Phase B of the program viewer. Three websocket commands and a stub
side-panel registration wire the HA integration to consume the
program_renderer library.
Websocket commands (all namespaced ``omni_pca/programs/``):
* ``list`` — paginated, filterable summaries. Filters: trigger_types
(TIMED / EVENT / YEARLY / WHEN / AT / EVERY), references_entity
(e.g. ``"unit:7"``), case-insensitive substring search. Each row
carries summary tokens + a flat ``references`` list for filter UI.
* ``get`` — full structured-English detail for a slot. Clausal
chains return as one logical unit even when the user clicked an
interior slot.
* ``fire`` — sends ``Command.EXECUTE_PROGRAM`` over the wire so the
panel runs the program now. Returns ``{slot, fired: true}`` on
success or a structured error.
Token serialisation uses short keys (k/t/ek/ei/s) for compact wire
format — the panel's 1500-slot table on a busy install fits in a few
hundred KB of JSON.
Coordinator-backed resolvers:
* ``_CoordinatorNameResolver`` — pulls names from data.zones / units /
areas / thermostats / buttons (HA-side ZoneProperties etc.)
* ``_CoordinatorStateResolver`` — pulls live state from *_status maps
so every websocket call sees the freshest available overlay without
round-tripping the panel. SECURE / NOT READY / BYPASSED for zones,
OFF / ON / ON 60% for units, Day / Night / Away for areas,
°F for thermostats.
Side-panel registration: ``async_register_side_panel`` registers a
custom panel under ``Omni Programs`` in HA's sidebar with a
``mdi:script-text-outline`` icon. Bundle is served at
``/api/omni_pca/panel.js`` via a static-path registration. A
working stub panel.js ships now so the wiring is exercisable;
Phase C will drop the real Lit/TS bundle into the same path.
Panel registration is wrapped in a try/except + a once-per-HA-boot
guard so test environments without ``hass_frontend`` installed don't
break the rest of the integration. The manifest only lists ``http``
and ``websocket_api`` as hard dependencies for the same reason —
panel_custom is opportunistic.
10 new HA-integration tests cover list/get/fire end-to-end plus
filters, pagination, search, live-state overlay, and structured-error
returns for bad entry_id / missing slot.
Full suite: 634 passed, 1 skipped (up from 624).
SetupData side (clsHAC.cs:3020-3038): five contiguous bool[8] arrays
immediately after ExitDelay carry per-area config flags. Offsets:
1787..1794: EntryChime
1795..1802: QuickArm
1803..1810: AutoBypass
1811..1818: AllOnForAlarm
1819..1826: TroubleBeep
Verified against live fixture: area 1 shows real homeowner choices
(QuickArm + AllOnForAlarm enabled, others off), unused areas 2-8 carry
the panel defaults (EntryChime/AutoBypass/TroubleBeep on by default).
PerimeterChime and AudibleExitDelay aren't in this contiguous block —
they live past FlashLightNum, HouseCodes flags, and 6 TimeClock
When-structs. Deferred.
New PcaAccount fields:
area_entry_chime, area_quick_arm, area_auto_bypass,
area_all_on_for_alarm, area_trouble_beep — all dict[int, bool].
MockAreaState gains the same five fields. They aren't carried in the
Properties reply on the wire (the OL2 message format doesn't have
them), so they live on MockState for snapshots and any future
SetupData-aware code, but don't surface through HA discovery yet.
v2 client list_area_names fallback: when the Properties walk turns up
no named areas (common — most homes don't name them), synthesize
"Area 1".."Area 8" so HA's _discover_areas has slots to walk.
Mirrors the v1 adapter behaviour exactly.
Knock-on win in the live-fixture HA test: area 1 now reaches
coordinator.data.areas with its configured 60s/90s delays from
SetupData, end-to-end through .pca → MockState → wire Properties →
HA's AreaProperties parser.
Full suite: 499 passed, 1 skipped.
Three more SetupData fields, varying in difficulty:
* Entry/exit delays per area — in the user section, behind 280 bytes
of Phone[8] config and 1386 bytes of Codes[99]. Derived offsets by
counting fixed-width fields out from Seek(1): EntryDelay[1..8] at
offset 1771, ExitDelay[1..8] at 1779. Verified against live fixture
(area 1: entry=60s, exit=90s; unused areas: 15s/15s panel defaults).
* TempFormat at installer offset 2993 — single byte, enuTempFormat
(1=F, 2=C). Live fixture = 1 (US install).
* NumAreasUsed at installer offset 3034 — count of installer-enabled
security areas. Live fixture = 1 (single-area home).
PcaAccount now carries area_entry_delays, area_exit_delays, temp_format,
num_areas_used. MockAreaState gains entry_delay/exit_delay/enabled
fields; mock _build_area_properties serves the configured values
(was hardcoded 60/30/Enabled).
