# homeai-esp32/setup.sh — P6: ESPHome firmware for ESP32-S3-BOX-3
#
# Components:
#   - ESPHome            — firmware build + flash tool
#   - base.yaml          — shared device config
#   - voice.yaml         — Wyoming Satellite + microWakeWord
#   - display.yaml       — LVGL animated face
#   - Per-room configs   — s3-box-living-room.yaml, etc.
#
# Prerequisites:
#   - P1 (homeai-infra) — Home Assistant running
#   - P3 (homeai-voice) — Wyoming STT/TTS running (ports 10300/10301)
#   - Python 3.10+

  │  1. pip install esphome                                         │
  │  2. Create esphome/secrets.yaml (gitignored)                   │
  │  3. Create esphome/base.yaml (WiFi, API, OTA)                  │
  │  4. Create esphome/voice.yaml (Wyoming Satellite, wakeword)    │
  │  5. Create esphome/display.yaml (LVGL face, 5 states)          │
  │  6. Create esphome/animations.yaml (face state scripts)        │
  │  7. Create per-room configs (s3-box-living-room.yaml, etc.)    │
  │  8. First flash via USB: esphome run esphome/<room>.yaml       │
  │  9. Subsequent OTA: esphome upload esphome/<room>.yaml         │
  │  10. Add to Home Assistant → assign Wyoming voice pipeline     │
  │                                                                  │
  │  Quick flash (once esphome/ is ready):                          │
  │    esphome run esphome/s3-box-living-room.yaml                 │
  │    esphome logs esphome/s3-box-living-room.yaml                │
