Room-Assistant (Bluetooth Presence) - WORKING! ✅

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

Hardware

• Pi 1: livingroom-pi (192.168.0.95)
• Bluetooth MAC: B8:27:EB:50:C9:40
• SSH: admin / 41945549
• SSH Key: ~/.ssh/id_ed25519 (Windows SSH quirk - needs manual workarounds)

Phone Tracking

• Corey's Phone: B0:C2:C7:07:28:B4 (motorola razr 2024)
• Phone MAC Discovery:
  • iPhone: Settings → About → Bluetooth
  • Android: Settings → About Phone → Status → Bluetooth address

Room-Assistant Config (/home/admin/config/local.yml)

mqtt:
  host: "192.168.0.39"
  port: 1883
  username: "corey"
  password: "41945549"

Home Assistant Entities Created

• sensor.livingroom_cluster_size
• sensor.livingroom_cluster_leader
• device_tracker.livingroom_phone (when phone in range)

Key Config Notes

• Config location: /home/admin/config/local.yml (NOT in room-assistant subdir)
• Config format: keys at root level (v2.x), no "global." prefix
• mdns module needed: sudo npm install -g mdns (for cluster discovery)
• RSSI threshold: -70 (adjustable for range)

Current Tasks

High Priority

• Entity cleanup (972 devices in spreadsheet)
• Fix hallway sensor battery (1%)
• Add Kathy's phone to room-assistant config

In Progress

• Room-assistant setup and working
• Phone MAC paired and tracking
• Multi-Pi expansion (clone SD after first Pi stable)

---

Setup Workflow (for future Pis)

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

---

Files Created

• room-assistant-config.yml — BLE presence config template
• setup-room-assistant.sh — Automated Pi setup script
• ROOM_ASSISTANT_SETUP.md — Complete setup documentation
• temp/write_ha_names.py — Push entity changes back to HA

---

Integration Points

• HA REST API (native)
• MQTT (for room-assistant)
• Mission Control dashboard (for display)
• Discord notifications (alerts)