MockState.from_pca now synthesizes per-area MockAreaState entries
for the union of named areas + (1..num_areas_used), filling in delays
and enabled flag. This means a single-area install with no
user-assigned name still surfaces area 1 with the correct config —
matching what an installer would see in PC Access.
(HA's coordinator only enumerates named areas via list_area_names,
so the area properties don't yet reach the diagnostic surface for
unnamed-but-in-use areas. That's a separate filter to revisit; the
data flow through pca_file → MockState → wire Properties reply is
already correct.)
Full suite: 499 passed, 1 skipped.
Walks the OMNI_PRO_II installer section past ZoneType, DCM stuff,
thermostat config, and the X10/VoltOut/FlagOut/ExpEnc area-group
arrays to land on the 176-byte Zones[].Area block at offset 3106.
The path from instSetupStart (2560) to zone area:
ZoneType[176] → DCM phones/accounts/type/test(5-byte clsWhen) →
DCMAlarmCode[176] → 8 DCM bytes → TempFormat..NumAreasUsed (29 bytes
of misc config including 25-byte CallBackNumber) → X10 area groups
(16) → VoltOut (8) → FlagOut (15) → ExpEnc (32) → Zones[].Area (176).
Total preamble within installer section = 546 bytes. Verified against
the live fixture: 176 zones all assigned to area 1 (single-area
install), matches expectation.
PcaAccount.zone_areas now carries {slot: area_number}; MockState.from_pca
threads it through MockZoneState.area; mock _build_zone_properties already
serves it. End-to-end test verifies the area flows through to
coordinator.data.zones[*].area.
This was the largest single-RE jump in SetupData decoding so far — got
us past the variable-length DCM block by counting fixed-width fields
out from the known ZoneType end. The clsWhen=5-byte struct was the
last unknown; derived from clsHardwareArray.ReadWhen (clsHardwareArray
.cs:456-468).
Full suite: 499 passed, 1 skipped.
SetupData (3840 bytes) holds the panel's per-object property tables.
Layout for OMNI_PRO_II's installer section (Seek to instSetupStart=2560
in clsHAC._ParseSetupData at clsHAC.cs:3156):
offset 2560: HouseCode (1 byte)
offsets 2561..2569: OutputType[0..8] (9 bytes; numVoltOutputs)
offset 2570: ZoneExpansions (1 byte)
offset 2571: NumExpEnc (1 byte)
offsets 2572..2747: ZoneType[1..176] (176 bytes; raw enuZoneType per zone)
Verified against the live fixture: 2 EntryExit + 4 Perimeter + 3 AwayInt
+ 1 Extended_Range_OutdoorTemp + 166 Auxiliary (panel default for
unused slots) — matches the named-zones cross-reference exactly.
PcaAccount gains a zone_types dict (1-based slot → raw byte). The
walker stashes the SetupData blob to a buffer up front and indexes
in by offset rather than chasing the sequential parser through all
of telephony/codes/areas — that's a bigger RE pass for another day.
MockZoneState now carries zone_type and area fields. MockState.from_pca
threads acct.zone_types through, and _build_zone_properties uses the
real value instead of hardcoded 0 (EntryExit). End-to-end against
MockPanel.from_pca: HA's discovery now classifies binary vs. analog
zones correctly straight from the .pca — outdoor temp zone surfaces
as a temperature sensor entity, motion sensors as binary_sensor,
door zones as the right kind of binary_sensor.
Full suite: 499 passed, 1 skipped. RE notes in pca_file.py.
The Names block (between SetupData and Voices) was previously walked
as opaque bytes. It's actually a sequence of seven object-family
tables, each storing N × String8(L) per the
clsAbstractNamedItem.ReadName / clsPcaCryptFileStream.ReadString8(out S, byte L)
pattern. Per-slot layout is [1 byte actual length][L bytes name],
with length 0 meaning "unused".
New PcaAccount fields:
* zone_names, unit_names, button_names, code_names,
thermostat_names, area_names, message_names
— each is {1-based slot: name}, only non-empty slots.
Object *properties* (zone_type, area_membership, etc.) aren't
extracted yet — those live in SetupData, which remains opaque.
Names alone unlock the biggest win: meaningful entity labels in
HA from a .pca snapshot.
MockState.from_pca now seeds zones/units/areas/thermostats/buttons
with MockZoneState/MockUnitState/etc. instances carrying just the
name. Defaults handle everything else. A connected client sees the
real panel's names through normal wire discovery (UploadNames
streams them back, properties synth fills the rest).
