OmniClientV1Adapter (src/omni_pca/v1/adapter.py)
V2-shape facade over OmniClientV1. Exposes the OmniClient surface the
HA coordinator was written against — get_system_information,
list_*_names, get_object_properties (synthesized from streamed names),
get_extended_status (chunked, routed to v1 typed status opcodes),
get_object_status(AREA, ...) (derived from SystemStatus.area_alarms),
events() (EventStream on v1 SystemEvents opcode 35), plus all the
write-method shims.
Chunks unit/zone/thermostat/aux polls per-type because firmware 2.12
NAKs Request*Status with >~62 records in one shot (verified live).
Falls back to "Area 1".."Area 8" when the UploadNames stream returns
zero areas — common on panels where the installer didn't name them.
custom_components/omni_pca/coordinator.py
_ensure_connected picks OmniClientV1Adapter for transport=udp. New
_walk_properties_v1 replaces the v2 RequestProperties walk with a
name-stream + synthesized-Properties pass.
custom_components/omni_pca/config_flow.py
_probe routes to OmniClientV1Adapter for transport=udp instead of
trying to drive v2 OmniClient over UDP (which silently dropped after
handshake, per the earlier diagnosis).
src/omni_pca/events.py
parse_events / _ensure_system_events / EventStream now take an
expected_opcode arg (default v2 SystemEvents=55, v1 callers pass 35).
Word format is byte-identical between v1 and v2, so the typed-event
decoder is unchanged.
src/omni_pca/v1/client.py
_range_status supports the long-form RequestUnitStatus (BE u16
start/end) so panels with unit indices > 255 (sprinklers, flags) work.
Verified end-to-end against firmware 2.12 panel at 192.168.1.9:
config entries:
state=loaded Omni Pro II (host.docker.internal) (mock)
state=loaded Omni Pro II (192.168.1.9) (real, v1+UDP)
real-panel entities created in HA: 96 (30 binary_sensor, 26 light,
15 switch, 13 button, 9 sensor, 3 climate)
cross-check: light.omni_pro_ii_front_porch_2 = on (matches live
probe: unit #2 'FRONT PORCH' state=0x01 brightness=100)
dev/probe_v1_coordinator.py
Coordinator-shaped end-to-end smoke test against the real panel
without HA — drives the full discovery + poll cycle through the
adapter. Useful for regression-checking the v1 wire path.
dev/add_real_panel.py
Programmatically adds the real-panel config entry to the dev HA
stack via the REST config-flow endpoints. Idempotent.
custom_components/omni_pca/const.py:
+ CONF_TRANSPORT, TRANSPORT_TCP, TRANSPORT_UDP, DEFAULT_TRANSPORT='tcp'
custom_components/omni_pca/config_flow.py:
+ 'transport' field in _USER_SCHEMA with vol.In([tcp, udp]),
default tcp (so existing flows are unchanged)
+ transport stored in entry.data on create
+ reauth carries the existing transport over from entry.data
+ _probe() takes transport=, propagates to OmniClient
custom_components/omni_pca/coordinator.py:
+ transport= constructor arg, defaults to 'tcp'
+ _ensure_connected passes transport= through to OmniClient
custom_components/omni_pca/__init__.py:
+ reads transport from entry.data (default tcp), passes to coordinator
Backward-compat: existing config entries without a transport key fall
through to 'tcp', identical to current behavior. New entries get the
choice at the config-flow form. The reauth step preserves the existing
transport so users don't have to re-pick it.
357 tests pass; ruff clean across src/ tests/ custom_components/.
HA integration tests don't need updating because they don't pass
transport= explicitly (default tcp matches the mock's default).
custom_components/omni_pca/ — drop-in HA integration:
- manifest.json (HA 2026.x, iot_class=local_push, requires omni-pca lib)
- config_flow.py — host/port/controller_key with auth + reauth steps,
parse_controller_key() extracted as pure testable function
- coordinator.py — OmniDataUpdateCoordinator with long-lived OmniClient,
unsolicited push wiring, ConfigEntryAuthFailed on bad key, reconnect on err
- binary_sensor.py — one entity per named zone, zone_type -> device_class map
(OPENING/MOTION/SMOKE/etc), is_on derived from ZoneProperties.status
- const.py, strings.json, translations/en.json, README.md
- hacs.json at root for HACS distribution
tests: 97 pass + 2 skip (HA harness not installed; importorskip in
test_ha_imports.py). 12 cases for parse_controller_key validation.
Ruff clean across src/ tests/ custom_components/. Status of HA component
itself NOT validated against a running HA — needs that next.
