Ryan Malloy 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.

HAI / Leviton Omni Panel — Home Assistant Integration

Native HA integration that talks Omni-Link II directly to your Omni Pro II / Omni IIe / Omni LTe / Lumina controller over TCP. No middleware — HA opens an encrypted session straight to the panel and listens for unsolicited push messages.

This integration is the HA-facing wrapper around the omni-pca Python library; the library handles the wire protocol, this component surfaces it as HA entities.

Install

  1. HACS → Integrations → custom repository → add https://github.com/rsp2k/omni-pca, category Integration.
  2. Install HAI / Leviton Omni Panel, then restart Home Assistant.

Manual

Copy the custom_components/omni_pca/ directory into your HA config/custom_components/ directory and restart HA.

Configure

  1. Settings → Devices & Services → Add Integration → search for HAI/Leviton Omni Panel.
  2. Enter:
    • Host — IP or hostname of the panel (e.g. 192.168.1.50)
    • Port — defaults to 4369 (HAI's reserved port)
    • Controller Key — 32 hex characters, the panel's NVRAM key
  3. Save. The panel's model and firmware appear as a single device, with one binary_sensor per defined zone.

Where do I get the Controller Key?

If you have a .pca configuration export from PC Access, the included CLI extracts the key for you:

uvx omni-pca decode-pca '/path/to/My House.pca' --field controller_key

Otherwise, find it in PC Access under the panel's Setup → Misc → Network page (HAI labels it "Encryption Key 1").

What you get

  • One device per panel — model + firmware reported in the UI.
  • One binary_sensor per defined zone, named from the panel's own zone-name field. OPENING device class for door/window contacts, MOTION for interior PIRs, SMOKE for fire zones, etc., chosen by zone type when the panel reports one.
  • Push updates: zone state changes propagate within a single round-trip thanks to unsolicited-message subscription. The 30-second poll is just a safety net.

Roadmap

  • Areas → alarm_control_panel entities
  • Units → light / switch entities
  • Thermostats → climate
  • Aux sensors → sensor
