HomeAssistantWebSocketWorker holds a persistent state_changed subscription per HA endpoint that opts in via the connector's WebSocket toggle (HaEndpointConfig.UseWebSocket): auth handshake, subscribe, ingest in real time, capped-backoff reconnect. The REST poll worker skips WS endpoints so each is served once. HaWebSocketProtocol holds the pure handshake/parse logic. Verified by 11 protocol unit tests + a live integration test against an in-process fake HA server. CLAUDE.md updated.

Adds a meter hierarchy and a flow view: a downstream meter is a *subsection*
of an upstream one (not an addition), so you can see where a main meter's flow
divides — e.g. official water → garden, pool, other; grid/battery → all → car.
- MeterLink (schema + migration AddMeterLinks): a directed from→to flow edge.
Multi-parent allowed (a merge, e.g. grid + solar → house); multi-child is a
split. Cascade-deletes with either endpoint; unique + distinct-endpoint checks.
- FlowService: per energy type + period, builds a Sankey graph — nodes = meters
sized by consumption; link value = downstream meter's consumption, split
proportionally across multiple upstreams; unaccounted remainder under a meter
becomes a synthetic "Other" node; depth via topological longest-path.
- SankeyChart.razor: hand-rolled inline-SVG Sankey (ApexCharts has no Sankey
type) — columns by depth, nodes stacked by value, bezier ribbons sized by flow,
left→right, theme-aware, HTML-encoded labels, tooltips. Built as a MarkupString
to sidestep Razor's <text> element clash.
- /energy/{id} page (one per energy type): KPIs (consumption + cost), the flow
Sankey, and the meter list. NavMenu now lists a link per energy type
(Electricity, Water, Gas, …) loaded from the DB.
- Meters admin: cycle-safe "Sub-meter of (upstream meters)" multi-select
(descendants excluded to prevent cycles); reconciles meter_link rows on save.
- Reference data seeds a demo chain (Haus → Auto) so electricity flow shows
Haus dividing into Auto + Other.
Tests: FlowServiceTests (single-parent remainder; two-parent proportional
split); render test now asserts the flow chain + covers /energy/{id}. 69 Core +
47 Integration = 116 green. Live-verified: Haus 95,450 kWh → Auto 51,909 +
Other 43,541 (flow conserved), all 5 energy-type pages render.

Three requested phases.
1) Admin section (SDD §8.7) — MudBlazor inline-dialog CRUD, consistent pattern,
delete guards, snackbar feedback, shared Confirm helper:
- Energy types: create/edit/delete (blocks delete when meters reference it).
- Meters: create/edit/delete; recomputes consumption when mode/baseline
changes (NormalizationService over a fresh factory context, in a tx);
delete cascades data (consumption+readings are Restrict → removed first).
- A meter's ingest sources: manage on the meter-detail Sources tab
(add/edit/delete MQTT/Tasmota/HA sources with typed config).
- Tariffs: full CRUD (scope/component/value/validity).
- Cost categories: CRUD + member management (meter or energy-type members).
- Connectors: ingestion_endpoint CRUD (MQTT broker + Home Assistant);
secrets referenced by env-var name only, never stored.
- Settings: read-only effective-config view (settings are env-driven and
reproducible, so an editable form would change nothing — kept honest).
PV role is now editable on meters (MeterMeta.SetRole can clear a role).
2) Read Home Assistant — extracted a shared public HaEndpointConfig (was a
private record in the worker), added HaConnectionTester (powers the connector
"Test connection": checks base URL + env-resolved token, optionally reads one
entity). Configuring an HA connector + an HA source on a meter drives the
existing REST-poll worker end to end. (WebSocket push stays a future
optimization; REST poll already reads HA.)
3) Wiring/placeholder audit — swept every OnClick/Href: all handlers are real,
all internal links resolve to real routes, no TODO/stub/placeholder code.
Fixed one genuine gap: MainLayout had no drawer toggle, so the nav was
unreachable on narrow screens — added a hamburger button.
Tests: +6 (MeterMeta.SetRole role-removal; HaConnectionTester fail-closed
guard branches with a throwing HttpClientFactory proving no network on bad
config); render test now covers all admin routes. 69 Core + 45 Integration =
114 green. Live-verified in Docker: all admin pages 200, drawer toggle present,
Settings shows real effective config.

Complete the SDD §8 dashboard views that were deferred at the M5 boundary,
and fix a shipping bug that left the Docker demo empty.
Bug: "Load reference data" created meters/tank/tariffs but imported zero
readings in Docker. Root cause: sampledata/ was excluded by .dockerignore and
never copied into the build stage, so the App csproj's linked Content glob
resolved to nothing at publish time; ReferenceDataImporter then silently
skipped the missing CSVs after already writing its marker meter, leaving the
DB permanently "loaded" but empty.
- .dockerignore: stop excluding sampledata/
- Dockerfile: COPY sampledata/ into the build stage
- ReferenceDataImporter: fail-fast (validate CSVs exist before the marker
meter) and throw instead of silently skipping a missing file
- Program.cs + MeterVaultOptions: opt-in MeterVault__SeedReferenceData
(compose METERVAULT_SEED=true) for a one-command populated demo
New SDD §8 panels (read models in Infrastructure/Dashboard, Blazor pages):
- §8.4 Solar/PV (/solar): generation from GenerationCounter meters;
self-consumption / autarky % / self-consumption % / savings derived from
meters tagged total_load & grid_import via Meter.Meta role config
(MeterRoles/MeterMeta) — nothing hardcoded by name.
- §8.5 Oil/consumable (/consumables): tank level (cm→L calibrated), fill
gauge, deliveries log, burner runtime, effective L/h (fixed/empirical),
forecast-to-empty, tariff cost, monthly series.
- §8.6 Meter detail (/meters/{id}): raw readings, normalized consumption,
source status, tariff timeline, events, measured-vs-estimated markers.
- Reusable SeriesChart component; nav links; Meters list rows link to detail.
Tests: MeterMetaTests (Core, +10); DashboardRenderTests extended to assert the
three panel services compute real figures and the new routes render (108 total,
all green). Live-verified in Docker: seed imports 302 readings / 347 consumption
rows; panels render (generation 16,481 kWh, oil 3,967 L) cross-checking the DB.

- Move CI/release workflows from .github/workflows to .gitea/workflows (Gitea Actions),
targeting the master branch.
- docker-publish: push to the Gitea container registry (git.finalfactory.de) with a
lowercased image name; login via github.token or a PACKAGES_TOKEN secret.
- version-tag: gitea-actions bot identity; optional RELEASE_TOKEN to re-trigger the image build.
- Update README/CLAUDE.md/Unraid template/build-and-push.ps1 to the Gitea registry + master.
