Models: 16 status/properties dataclasses + enums + temp converters
...
src/omni_pca/models.py — adds typed parsers for the full Omni object
surface beyond the initial Zone/Unit/Area properties:
- ZoneStatus, UnitStatus, AreaStatus (live state)
- ThermostatProperties, ThermostatStatus (with omni_temp_to_celsius/_fahrenheit
via clsText.DecodeTempRaw — the scale is LINEAR, not non-linear as I'd
hypothesized: C = raw/2 - 40)
- ButtonProperties, ProgramProperties, CodeProperties, MessageProperties
- AuxSensorStatus
- AudioZoneProperties + AudioZoneStatus
- AudioSourceProperties + AudioSourceStatus
- UserSettingProperties + UserSettingStatus
Module helpers:
- IntEnums: ObjectType, SecurityMode, HvacMode, FanMode, HoldMode,
ThermostatKind, ZoneType, UserSettingKind
- OBJECT_TYPE_TO_PROPERTIES / OBJECT_TYPE_TO_STATUS dispatch tables
- omni_temp_to_celsius/_fahrenheit linear conversion (citation: clsText.cs)
42 new tests in tests/test_models_extended.py; 139 total pass.

HA custom_component scaffold (binary_sensor for zones)
...
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.

Async client + mock panel + e2e roundtrip
...
src/omni_pca/connection.py — low-level OmniConnection
- 4-step secure-session handshake (NewSession, SecureSession)
- Per-direction monotonic seq with 0xFFFF -> 1 wraparound (skips 0)
- TCP framing: read first 16-byte block, decrypt, learn length, read rest
- Reader task dispatches solicited replies to Future, unsolicited to queue
- Custom exceptions: HandshakeError, InvalidEncryptionKeyError, ProtocolError,
RequestTimeoutError
src/omni_pca/models.py — typed response objects
- SystemInformation (with model_name lookup), SystemStatus, ZoneProperties,
UnitProperties, AreaProperties — all frozen+slots dataclasses with
.parse(payload) classmethods
src/omni_pca/client.py — high-level OmniClient
- get_system_information / get_system_status / get_object_properties
- list_{zone,unit,area}_names walks via RequestProperties rel=1
- subscribe(callback) for unsolicited messages
src/omni_pca/mock_panel.py — async TCP server emulating an Omni Pro II
- Full handshake (controller side), seedable MockState
- Implements RequestSystemInformation, RequestSystemStatus,
RequestProperties (Zone/Unit/Area, both absolute and rel=1 iteration
with EOD termination); Nak for everything else
- 'omni-pca mock-panel' CLI subcommand
tests/ — 85 passed, 1 skip (live fixture)
- 23 unit tests for connection/models/client (canned-server fixtures)
- 7 unit tests for mock panel (raw protocol drive)
- 6 e2e tests: real OmniClient over real TCP to real MockPanel,
proves handshake + AES + whitening + sequencing all agree

Initial scaffold + protocol primitives
...
Project scaffold (uv, pyproject.toml CalVer 2026.5.10, ruff, pytest, mypy
strict config, MIT, README, .gitignore protecting any .pca / panel keys).
Library primitives (src/omni_pca/):
- crypto.py AES-128-ECB + per-block XOR seq pre-whitening, session-key
derivation (CK[0:11] || (CK[11:16] XOR SessionID))
- opcodes.py Byte-exact PacketType (12), v1 MessageType (104),
v2 MessageType (83), ConnectionType, ProtocolVersion
- packet.py Outer Packet dataclass with encode/decode
- message.py Inner Message + CRC-16/MODBUS, helpers for v1/v2
- pca_file.py Borland LCG XOR cipher, PcaReader, .pca + .CFG parsers
(KEY_PC01 = 0x14326573, KEY_EXPORT = 0x17569237 — fixed
from initial typo; verified via test_keys_match_decompiled)
- __main__.py CLI: 'omni-pca decode-pca <file> --field {host,port,...}'
PII opt-in via --include-pii
49 tests pass, 1 skipped (live fixture). Ruff clean.
