to SD card
  2. Enable SSH + WiFi via Pi Imager
  3. Copy config files to Pi
  4. Run `sudo ./setup-room-assistant.sh`
  5. Script prompts for: room name, MQTT creds, phone MACs

- **Phone MAC discovery:**
  - iPhone: Settings → About → Bluetooth
  - Android: Settings → About Phone → Status → Bluetooth address

- **Key config values:**
  - `rssiThreshold: -70` (adjust closer/farther detection)
  - `trackOnlyKnown: true` (only tracks listed devices)

## Brave Search API
- API Key: BSAVjWnVKGI5ZeU-mEBirztyCDmHhcI (Corey's account)
- Configured via system environment variable (needs Clawdbot restart)
- Used for web research when needed

## Action Items
- Replace battery in Master Hallway motion sensor (1% level) - remind Corey when heading home
- Verify Whisper STT is local (not cloud) for voice assistant
- Add Piper or Qwen3-TTS for local TTS (faster voice response)
- Flash Pi SD cards for room presence project
- Find phone MAC addresses for room-assistant config

## Files Created This Session
- `skills/home-assistant/` - HA skill documentation
- `skills/home-assistant/scripts/ha-api.sh` - API helper script
- `skills/home-assistant/references/commands.md` - Quick reference
- `openwakeword-mqtt.py` - Openwakeword to MQTT publisher (not needed with VPE)
- `room-assistant-config.yml` - BLE presence config template
- `setup-room-assistant.sh` - Automated Pi setup script
- `ROOM_ASSISTANT_SETUP.md` - Complete setup documentation
