grafana: dashboard bundle + dev-stack integration

Adds a self-contained omni-pca/grafana/ bundle (InfluxDB v2 + Grafana
with pre-provisioned datasource and dashboard) plus dev-stack wiring
so iterating against the mock or real panel is one docker-compose-up.

The dashboard has four rows plus an insights row:

  System health   AC, battery, trouble, 24h event count
  Security        area arming state, recent events table, zone trips
  Climate         thermostat temperatures, HVAC mode
  Activity        event rate by type, top toggled units
  Insights        active zone bypasses, button press log, event distribution

Color-coded event_type tags persist across panels (alarms red, restores
green, batteries orange, etc.); explicit no-purple palette per CLAUDE.md.

The bundle is portable: any HA install can use it by running grafana/
docker compose up -d and pasting ha-snippet.yaml into configuration.yaml.
For the dev stack, dev/docker-compose.yml mounts the same provisioning
files so dev and prod stay in lockstep.

Verified end-to-end against the real Our House.pca panel (192.168.1.9):
the dashboard fills with live zone trips, X-10 unit toggles, and
push-event traffic within 30s of HA bootup.

+## [2026.5.16] — 2026-05-16
+
+Program viewer side panel + writeback API + docs link fix.
+
+### Home Assistant integration
+
+- Lit/TypeScript side panel for the program viewer (Phase C): filterable list, slide-in detail panel, structured-English token rendering, REF-token click-to-filter, live-state badges (SECURE / NOT READY / ON 60% / Away / 72°F) sourced from the coordinator, "Fire now" button calling `omni_pca/programs/fire` over the websocket.
+- Program writeback: `DownloadProgram` wire path, HA write API, Clear / Clone UI in the side panel.
+- esbuild bundle committed at `custom_components/omni_pca/www/panel.js` (~34 KB minified) so end-users don't need Node.
+- `manifest.json`: `documentation` URL points at <https://hai-omni-pro-ii.warehack.ing/> (was the GitHub repo); matches the canonical docs site already referenced from `pyproject.toml`.
+
+## [2026.5.14] — 2026-05-14
+
+HACS publishing release — brand assets and validation tooling.
+
+### Home Assistant integration
+
+- `brand/icon.png` (256×256) + `brand/icon@2x.png` (512×512) shipped inline at `custom_components/omni_pca/brand/` for the HA 2026.3 brands-proxy API.
+- WebSocket commands + side-panel registration for an in-HA custom panel surfacing decoded programs.
+- `program_renderer`: structured-English token streams for the HA UI to render conditional logic.
+- `program_engine`: real AND/OR condition evaluator (StateEvaluator decodes records against MockState; replaces the always-passes-AND/always-fails-OR stub).
+- `program_engine`: EVENT programs + event taxonomy (Phase 4), clausal chains WHEN/AT/EVERY + AND/OR/THEN (Phase 5).
+- `__init__.py`: `CONFIG_SCHEMA = cv.config_entry_only_config_schema(DOMAIN)` to satisfy hassfest.
+- `manifest.json`: keys sorted (domain, name, then alphabetical), HTML/markdown removed from i18n strings.
+- Canonical URLs switched to `github.com/rsp2k/omni-pca` (was Gitea-only).
+
+### Library
+
+- `pca_file.py`: progressive `SetupData` decoding — zone types, area assignments, entry/exit delays, temperature format, code PINs, installer/PCAccess codes, perimeter chime, audible exit delay, DST, house code format, time clocks, latitude/longitude/timezone, account remarks extended, 9 per-family description tables, zone options, thermostat type + areas, time_adj / alarm_reset_time / arming_confirmation / two_way_audio scalars.
+- `iter_programs()` for both v1 (UDP) and v2 (TCP) wire dialects.
+- `mock_panel`: v1 `UploadPrograms` streaming + program-echo tests; `MockState.from_pca()` builds state from a real `.pca`.
+- `programs`: multi-record decoder properties (firmware ≥3.0 records), structured-OP AND decoder properties, AND-record u16 fields documented as big-endian on disk.
+
+### CI / packaging

