Replace the breadth/silence downgrade heuristic with a simpler rule: a
still-live OBSERVE session is never torn down on a sweep/cache mismatch
(the 30s sweep already corrects the cache regardless of mode) -- only a
proven reconnect invalidates subscriptions. A mismatch instead triggers
extra hot/warm subpolls this cycle as a bounded fallback.
Also stop treating a summary-poll block-level ACK timeout as session
death: distinguish TimeoutError (transfer was progressing, session
likely alive) from ConnectionError (session actually closed), backed by
a consecutive-timeout counter so a genuinely dead channel still
recovers. This was causing a flaky/slow device (e.g. a dishwasher) to
flap observe<->poll every ~45s on nothing but a slow blockwise GET.
Also remove the dead is_active/active_when scaffolding (never wired
into the coordinator) and add DEBUG logging for each OBSERVE notify
received, including its href.
The DTLS/CoAP transport code that made "ocf" an accurate name moved out to
the smartthings-local package. What's left here (capability.py, entities.py,
discovery.py, adapter.py, identity.py, capabilities/, by_type/, plus the
/device/0 batch parser) is entirely the device capability registry, so name
the package for what it does.
Flattened the redundant ocf/registry/ nesting into a single top-level
registry/ package and updated every import across the platform modules and
test suite accordingly. Verified: full test suite (80/80) passes, and the
Docker dev container reconnects to both live appliances and rediscovers
their entities cleanly after the rename.
Samsung appliances silently drop CoAP requests when hit faster than their
firmware ceiling (~8–14 req/s measured; dishwasher unknown). Multi-block
Block2 fetches on LAN hit ~100 req/s instantaneously, causing the observed
burst timeouts on block 4 and block 10 of /device/0.
Adds rate_limit_rps (default 5 req/s / 200 ms) to DtlsCoapSession with a
pace() method that enforces the inter-block delay via _stop.wait() so session
teardown interrupts the sleep cleanly. Coordinator calls pace() between hrefs
in _poll_hrefs_blocking. Also adds device IP to all GET log lines for easier
per-device filtering.
Makes the integration fully self-contained for HACS distribution.
Users installing via HACS get everything in one directory; no external
samsung_appliance package needed.
All component imports updated to relative (.ocf.*); all test imports
updated to custom_components.localthings.ocf.*. ocf_root_ca.pem moves
with the package and resolves correctly via Path(__file__).parent.
- Make href Optional[str] = None for pattern capabilities
- Remove observe field (v2 architecture observes all hrefs)
- Add rt_filter, match_fn, key_fn fields to Capability
- Add entities default value tuple[()] to Capability
- Add key_override field to BoundEntity
- Update _key() to use key_override when present
- Update _make_observe_paths() to observe all unique hrefs (OBSERVE as accelerator)
- Guard _build() to skip pattern capabilities (href is None)
- Add test_bound_entity_key_override_takes_precedence test
- Update test_capability_defaults to remove observe assertion
All 61 tests passing (60 existing + 1 new).
OCF rt is a schema category shared by many unrelated resources.
The stable unique resource address is the href. Update Capability,
discovery, common capabilities, tests, and plan accordingly.
