- Add ARTIK051_REF_17K row to the tested-combinations table with a
link to aminorjourney's PR.
- New 'Firmware families — a limitation' section under Part 1
explaining that descriptors are firmware-family-specific with no
runtime feature detection, so the wrong descriptor produces
half-broken sensors rather than a clean error.
- New 'Fridge (ARTIK051)' section under Per-appliance notes with the
capability table + firmware-specific observations (port 49155,
minimal /oic/res, vestigial /hass paths, collection-resource door
model vs newer per-instance-resource fridges).
- Update config-keys reference: CLASS list gains 'fridge',
OCF_PORT defaults list gains fridge=49155.
Closes#2.
Previously the cert minting script lived in local-tools/ (gitignored)
and the README pointed at a cert-only source that didn't include the
private key or upstream chain.
setup_cert.py now lives at the repo root and live-fetches both the
peer UUID (from the relevant TLS server cert subject DN) and the
full AC14K_M + upstream chain bundle (RemoteAccessCA + CECA + ROOTCA)
from a public mirror. Each fetch has an inline workaround if the
network is restricted (UUID=..., AC14K_M_CERT_BUNDLE=...,
BRAYSTORM_URL=...). Modulus-pair check catches a wrong-key mistake
before signing. bootstrap.py removed -- imported a package that was
renamed in commit 709fdf4.
Output files use neutral client.* names. README, .env.example,
docker-compose.yml, deploy.sh, and config.py updated to match.
Provenance receipts in local-tools/cert_provenance.md.
State freshness now comes from a tiered PollScheduler over the persistent
DTLS session; OBSERVE registrations are kept as an opportunistic
acceleration layer. Behaviour is identical online vs air-gapped except
for worst-case freshness latency.
Adds three modules:
- StateCache: single source of truth, source-tagged change events
- PollScheduler: hot/warm/cold + sweep tiers, write-defer past the
fetchback-revert window, per-window RTT/slow-poll tracking
- KeepaliveTask: CoAP empty-CON ping with consecutive-fail detection
driving MQTT availability
Bridge publishes per-appliance diagnostic entities (Push Active, Last
Update Source, Poll Max RTT, Slow Polls, Poll Errors, Stalest Resource
Age, Last OBSERVE Age) under HA's Diagnostic section. Tier cadences
are descriptor-declared, calibrated against measured per-firmware
ceilings (dryer ~14 req/s, oven ~8 req/s via probe_poll_rate_combined.py).
Drops HEARTBEAT_INTERVAL_S in favour of the descriptor-declared sweep
tier; PING_INTERVAL_S now consumed by KeepaliveTask inside the bridge
rather than driven from main.py.
README explains the push/poll split and what happens when the appliance
is blocked from internet.
