# POS-Automation — Decisions
|
||
|
||
Format: `YYYY-MM-DD: <decision> — <why>`
|
||
|
||
- **2026-06-07: On-demand trigger via MQTT bridge (lgtv pattern), not cron.** Seth
|
||
wants a Google Home button, not a scheduled print. Bridge `pos-briefing-mqtt.service`
|
||
(systemd, `User=claude`) on steel141 subscribes to `posbriefing/button/press` on
|
||
broker CT 301 (192.168.0.154); HA exposes a `script` to Google as a Scene (button).
|
||
The earlier "schedule 4:58am/3pm" was never a real cron job — that commit only
|
||
edited SESSION.md.
|
||
- **2026-06-07: Printer discovered by MAC `50:57:9c:eb:0f:07`, not a fixed IP.** The
|
||
TM-m30's IP changes on every reboot (router DHCP, no reservation). Cache last IP
|
||
(`~/.cache/pos-briefing/last_ip`), verify by MAC + port, sweep the /24 on a miss.
|
||
A router DHCP reservation would make this belt-and-suspenders but isn't required.
|
||
- **2026-06-07: Summaries on `gemma4:26b`; story selection stays on a fast model.**
|
||
Seth asked to switch summaries to gemma4. gemma4:26b under `format:json` ignores
|
||
the bare-array instruction and emits a reasoning object (`{"thought": ...}`), which
|
||
broke Phase-1 selection. Selection now uses `ollama_select_model` (default
|
||
`qwen2.5:1.5b`); summaries use `ollama_model` = `gemma4:26b`. Also better latency
|
||
for an interactive button.
|
||
- **2026-06-07: yfinance installed on steel141** via `pip --user --break-system-packages`
|
||
(PEP 668). It was missing after the CT 166 → steel141 migration — the original
|
||
"not firing" had two causes: no cron ever installed + this missing dependency.
|
||
- **2026-06-07: HA side deployed on VM HA `192.168.0.146`** (`/config/scripts.yaml`
|
||
+ `script.print_daily_briefing` in `configuration.yaml` `google_assistant.entity_config`;
|
||
backups in `/config/.backup/`). MQTT-discovery button entity id is
|
||
`button.pos_briefing_print_daily_briefing` (HA prefixes the device name). Access:
|
||
`ssh seth@192.168.0.146` (key auth), `bash -lc "ha core check|restart"`, services via
|
||
`$SUPERVISOR_TOKEN` → `http://supervisor/core/api/`. See `docs/ha-setup.md`.
|
||
- **2026-06-07: Exposed to Google as a SWITCH tile, not a Scene.** HA scripts/scenes
|
||
get Google's Scene trait, which Google Home does NOT render as a tappable tile
|
||
(voice/Routine only) — the button was invisible. A template switch
|
||
(`switch.print_daily_briefing`) tiles like the TV. **Confirmed working end-to-end
|
||
2026-06-07: a Google Home tap printed a receipt.** State is forced off and both
|
||
on/off fire the print (debounce in bridge prevents double-print) because HomeGraph
|
||
state push is down — keep this until reportState works, then simplify to on-only.
|
||
- **2026-06-07: HomeGraph SA key regenerated.** The old `/config/SERVICE_ACCOUNT.json`
|
||
key was invalid (`invalid_grant` — rotated in the lgtv 06-06 cleanup, never refreshed),
|
||
breaking requestSync/reportState. Seth issued a new JSON key for `claude@seth-freiberg.iam`
|
||
(id `8e3e812b6913…`); deployed to HA (0600), restarted. Auth now succeeds
|
||
(400→404). **Residual:** requestSync/reportState still 404 ("agent not registered in
|
||
HomeGraph") even after a Google re-sync — control (EXECUTE) works, but live state
|
||
push to Google does not yet. Non-blocking for the print button (always-off by design).
|
||
Revisit if TV/projector live state matters (may need a full unlink+relink).
|
||
- **2026-06-07: paho-mqtt v1 callbacks (`CallbackAPIVersion.VERSION1`).** paho 2.1.0
|
||
is installed for `claude`; matches the working lgtv bridge. One-time deprecation
|
||
warning at startup is harmless.
|
||
|
||
## Deferred / Rejected
|
||
- **Print latency (~1–2 min/press):** gemma4:26b summarization (+ yfinance) dominates.
|
||
Acceptable for v1; the button returns immediately and `posbriefing/status` tracks
|
||
progress. Optimize later (model keep-alive, fewer/shorter summaries) if it annoys.
|
||
- **Router DHCP reservation for the printer:** Seth's router action; MAC discovery
|
||
makes it optional. Add if convenient to drop the sweep fallback.
|
||
- **zfs/reddit/grafana dashboard fields return None on steel141** (not the tank/ZFS
|
||
host; `cannot open 'tank'`). Out of scope for the trigger work — track separately.
