After HA finishes its first-run wizard the /api/onboarding endpoint
returns 404 plain-text instead of a JSON step list. The previous
screenshot run blew up trying to json-parse "404: Not Found".
Both call sites (_onboard and _complete_onboarding) now check the
status code first and treat anything non-200 as "already complete --
skip and go to the login path".
Adds the homeassistant service to the external caddy network with
labels for juliet.warehack.ing so caddy-docker-proxy issues a public
cert and proxies traffic to port 8123. Uses the same streaming-
friendly transport tuning the docs-site service uses, because HA's
frontend keeps long-lived WebSockets open for lovelace state pushes
and config flows -- without stream_timeout: 24h etc., caddy closes
the socket every ~15s and the UI churns reconnects.
Keeps the 8123 host-port mapping intact for direct localhost dev
access; public traffic flows over the caddy bridge.
dev/ha-config/configuration.yaml (not tracked here -- root-owned in
the HA container) was updated separately to add:
http:
use_x_forwarded_for: true
trusted_proxies:
- 10.10.16.0/20 # caddy bridge subnet
Without that block HA rejects the OAuth redirect_uri at login because
the auth check sees the internal docker IP instead of the public host.
Replace the brittle bind-mount-over-site-packages trick with a proper
``pip install --no-deps /opt/omni-pca-src`` in the HA container's
entrypoint. This gives HA a real ``omni_pca-2026.5.10.dist-info`` so
the manifest's requirement check passes, plus the v1 subpackage that's
not in the published wheel yet (omni-pca==2026.5.10 isn't on PyPI).
Before: ``--force-recreate`` broke the dev stack because the bind mount
overlaid the package contents but left no dist-info, and HA's uv-based
installer can't fetch omni-pca from PyPI.
After: container recreate just works. ``docker compose restart
homeassistant`` re-installs from the latest local source on every
start, so HA + library are always in sync with the working tree.
Header comments updated to mention the real-panel (UDP/v1) config-flow
fields alongside the existing mock-panel ones.
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.
Some Omni network modules are configured for UDP, in which case PC Access
falls back to the v1 wire protocol (OmniLinkMessage outer = 0x10, inner
StartChar 0x5A, typed Request*Status opcodes) instead of v2's TCP path
(OmniLink2Message + StartChar 0x21 + parameterised RequestProperties).
This adds a parallel implementation rather than overloading the v2 path.
omni_pca/v1/
connection.py UDP-only OmniConnectionV1; reuses crypto + handshake,
routes post-handshake messages through OmniLinkMessage
(0x10) wrapping v1 inner format. Adds iter_streaming
for the lock-step UploadNames/Acknowledge/EOD pattern.
messages.py Block parsers for the typed v1 status replies (zone,
unit, thermostat, aux), v1 SystemStatus, and NameData
(handles both one-byte and two-byte NameNumber forms).
client.py OmniClientV1: read API (get_system_information,
get_*_status), discovery (iter_names + list_*_names),
write API (execute_command, execute_security_command,
turn_unit_*, set_unit_level, bypass/restore_zone,
execute_button, set_thermostat_*). acknowledge_alerts
is a no-op (v1 has no equivalent opcode).
Discovery uses bare UploadNames; panel streams every defined name across
all types in a fixed order with per-record Acknowledge. Verified against
firmware 2.12 — pulled 16 zones, 44 units, 16 buttons, 8 codes,
2 thermostats, 8 messages in one stream.
src/omni_pca/message.py
Fix flipped START_CHAR_V1_* constants. enuOmniLinkMessageFormat says
Addressable=0x41 and NonAddressable=0x5A; our names had them swapped.
Wire bytes were unchanged, so existing tests kept passing — but
encode_v1() with no serial_address now correctly emits 0x5A, which
is what UDP needs.
tests/
test_v1_messages.py 22 cases; payloads are real wire captures
from a firmware-2.12 panel via probe_v1_recon.
test_v1_client_commands.py 20 cases; payload-packing for the Command
and ExecuteSecurityCommand opcodes,
including BE u16 parameter2 and the
digit-by-digit security code form.
dev/
probe_v1.py Phase-1 smoke: handshake + RequestSystemInformation.
probe_v1_recon.py Raw opcode dump for protocol reconnaissance.
probe_v1_stream.py Streaming UploadNames flow exploration.
probe_v1_client.py Full read-path smoke test via OmniClientV1.
probe_v1_write.py Live no-op execute_command round-trip.
.gitignore: ignore dev/.omni_key (probe scripts read controller key from
this file as one fallback option).
Discovery on firmware 2.12: Request*ExtendedStatus opcodes (63/65/69)
NAK on this firmware — only the basic Request*Status opcodes are
implemented, so OmniClientV1 uses those (3 bytes/unit, 7 bytes/tstat,
4 bytes/aux records). HA still gets enough signal for polling; full
properties discovery uses streaming UploadNames instead.
Test totals: 387 passed, 1 skipped (existing fixture skip).
dev/screenshot.py — end-to-end automated demo:
* onboards HA via /api/onboarding (user creation + auth_code flow)
* subsequent runs log in via /auth/login_flow with saved credentials
* adds the omni_pca config entry via /api/config/config_entries/flow
* uses HA's template REST endpoint to discover the panel device_id
* launches a headless chromium via playwright with prefetched auth tokens
* captures 6 deep-linked screenshots:
01-overview.png — Lovelace
02-integrations-list.png — HAI/Leviton sitting next to HA's built-ins
03-omni-pca-config.png — '1 device · 38 entities', custom integration
04-panel-device.png — Omni Pro II device page with full controls
05-entities-omni.png — config_entry filtered entities table
06-developer-states.png — alarm_control_panel.omni_pro_ii_main with
raw_mode_name=OFF, code_arm_required=true,
etc. proving real entity state from mock
dev/docker-compose.yml — mock-panel command rewritten:
* Mounts only src/ and run_mock_panel.py (read-only) instead of the full
project so uv doesn't try to recreate the host's .venv on a RO mount
* Installs cryptography via uv pip install --system
* PYTHONPATH set to /tmp/mock/src so omni_pca imports work without a
package install
dev/artifacts/screenshots/2026-05-10/ — six PNGs from the run.
.gitignore — adds dist/ for build artifacts.
Confirmed end-to-end: HA discovered the integration via mDNS hint
(showed up in the onboarding wizard's compatible-devices step), the
config flow connected to the mock over host.docker.internal:14369,
materialized 38 entities across 8 platforms (alarm_control_panel,
binary_sensor, button, climate, event, light, sensor, switch), and
displayed everything in the device + entity registries with friendly
names and attributes intact. The integration name hash is 38 entities
because the mock seeds 5 zones (binary + bypass) + 4 units + 2 areas +
2 thermostats + 3 buttons + 3 system-level binary sensors + 2 system
sensors + 6 thermostat sensors + 1 event entity = 38 (matches HA UI).
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.
