Sensors previously only tracked alarm thresholds (alert_min/alert_max).
Missing the third piece of standard process control: the SETPOINT —
what the heater/chiller controls toward and what dashboards compare
against. Without it an operator can't tell whether 89°C is "on target"
or "barely still in spec".
Schema changes:
**fusion.plating.bath.parameter** (shop-wide default)
- New `target_value` field — the default setpoint for this parameter
across the shop (e.g. 87°C for ENP bath). Parallel to existing
target_min / target_max.
**fp.tank.sensor** (per-sensor override)
- New `target_value_override` — per-sensor override, zero = inherit
from parameter. Matches the existing override pattern for alert
thresholds so users can fine-tune per-tank without touching the
shop-wide spec.
- New `effective_target` / `effective_target_unit` computed — resolves
override → parameter default, converts to company-preferred unit.
- New `_get_setpoint()` helper for internal use.
**fp.tank.reading**
- New `deviation_from_target` — signed Δ from the sensor's effective
setpoint, in the company's preferred unit. Positive = above, negative
= below, zero if no setpoint defined.
- New `deviation_band` (selection: on/near/far/out/none) — coarse band
for fast visual scanning. `on` = within ±1° of target, `near` = ±3°,
`far` = beyond, `out` = actually out of the alarm band.
**Views**
- Sensor form: split the alerting panel into two groups — "Target
(setpoint)" on the left, "Alarm band" on the right. Makes the
distinction between "where we want to be" and "where we'd panic"
visually obvious.
- Reading list: new Δ + band columns, with decoration classes
(success/info/warning/danger) so the list reads at a glance.
- Tank form Sensors tab: inline setpoint + unit column.
Seeded: parameter "Bath Temperature (Hot Process)" now carries
target_value=87°C as a realistic ENP shop default. Sensors inherit
unless they set their own override.
Design decisions kept simple:
- Did NOT add a warning band (warn_min/warn_max). Two-tier model
(setpoint + alarm band) is enough for the pilot. Can add soft
warnings later as a separate commit if ops wants them.
- Did NOT auto-control heaters. Setpoint is stored as metadata only;
actual heater actuation via IoT is a future phase C project.
Verified: setpoint 87°C stored → displays 188.60°F on the live pilot
sensor (company pref = F). Each incoming reading correctly computes
signed deviation; bands colour the reading list appropriately.

The sensor readings list always showed raw °C regardless of the
Plating Settings Temperature Unit preference (res.company.x_fc_default_temp_uom).
On a Fahrenheit-preferred shop, a 40°C reading should render as 105°F.
Fix: add display-aware computed fields alongside the canonical ones.
**fp.tank.reading**
- `value` / `unit` renamed with "(raw)" labels — these are the stored
canonical values (always °C for temperature, because every
temperature chip reports in Celsius natively)
- `display_value` + `display_unit` computed from company pref — only
flips C→F when parameter_type='temperature' AND company pref='F';
pH/conductivity/etc pass through untouched
- `display_name` now uses display_value so it reads naturally
("Sensor — 105.58 °F @ ...") regardless of region
**fp.tank.sensor**
- Mirrored the same pattern on the cached last-reading fields
- `last_reading_display` + `last_reading_display_unit` for lists
- `last_reading_value` hidden behind group_no_one (debug-only)
**Views**
- fp.tank.reading list: show display_value/display_unit, raw value
hidden by default (toggle from column picker if needed)
- fp.tank.sensor list + form + tank inline: same pattern
- Raw value kept visible as an optional column so data engineers
can still audit canonical storage
Why store canonical: spec thresholds (alert_min/max) live on the
sensor in °C. If the same Odoo serves a multi-region company
(Canada in C, US affiliate in F), switching a single preference
flips every UI without touching data. Alert logic keeps comparing
canonical values, so out-of-spec holds fire correctly regardless
of display unit.
Verified: 40.88°C raw → 105.58°F display on the live pilot probe
with company pref='F'. All 5 recent readings tested, display
fields updated correctly on every poll.

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.
