πŸ“‹ Protocols
New Node Commissioning
  • Same session: USB, Streamlit, this dashboard
  • Banner first, then capture the BLE MAC
  • Add the node_id to AUS_NODES and redeploy Pages
  • Bench 010 stays on hvac_telemetry_bench
  • Full procedure: docs/NODE_COMMISSIONING.md
Initial Flash (USB)
  • Physical USB-C to node
  • PlatformIO upload via Cursor / CLI
  • Sets FW_VERSION in NVS
  • Bench 010 still needs USB β†’ v4.5.16. N2 is on v4.5.16
EquiSync RF Learning
  • Hold GPIO35 at power-on β†’ learn mode
  • BLE advertisement from remote
  • Stored in NVS
  • simulate_ble_capture.py for bench test
OTA Update
  • Merge β†’ CI runs ota_ci_check.py
  • fleet_preflight_audit.py before trigger
  • Node-specific MQTT topic, no retain
  • Confirm via session_init
HIL Bench (010)
  • Site EQBNTV, table hvac_telemetry_bench
  • equisim_gauntlet.py β€” scenarios 1–68
  • Validate watermark β‰₯ 2048
  • USB flash needed β†’ v4.5.16
5-Party Ballot
  • Required: any threshold, pin, state-edge change
  • Open questions only β€” no A/B/C options
  • All 5 parties respond before merge
  • Label: needs-ballot
  • After merge: update AI.md + docs/TEN_COMMANDMENTS.md
Commit Rules
  • Every main.cpp commit β†’ bump FW_VERSION
  • kOffTroughRiseF = 1.2Β°F β€” Tier 3 to change
  • Node-specific OTA only, never fleet topic
  • static_assert(ota_status_t ≀ 512B)
  • otaWorker stack β‰₯ 12288
  • Post-ballot: update AI.md + TEN_COMMANDMENTS.md same session

Change health check notification time β€” rogue droplet cron fires at 12 PM CDT. Run crontab -l + systemctl list-timers, reschedule to 6 AM CDT (11:00 UTC). Set up email on the morning GitHub Actions brief.

USB flash N2 β†’ v4.5.16 β€” AUS001-N2 banner confirmed v4.5.16-0c660b81 and entry 0x40080638. OTA-capable. BLE MAC a4:c1:38:9f:4b:78.

USB flash bench 010 β†’ v4.5.16 β€” HIL bench is behind the field image. USB flash only. Reads stay on hvac_telemetry_bench.

Task D: fleet_baseline.json workflow β€” ballot pending β€” YAML written, not yet committed. Manual dispatch would update one existing node entry and commit. Waiting on a 5-party ballot before adding .github/workflows/.

Update fleet_baseline.json β€” approved Austin baseline still lags the image running in the field. No hardcoded versions in static docs. The Task D workflow is the intended update path.

Pages dashboard deployed β€” static HTML is on Cloudflare Pages at equilibrium-dashboard-98s.pages.dev. Custom domain still needs the CNAME above.

Doc consolidation β€” AI.md and docs/TEN_COMMANDMENTS.md are the onboarding pair. CLAUDE.md, .cursorrules, and SESSION_QUICKSTART.md are stubs.