+# Omni Programs side panel — frontend
+
+Lit/TypeScript source for the HA side panel registered by
+`websocket.py:async_register_side_panel`. The build output
+(`../www/panel.js`) is committed so end-users don't need Node installed.
+
+## Edit / rebuild
+
+```bash
+cd custom_components/omni_pca/frontend
+npm install         # one-time
+npm run build       # one-shot — drops a fresh ../www/panel.js
+npm run watch       # rebuild on change (use during HA dev)
+```
+
+The build script (`build.mjs`) bundles the entry point + Lit + all
+imports into a single ESM file at `../www/panel.js`. Source maps are
+inlined in `--watch` mode and stripped in production builds. Output is
+~34 KB minified.
+
+## Layout
+
+| File | Purpose |
+|---|---|
+| `src/omni-panel-programs.ts` | The custom-element entry point. Defines `<omni-panel-programs>` (matching the panel_custom registration). |
+| `src/token-renderer.ts` | Token stream → Lit `TemplateResult`. Each TokenKind gets distinctive styling; REF tokens become buttons that dispatch a click. |
+| `src/types.ts` | TS interfaces mirroring the Phase-B websocket wire shapes. Short keys (`k`/`t`/`ek`/`ei`/`s`) match `websocket.py:_tokens_to_json`. |
+
+## Wire contract
+
+The panel calls three websocket commands (all defined in
+`../websocket.py`):
+
+* `omni_pca/programs/list` — paginated, filterable summaries.
+* `omni_pca/programs/get`  — full structured-English detail for one slot.
+* `omni_pca/programs/fire` — sends `Command.EXECUTE_PROGRAM` over the wire.
+
+The frontend doesn't subscribe to push events; live-state badges
+refresh on a low-frequency poll (`REFRESH_MS = 5000`). That's a
+deliberate scope choice — switching to per-entity event subscription
+is a follow-up if the polling overhead becomes visible on huge installs.

+The frontend talks to the integration via Home Assistant's standard
+websocket API. We register three commands here, all namespaced under
+``omni_pca/programs/``:
+
+* ``omni_pca/programs/list`` — paginated, filterable summary list. Each
+  result row carries the token stream for the one-line summary plus the
+  metadata the frontend needs to filter and drill in.
+* ``omni_pca/programs/get`` — full detail for a single slot. Returns
+  the structured-English token stream for the compact form or the
+  full clausal chain.
+* ``omni_pca/programs/fire`` — send ``Command.EXECUTE_PROGRAM`` over
+  the wire to ask the panel to run a program now. Returns success/error.
+
+All commands take an ``entry_id`` so multi-panel installs can address
+the right coordinator. The frontend's panel UI uses HA's `<ha-conn>`
+WS client; this module just produces JSON-safe dicts.

+## Load real `.pca` data into the mock
+
+By default the mock serves a small synthetic state (five zones, four
+units, …). Point `OMNI_PCA_FIXTURE` at a real `.pca` file to make the
+mock indistinguishable on the wire from the source panel:
+
+```bash
+# dev/.env (gitignored)
+OMNI_PCA_FIXTURE=/fixtures/path/to/Account.pca
+```
+
+The host directory `/home/kdm/home-auto/HAI` is mounted at `/fixtures`
+inside the mock-panel container (see `docker-compose.yml`); adjust the
+mount if your `.pca` lives elsewhere.
+
+The decryption key is auto-derived from a sibling `PCA01.CFG` if one
+exists (this is how PC Access exports usually ship). To override:
+
+```bash
+OMNI_PCA_FIXTURE_KEY=0xC1A280B2   # or --pca-key on the command line
+```
+
+`MockState.from_pca` populates zones, units, areas, thermostats,
+buttons, programs, model byte, and firmware version from the file —
+everything the HA integration reads at discovery time.
+
+## Time-series & dashboards
+
+`docker compose up -d` also brings up **InfluxDB v2** (port 8086) and
+**Grafana** (port 3000). Open Grafana at <http://localhost:3000>
+(login: `admin` / `$GRAFANA_PASSWORD` from `.env`) — the **Omni Pro II
+— Panel Overview** dashboard loads automatically, pre-provisioned from
+[`../grafana/`](../grafana/), the shipping bundle.
+
+To wire HA → InfluxDB, append this block to `ha-config/configuration.yaml`
+(the directory is gitignored because it contains HA auth/state; the
+block lives in `../grafana/ha-snippet.yaml` for production users):
+
+```yaml
+influxdb:
+  api_version: 2
+  host: influxdb
+  port: 8086
+  ssl: false
+  verify_ssl: false
+  token: dev-token-omnipca-9472-fixed-for-dev-stack
+  organization: omni-pca
+  bucket: ha
+  precision: s
+  tags_attributes: [event_type, event_class]
+  include:
+    domains: [alarm_control_panel, binary_sensor, climate, event, light, sensor, switch]
+    entity_globs: ["*omni*"]
+```
+
+Restart HA (`docker compose restart homeassistant`) after editing.
+Within 30 seconds, panels start populating with live data.
+
+The dashboard JSON in `../grafana/provisioning/dashboards/` is the
+source of truth; edits in the Grafana UI don't persist (provisioned
+dashboards are read-only). Iterate by editing the JSON and running
+`docker compose restart grafana` — the provisioner picks up changes
+within ~30s.
+
+To exercise dashboard panels against the mock, trigger HA actions
+(arm an area, toggle a light): the mock pushes the resulting
+`SystemEvent` back to HA, which ships it to InfluxDB, which Grafana
+queries. Each step takes <1s.

