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).