New end-to-end test verifies the HA integration discovers all 16
zones, 44 units, 16 buttons, 2 thermostats from the live fixture
when the MockPanel is built via MockState.from_pca — proving the
full file → mock → wire → HA pipeline.
Live fixture: 16 zones, 44 units, 16 buttons, 8 codes, 2 thermostats,
0 areas, 8 messages, 330 programs. (Areas in this v1 install have
no user-assigned names — expected.)
Full suite: 499 passed, 1 skipped (fixture-gated).
Adds CONF_PCA_PATH + CONF_PCA_KEY config-flow fields. When set, the
coordinator parses programs from the .pca file at that path instead
of streaming them over the wire on every entry refresh. Useful for:
* deployments where wire enumeration is slow (1500-slot iteration)
* offline snapshots when the panel is unreachable
* deterministic test setups against a known fixture
The config-flow validates the file is readable and decrypts cleanly,
surfacing pca_not_found / pca_decode_failed errors via the strings/
en.json translations.
The .pca path is checked first in _discover_programs; if absent the
wire path runs as before. So existing deployments are unaffected.
Tests cover the success path (live fixture, 330 programs) and the
two validation failures (missing file, garbage bytes).
Coordinator's _discover_programs is no longer a placeholder. It now
drives client.iter_programs() (v2 path) or the v1 adapter's forward
to OmniClientV1.iter_programs (v1 path), populating OmniData.programs
with decoded Program records keyed by slot. Errors are logged and
swallowed so partial enumeration doesn't break entry setup —
programs are non-critical telemetry.
OmniData.programs is now dict[int, Program] rather than the
ProgramProperties dict that was an empty placeholder. The
ProgramProperties dataclass remains in models.py for the Properties
opcode reply path; only the coordinator's value type changed.
New OmniProgramsSensor on the sensor platform: a single diagnostic
entity per panel whose state is the count of defined programs and
whose 'programs' attribute lists each program's slot, type name,
and schedule fields. Easy to consume from automations and the
developer-states UI.
Mock fixture seeds three programs (TIMED+TIMED+EVENT at slots 12 /
42 / 99). New integration test verifies the sensor enumerates them
in slot-ascending order with the expected per-record fields.
Full suite: 494 passed, 1 skipped (fixture-gated).
Pytest harness (in-process HA + MockPanel)
==========================================
pyproject.toml — bumps requires-python to 3.14.2 to align with HA 2026.5.x
which is what pytest-homeassistant-custom-component pins. Dev group 'ha'
pulls the harness; .python-version updated to 3.14.
src/omni_pca/mock_panel.py — Thermostat (6) and Button (3) RequestProperties
handlers added (previous commit). Without these the HA coordinator's
discovery walk produced empty thermostat/button dicts.
custom_components/omni_pca/services.py — fix CONF_ENTRY_ID import: HA
exports it as ATTR_CONFIG_ENTRY_ID, not CONF_ENTRY_ID. Aliased on import.
tests/conftest.py — re-enables sockets globally (the HA harness installs
pytest_socket which otherwise blocks our network e2e tests).
tests/ha_integration/ — new directory with full HA boot harness:
conftest.py:
- autouse enable_custom_integrations so HA loads our component
- autouse expected_lingering_tasks=True (background event listener)
- autouse _short_scan_interval (1s instead of 30s for fast tests)
- panel fixture: MockPanel on a random localhost port for each test
- configured_panel fixture: builds a MockConfigEntry, runs setup,
yields, then unloads on teardown so the coordinator's reader task
and OmniClient socket close cleanly (otherwise verify_cleanup hangs)
test_setup.py — 12 tests:
- integration loads + system_info populated
- alarm_control_panel/light/switch/climate/button/event/binary_sensor
entities materialise per platform
- unload_entry tears down cleanly
- turning a light on via HA service updates the mock state
- arming via HA service with the right code transitions the area
- arming with wrong code keeps the area disarmed and surfaces error
Total: 351 passed, 1 skipped (PCA fixture). Ruff clean across src/ tests/
custom_components/. The 12 HA integration tests run in <1s end-to-end —
they boot HA in-process, drive the config flow, exercise services, and
verify state mutations on the mock side.
Docker dev stack (manual smoke / screenshots)
=============================================
dev/docker-compose.yml — HA 2026.5 container + MockPanel sidecar.
dev/run_mock_panel.py — long-running mock with a populated state
(5 zones, 4 units, 2 areas, 2 thermostats, 3 buttons, codes 1234/5678).
dev/Makefile — make dev-up / dev-logs / dev-down / dev-mock / dev-reset.
dev/README.md — onboarding walkthrough (host=host.docker.internal,
port=14369, controller_key=000102030405060708090a0b0c0d0e0f).
.gitignore — adds ha-config/ so the persisted HA state from the dev
stack doesn't get committed.
