83d85a9885 HA Phase C: services + diagnostics + README polish
custom_components/omni_pca/services.yaml — declares 7 services with
config_entry selectors so HA's UI gives users a panel picker:
  bypass_zone, restore_zone, execute_program, show_message,
  clear_message, acknowledge_alerts, send_command (raw escape hatch)

custom_components/omni_pca/services.py — async handlers wired via
async_setup_services on entry setup; idempotent across multiple entries.
Each handler validates entry_id, looks up the right coordinator, calls
the matching OmniClient method. CommandFailedError wrapped to
HomeAssistantError; unknown Command codes raise ServiceValidationError.
async_unload_services removes them when the last entry unloads.

custom_components/omni_pca/diagnostics.py — async_get_config_entry_
diagnostics dumps a redacted snapshot for bug reports: panel model +
firmware, discovered/live counts per object type, sha256-hashed zone/
unit/area names (so uniqueness is visible without leaking PII), last
event class, controller key REDACTED via async_redact_data.

custom_components/omni_pca/__init__.py — wires async_setup_services on
entry setup and async_unload_services on the last entry unload.

custom_components/omni_pca/README.md — full entity table, service list,
example automation, troubleshooting section, link to JOURNEY.md.

Top-level README — entity rundown updated to reflect the full v1.0
surface (was: 'binary_sensor for zones').

331 tests still pass; ruff clean across src/ tests/ custom_components/.
hacs.json already in place from initial scaffold.

57b8aa4b04 HA Phase B: alarm + light + switch + climate + sensor + button + event
custom_components/omni_pca/ — six new platform modules wrapping the
v1.0 client surface. Every command method catches CommandFailedError
and re-raises HomeAssistantError so panel rejections (bad code, etc.)
become user-friendly HA errors instead of silent failures.

alarm_control_panel.py — OmniAreaAlarmPanel per discovered area.
  Supports ARM_HOME (Day) / ARM_NIGHT / ARM_AWAY / ARM_VACATION /
  ARM_CUSTOM_BYPASS (Day-Instant). State derives from area_status via
  pure helpers.security_mode_to_alarm_state which handles arming-in-
  progress, entry/exit timers, and active-alarm overrides.

light.py — OmniUnitLight per discovered unit (every unit; non-dimmable
  units silently ignore brightness, no harm done). Brightness conversion
  via helpers.omni_state_to_ha_brightness / ha_brightness_to_omni_percent
  (Omni state byte: 0=off, 1=on, 100..200=brightness percent).

switch.py — OmniZoneBypassSwitch per binary zone. CONFIG entity_category;
  pairs with the existing diagnostic 'zone bypassed' binary_sensor.

climate.py — OmniThermostatClimate per discovered thermostat.
  Supports OFF / HEAT / COOL / HEAT_COOL hvac_modes; auto / on / diffuse
  fan_modes; none / hold / vacation preset_modes. Single-setpoint and
  range setpoint via TARGET_TEMPERATURE_RANGE. Fahrenheit native (Omni
  panels are F-native; HA handles unit conversion downstream).

sensor.py — analog zones (temperature/humidity/power) + per-thermostat
  diagnostic temp/humidity/outdoor sensors + OmniSystemModelSensor
  + OmniLastEventSensor (event_class + parsed event fields as attrs).

button.py — OmniPanelButton per discovered button macro. Programs not
  yet exposed because the library lacks RequestProperties for Programs.

event.py — single OmniPanelEvent per panel relaying typed SystemEvents
  via _trigger_event. event_types: zone_state_changed, unit_state_changed,
  arming_changed, alarm_activated/cleared, ac_lost/restored,
  battery_low/restored, user_macro_button, phone_line_dead/restored.
  Automations key off platform: event + event_type filter.

helpers.py — extended with security_mode_to_alarm_state,
  ARM_SERVICE_TO_SECURITY_MODE, omni_state_to_ha_brightness +
  ha_brightness_to_omni_percent, omni/ha_{hvac,fan,hold} round-trips,
  fahrenheit_to_omni_raw / celsius_to_omni_raw, analog_zone_device_class,
  EVENT_TYPES tuple, event_type_for(class_name).

__init__.py — PLATFORMS extended to all 8 entity types.

scene.py intentionally NOT created — Omni 'scenes' are user-defined
button macros, already covered by the button platform. Documented in
README; revisit if/when the library gains scene-discovery opcodes.

tests/test_ha_helpers.py: +67 unit tests covering every new helper.
331 tests pass (was 264). Ruff clean across src/ tests/ custom_components/.

e8ed7d1b89 HA Phase A: rebuild coordinator + binary_sensor on v1.0 client + JOURNEY.md
custom_components/omni_pca/coordinator.py — full rewrite:
- Long-lived OmniClient for entry lifetime
- One-shot discovery: system info + zone/unit/area/thermostat/button names
  via list_*_names + per-index get_object_properties
- Periodic poll (30s default): get_extended_status for zones/units/thermostats,
  get_object_status for areas, skip empty discoveries
- Background _run_event_listener task consuming client.events(), patches
  state in-place and async_set_updated_data on push:
    ZoneStateChanged    -> patch zone_status raw byte
    UnitStateChanged    -> patch unit_status state, preserve brightness
    ArmingChanged       -> patch area_status mode + last_user
    AlarmActivated/Cleared -> trigger refresh
    AcLost/Restored, BatteryLow/Restored -> recorded for sensors
- InvalidEncryptionKeyError/HandshakeError -> ConfigEntryAuthFailed (HA reauth)
- OmniConnectionError/RequestTimeoutError -> UpdateFailed + drop client
- Event task cancelled in async_shutdown

