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
