Phase B kickoff — Pi hardware is wired up and posting readings to
Odoo via /fp/iot/ingest every 30 seconds. No more simulations;
this is real tank-temperature data.
New files:
- `pi/fp_iot_poller.py` — tiny systemd daemon. Reads every DS18B20
under /sys/bus/w1/devices/28-* (kernel CRC-validated) and POSTs
a batch to /fp/iot/ingest with the shared-secret token. Handles
transient network failures by logging + retrying on the next
30-second tick. Config in /etc/fp-iot/poller.conf (ODOO_URL,
INGEST_TOKEN, INTERVAL_SECONDS).
- `pi/fp-iot-poller.service` — systemd unit with hardened sandbox
(NoNewPrivileges, ProtectSystem=strict, ProtectHome, PrivateTmp,
ReadOnlyPaths=/sys/bus/w1 /etc/fp-iot). Auto-starts on boot,
restarts on failure.
- `scripts/fp_iot_setup_live_sensor.py` — one-shot entech
initialiser: rotates the ingest token to a real random secret,
picks a test tank + temperature parameter, creates the
fp.tank.sensor record for serial 28-000000b276e4 with 15-35°C
alert thresholds sized for bench testing.
Verified end-to-end: Pi reads probe → posts to Odoo → reading lands
in fp.tank.reading within 1s. 5 consecutive readings at 30s
cadence show smooth temperature trend (probe cooling from 27.25°C
to 26.06°C after being handled). in_spec flag correct, sensor
cache (last_reading_value / _at / _in_spec) updates on every
reading.
Not yet done — Phase B continued:
- Repackaged iot_drivers path (full Odoo IoT integration vs this
simple HTTP path) — this poller is the minimal viable pilot.
- Multi-probe (scalable to N probes per Pi; code already supports,
just need more hardware).
- Graduate to the proper iot.device + iot.box Odoo registration
flow.

Phase A of the IoT initiative — gets the server-side infrastructure
in place before the Raspberry Pi hardware arrives, so the iot admin
UI + /fp/iot/ingest endpoint are ready to accept the first real
temperature reading as soon as the Pi is wired up.
New top-level folder: fusion_iot/
1. **iot_base/** — Odoo S.A. iot_base module, copied from
RePackaged-Odoo verbatim. LGPL-3 upstream, no changes needed.
2. **iot/** — Odoo S.A. iot module, repackaged:
- `models/update.py` neutralised (removed the publisher_warranty
IoT-Box-counting report that phones home to odoo.com for
enterprise licence enforcement)
- `iot_handlers/lib/load_worldline_library.sh` deleted (proprietary
Worldline payment lib fetch from download.odoo.com, not needed)
- `wizard/add_iot_box.py._connect_iot_box_with_pairing_code` —
upstream called odoo.com's iot-proxy to resolve pairing codes;
replaced with a no-op. Pi-side iot_drivers proxy registers
directly with this Odoo server instead.
- Manifest rebranded with an explicit changelog preamble.
3. **fusion_plating_iot/** — new plating-specific wrapper:
- `fp.tank.sensor` — maps an iot.device (or a direct-HTTP-ingest
sensor) to a fusion.plating.tank + fusion.plating.bath.parameter.
Supports DS18B20, PT100/1000, pH, conductivity, level. Per-sensor
alert_min/max overrides.
- `fp.tank.reading` — append-only time-series. On create, evaluates
against sensor's alert range. On in-spec → out-of-spec TRANSITION,
auto-raises a fusion.plating.quality.hold (once per excursion,
no spam during sustained out-of-spec).
- `POST /fp/iot/ingest` — shared-secret HTTP endpoint for sensors
bypassing the Pi proxy. Token via X-FP-IOT-Token header OR body.
Accepts single-reading or batch payloads.
- Menu under Plating → Operations → Sensors & Readings.
- Tank form inherits get a Sensors tab inline.
Deployed to entech. Verified end-to-end:
- Install: iot_base + iot + fusion_plating_iot all 'installed'
- Smoke test: in-spec → out-of-spec → hold raised (HOLD-0010);
continued excursion → NO duplicate hold; back-in-spec → NEW
excursion → NEW hold (HOLD-0011) ✓
- HTTP endpoint: correct token → 200 accepted; wrong token → 401;
unknown device_serial → 404; batch payload → 200 accepted=N ✓
Phase B (when Raspberry Pi hardware arrives): DS18B20 iot_handler
driver for the Pi-side iot_drivers proxy + systemd service on
vanilla Raspberry Pi OS + first live reading from physical probe.