+# Grafana dashboard for omni_pca
+
+InfluxDB v2 + Grafana stack pre-provisioned to visualise an HAI/Leviton
+Omni Pro II panel via the `omni_pca` Home Assistant integration.
+Drop-in for any existing HA install — no integration changes required.
+
+![Dashboard overview](../dev/artifacts/screenshots/2026-05-17/grafana-dashboard-final.png)
+
+## What you get
+
+One dashboard, four rows:
+
+- **System health** — AC power, backup battery, system trouble, event count (24h).
+- **Security** — area arming state timeline, recent push-event log, zone trip timeline.
+- **Climate** — per-thermostat current temperatures + setpoints, HVAC mode timeline.
+- **Activity** — event rate by typed event class, unit brightness heatmap.
+
+Data flows: HA entity state → HA's `influxdb:` integration → InfluxDB
+v2 bucket → Grafana Flux queries → dashboard panels.
+
+## Quick start (~5 minutes)
+
+```bash
+cd grafana/
+cp .env.example .env
+# Edit .env — set strong INFLUX_PASSWORD, INFLUX_TOKEN, GRAFANA_PASSWORD.
+# Generate the token with: openssl rand -hex 32
+
+docker compose up -d
+```
+
+Wait ~30 seconds. InfluxDB does first-boot setup (creates the
+`omni-pca` org, `ha` bucket, admin token); Grafana then auto-provisions
+the InfluxDB datasource and the dashboard.
+
+Then add the influxdb integration to your Home Assistant config:
+
+```bash
+# Paste the contents of ha-snippet.yaml into your configuration.yaml.
+# Add `influxdb_token: <your INFLUX_TOKEN from .env>` to your secrets.yaml.
+# Restart HA.
+```
+
+Within ~30 seconds you should see real-time data populating the
+dashboard at <http://localhost:3000> (login: `admin` / your
+`GRAFANA_PASSWORD`).
+
+## Networking notes
+
+The default `ha-snippet.yaml` assumes HA and InfluxDB sit on the same
+docker network and HA can reach `influxdb:8086` by container name.
+Three common variants:
+
+| HA layout | `host:` value |
+|---|---|
+| Same compose stack as this bundle | `influxdb` |
+| HA on the host, InfluxDB in docker | `host.docker.internal` or your LAN IP |
+| Different machine entirely | the InfluxDB host's IP / FQDN |
+
+If you put either service behind a reverse proxy with TLS, set `ssl:
+true` in the HA snippet and supply the public hostname.
+
+## Iterating on the dashboard
+
+The dashboard JSON at `provisioning/dashboards/omni-pro-ii.json` is
+loaded read-only by the provisioner. To change it:
+
+1. Edit the JSON directly, then `docker compose restart grafana`
+   (provisioner picks up changes within ~30s).
+2. Or use the Grafana UI to experiment, then **Dashboard settings →
+   JSON Model → Save to file** and overwrite the file in this repo.
+
+Provisioned dashboards can't be saved from the UI by design — this is
+intentional, so the file on disk stays the source of truth.
+
+## Extending coverage
+
+The bundle is scoped to the `omni_pca` entity surface via the
+`entity_globs: ["*omni*"]` filter in `ha-snippet.yaml`. Drop that
+filter (or add a second `include:` block) if you want to graph other
+HA entities alongside omni data — Grafana's datasource is general
+InfluxDB v2, nothing in the dashboard JSON hard-codes omni-specific
+field names beyond what you'd want to scope to anyway.
+
+A few panel ideas not yet shipped:
+
+- Alarm activation drill-down — filter the event log to
+  `event_type == "alarm_activated"` and show the `alarm_type`
+  (Burglary / Fire / Auxiliary / …) distribution.
+- Zone trip rate histogram — `binary_sensor` zone changes per zone
+  per hour, useful for spotting flaky sensors.
+- Comm health — track integration coordinator state via the panel
+  device's "Comm error" attribute.
+
+## Files in this bundle
+
+| File | Purpose |
+|---|---|
+| `docker-compose.yml` | InfluxDB v2 + Grafana services |
+| `.env.example` | Required environment template |
+| `ha-snippet.yaml` | HA configuration.yaml additions |
+| `provisioning/datasources/influxdb.yml` | Auto-wires the datasource |
+| `provisioning/dashboards/dashboards.yml` | Provisioner config |
+| `provisioning/dashboards/omni-pro-ii.json` | The dashboard JSON |
+
+## Troubleshooting
+
+**"No data" in panels.** Most panels need either continuous state
+updates (climate, security) or push events (event-driven panels).
+Verify HA is shipping data:
+
+```bash
+docker exec -it omni-pca-influxdb influx query \
+  'from(bucket:"ha") |> range(start:-5m) |> limit(n:5)' \
+  --token "$INFLUX_TOKEN" --org omni-pca
+```
+
+If this returns rows, the pipeline is healthy and panels will fill in
+as the panel does interesting things. If it's empty, check HA logs for
+`[homeassistant.components.influxdb]` errors.
+
+**Dashboard didn't auto-load.** Check `docker logs omni-pca-grafana
+2>&1 | grep -i provision` — provisioner errors show up there.
+
+**Stat panels show duplicate values.** Your HA has multiple entities
+matching the regex (e.g. `omni_pro_ii_ac_power` AND
+`omni_pro_ii_ac_power_2` from prior integration reloads). Clean up the
+duplicates in HA's entity registry, or tighten the filter in the
+dashboard JSON.

