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.