custom_components/omni_pca/binary_sensor.py — full rewrite:
- OmniZoneBinarySensor per discovered zone (device class from zone type:
  smoke/water/freeze use latched-alarm bit; doors/motion use current condition)
- OmniZoneBypassedBinarySensor per zone (DIAGNOSTIC, PROBLEM)
- OmniSystemAcBinarySensor (POWER, prefers AcLost/AcRestored push)
- OmniSystemBatteryBinarySensor (BATTERY)
- OmniSystemTroubleBinarySensor (PROBLEM)

custom_components/omni_pca/helpers.py — pure functions extracted for testing:
- device_class_for_zone_type, is_binary_zone_type, use_latched_alarm_for_zone,
  prettify_name. 61 unit tests in tests/test_ha_helpers.py.

docs/JOURNEY.md — 4383-word raw chronological retrospective of the whole
arc from binary archive to working library. 18 dated sections including
the 2191-byte magic-number header validation moment, the two non-public
protocol quirks, the offline-panel comedy. Source material for future
writeups (intentionally raw, not polished).

264 tests pass (was 203, +61 helper tests). Ruff clean across all dirs.

c26db62959 Library v1.0 phase C: stateful mock + e2e for the new surface
src/omni_pca/client.py — wire OmniClient.events() that returns an async
iterator over typed SystemEvent objects (built on events.EventStream).

src/omni_pca/mock_panel.py — substantial expansion:
- Per-object state dataclasses (MockUnitState, MockAreaState, MockZoneState,
  MockThermostatState) plus user_codes table for security validation
- Backward-compat: existing callers passing {idx: 'NAME'} strings still work
  via __post_init__ string-promotion to the matching Mock*State instance
- New opcode handlers:
    Command (20)                  -> Ack with state mutation, dispatches
                                     UNIT_ON/OFF/LEVEL, BYPASS/RESTORE_ZONE,
                                     SET_THERMOSTAT_HEAT/COOL/SYS/FAN/HOLD
    ExecuteSecurityCommand (74)   -> Ack on valid code (mode applied);
                                     Nak on invalid code
    RequestStatus (34)            -> Status (35) for Zone/Unit/Area/Thermostat
                                     hard-coded record sizes per
                                     clsOL2MsgStatus.cs:13-27
    RequestExtendedStatus (58)    -> ExtendedStatus (59) with object_length
                                     prefix, richer fields per object type
    AcknowledgeAlerts (60)        -> Ack
- Synthesized SystemEvents (55) push on state change with seq=0; events round-
  trip cleanly through events.parse_events() (validated by tests, not just
  asserted in code)

tests/test_e2e_client_mock.py — +9 e2e tests covering arm/disarm with code
validation, unit on/off/level, zone bypass/restore, thermostat setpoint,
push events for arming and unit changes, acknowledge_alerts.

203 passed (was 194), 2 skipped (HA harness + .pca fixture). Ruff clean.

Library v1.0 surface complete: read-only, command, status, extended status,
events. Next: rebuild the HA custom_component on top of this.

68cf44a585 Library v1.0 phase B: command opcodes + typed system events
src/omni_pca/commands.py — Command IntEnum (64 values, sourced from
enuUnitCommand.cs which is the canonical 'enuCommand' despite the misleading
name) + SecurityCommandResponse + CommandFailedError exception. Notable
discovery: enuUnitCommand.UserSetting (104) is actually EXECUTE_PROGRAM;
renamed for clarity, C# alias documented inline.

src/omni_pca/client.py — 18 new methods on OmniClient:
  Core: execute_command, execute_security_command, acknowledge_alerts,
        get_object_status, get_extended_status
  Wrappers: turn_unit_on/off, set_unit_level, bypass_zone, restore_zone,
        set_thermostat_{system,fan,hold}_mode,
        set_thermostat_{heat,cool}_setpoint_raw,
        execute_button, execute_program, show_message, clear_message
  All command methods raise CommandFailedError on Nak.

src/omni_pca/events.py — typed SystemEvents (opcode 55) decoder.
- EventType IntEnum (28 dispatch tags)
- 26 SystemEvent subclasses + UnknownEvent catch-all
  Includes: ZoneStateChanged, UnitStateChanged, ArmingChanged,
  AlarmActivated/Cleared, AcLost/Restored, BatteryLow/Restored,
  PhoneLine{Off,On,Dead,Restored}, UserMacroButton, ProLinkMessage,
  CentraLiteSwitch, X10CodeReceived, AllOnOff, DcmTrouble/Ok,
  EnergyCostChanged, CameraTrigger, AccessReaderEvent, UpbLinkEvent
- SystemEvents packets carry MULTIPLE events; public API is
  parse_events(message) -> list[SystemEvent], plus SystemEvent.parse()
- EventStream helper that flattens batches across messages
- Wiring of OmniClient.events() left for next pass

55 new tests across both files. 194 pass, 2 pre-existing skips. Ruff clean.

08974e2ec4 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.

2e439364bd 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.

1901d6ec87 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

                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