+# Paste this block into your Home Assistant configuration.yaml.
+#
+# Prerequisites:
+#   1. The grafana stack from this directory is running:
+#        cd grafana/ && cp .env.example .env && docker compose up -d
+#   2. Your HA instance can reach the influxdb container on port 8086.
+#      Common patterns:
+#        - HA and InfluxDB on the same compose stack: use host=influxdb
+#        - HA and InfluxDB on different hosts: use host=<your-influx-ip>
+#        - HA on the host network, InfluxDB in docker: use
+#          host=host.docker.internal or the host's LAN IP
+#   3. Add `influxdb_token: <your INFLUX_TOKEN from .env>` to your
+#      secrets.yaml. Restart HA after editing both files.
+#
+# What this ships:
+#   - All state changes from omni_pca entities (alarm_control_panel,
+#     binary_sensor, climate, event, light, sensor, switch).
+#   - Event entity attributes carried as fields, including the typed
+#     event_class and event_data payload — so Flux queries can filter
+#     by alarm_type, zone_index, etc.
+#
+# Adjust the entity_globs filter if you also want non-omni entities in
+# the dashboard, or tighten it further to scope by area / device.

+          so a connected client sees the panel the .pca came from.
+        * ``programs`` — every non-empty Program record from the 1500-slot
+          table, encoded back to wire bytes so UploadProgram /
+          UploadPrograms serve them exactly as a real panel would.
+        * ``zones`` / ``units`` / ``areas`` / ``thermostats`` / ``buttons``
+          — populated with the names from the .pca's Names section.
+          ``MockZoneState`` entries additionally carry ``zone_type``
+          (the raw ``enuZoneType`` byte from the SetupData installer
+          section), so the mock's Properties replies categorise zones
+          as security / temperature / humidity matching the source
+          panel. Other SetupData-resident fields (per-zone area
+          assignment, unit type, thermostat type, exit/entry delays,
+          options bitmasks) aren't extracted yet — those default to 0.
+
+        ``user_codes`` is not seeded — the .pca only stores code *names*,
+        not the PIN values; the panel keeps PINs in SetupData. Override
+        explicitly if a test needs them.
+
+        Anything else uses MockState defaults. Pass kwargs to override
+        any seeded field.

+"""Structured-English rendering of HAI Omni panel programs.
+
+The decoded :class:`omni_pca.programs.Program` records produced by

+This module turns them into readable sentences modelled on PC Access's
+program editor:
+

+      AND IF Living Room Motion is secure
+      AND IF after sunset
+        OR IF Bedtime Mode is active
+    THEN Turn ON Hallway Light
+     AND Show Message "WELCOME HOME"
+
+Output is a sequence of :class:`Token` records rather than a flat string
+so that consumers (CLI, HA frontend, anything else) can:
+
+* Identify object references (zones / units / areas / thermostats /
+  buttons / messages) — render each as a clickable link to the entity
+  page, badge them with live state, etc.
+* Style keywords (`WHEN`, `AND IF`, `THEN`) separately from object
+  names and values.
+* Recover plain text trivially via ``"".join(t.text for t in tokens)``.
+
+A :class:`ProgramRenderer` is constructed with a :class:`NameResolver`
+and an optional :class:`StateResolver` for the live-state overlay. The
+two resolvers are protocols (any object with the right methods works);
+the convenience :class:`AccountNameResolver` adapts a :class:`PcaAccount`
+and :class:`MockStateResolver` adapts a :class:`MockState` — together
+those cover the two common consumers (offline ``.pca`` snapshot vs.
+running mock panel) without forcing either into a base class.
