Meters: record events from the UI, and book consumption in the months it accrued in
Two threads that ended up in the same files. One is navigation: a meter
swap that happened today had no click path at all, and most per-meter
tasks were reachable only by knowing which admin page owned them. The
other is attribution: readings on 1 August and 16 September showed six
weeks of water under September and nothing under August.
Meter events from the UI
Swap, counter reset, tank level, delivery and note are recorded through
MeterEventService rather than ad-hoc inserts, so the dialog's verdict and
the saved result come from the same Validate call, and every record or
delete recomputes the meter inside one transaction. MeterEventRules
decides which events a mode offers -- a tank has no register to swap, and
Correction is offered nowhere because nothing reads it.
A swap is stored as the event at T plus a manual reading of the new
register's start value at exactly T. That pairing is the whole trick: the
boundary window is (previousReading, reading], so the old register's tail
books at T and every later reading counts from the new start. Writing the
old final value as the reading at T instead -- the obvious thing -- double
counts the tail and then rejects every reading the new register produces.
Deleting a swap removes that start reading only while it is still the
untouched start value, and only Manual readings can be deleted at all.
Navigation
The meter page is now the hub: primary entry by mode, a "Record event"
menu, and Edit through a shared MeterEditor that also owns tank setup.
Other pages link into it with MeterLinks (/meters/{id}?tab=...&action=...),
whose action is consumed once after the interactive render and dropped
from the address -- the reverse order flashes the dialog and closes it,
because a circuit's first location change dismisses every open dialog.
The app bar gains a "Find a meter" dialog with the same quick entry.
A source that has no usable connector now links to creating (or enabling)
one and comes back to the same source dialog with the connector picked
and everything typed still there; the draft survives in a circuit-scoped
DraftStore, and the way back is a meter id rather than a URL, so the page
cannot be made to redirect anywhere else. The connector list shows which
meters use each connector, import batches list the meters and categories
they wrote to, the meter editor owns the meter's own cost categories, and
the dashboard's empty cost panel names the first missing step instead of
listing every admin page.
Months
A reading is an instant, and what it measures accrued over the time since
the previous one. Booking the whole delta at the closing reading misfiles
it whenever the interval crosses a month boundary, so a plain increase is
now divided at local month boundaries in proportion to elapsed time, each
share stamped inside its month and marked estimated: the meter recorded a
total, not a shape. The parts always sum to the original.
Imported monthly tables are the exception that keeps the golden fixtures
reconciling. "Mai 2026" carries the register at the end of May but is
stamped on the 1st, so the importer -- the only place that still knows
whether the date cell named a month or a day -- flags it MonthLabel, and
the engine reads it as the end of its month. Inferring that from the
stamp instead would catch day-dated rows: a sheet with "01.08.2026" in it
is not a monthly table, and reading it as one moves two thirds of July
into August.
ReadingTimeline is the single ordering built on that: effective time,
then stamp. The register normalizers walk it, and so do the decrease
guard and the event dialog, which is what stops them disagreeing about
which reading is "previous" -- a sheet imported after live readings of the
same month used to count that month twice, and a mid-month reading below
the month's end value was rejected as a drop. A swap detected in a
monthly table applies from the start of that local month, i.e. to the
first reading in it, and a recorded start value never counts above the
reading it lands on.
Every reader buckets in the configured timezone rather than a hardcoded
one, and turns a requested date into that zone's local midnight, so the
divided shares are read back under the months they were stamped in. The
zone id is normalised to its IANA form, because .NET accepts a Windows id
that PostgreSQL will not bucket by, and both are checked at startup.
Stored consumption is derived, so a rule change reaches a meter only at
its next reading -- weeks, for a meter read monthly. NormalizationUpgrade
records the revision and zone the stored series was built with and
rebuilds everything once at startup when either differs, each meter in
its own transaction. A meter that fails is logged, kept in
normalization_pending and retried at the next start: one bad series must
never keep the application down.
What an operator sees once
Existing charts change on the first start after the update: months that
carried a neighbour's use give it back. Rows of earlier imports from
monthly tables are marked as such before anything is recomputed, and if
that marking fails nothing is rebuilt or recorded, so the upgrade simply
runs again next time rather than shifting every imported month by one. A
wizard import whose date format was left on auto-detect is treated as a
monthly table when all of its rows sit on the 1st across at least two
months -- exactly how those rows were attributed before -- and each such
batch is named in the log, because a day-dated sheet always read on the
1st looks identical; revert and re-import it with the day format if that
is what it was.
Tests: 120 unit and 230 integration, including the reference fixtures,
which still reconcile month for month.

i18n: ship the UI in English and German
ci / build-test (push) Failing after 35s
The last open item on the M7 list. Number and currency formatting was already locale-aware, but every string in the UI was an English literal, so a German instance read half in each language -- German data, English chrome. This translates all of it and adds the machinery to keep it translated. Strings live in Localization/Strings.resx (English, neutral) and Strings.de.resx. The neutral file generates a strongly-typed accessor at build time, aliased as S in _Imports.razor, so components reference compiled properties -- @S.Common_Save, not a string key. That choice is the point: across 4,500 lines of markup, a key lookup that silently falls back to its own name is a defect you find in production, while a renamed property is a build error. Generation runs in MSBuild rather than the IDE designer, so dotnet build alone reproduces it anywhere. Resource fallback is the hazard here. Ask for a key the German satellite lacks and ResourceManager quietly serves the English one -- correct at runtime, disastrous at release time, because a half-translated build looks perfectly healthy. StringResourceTests reads each satellite with tryParents: false, which is the only way to see what one actually contains, and fails on a missing or blank translation, a placeholder that changed arity, an orphan, or a key nothing references. Three things needed more than substitution: - Domain enums reached the screen as bare identifiers. They stay bare in the model -- they are persisted as text and appear in the REST API, so their names are part of the data contract -- and DisplayNames is now the single place that decides how each value is spoken. Every arm ends in a fallback returning the identifier, so a value added later cannot throw mid-render; EnumDisplayNameTests is what stops that safety net quietly becoming the shipping behaviour. - Infrastructure was writing display text: FlowService's "Other (X)", MeterPeriodView's "Generation"/"Consumption", the HA connection-test verdicts, the updater's snackbar, the CSV importer's row warnings. Each now returns an outcome value and the UI supplies the words, which is where the reader's language is known. Diagnostics that are not ours -- an HTTP status, systemd's stderr, an exception message -- are passed through untranslated, and every English summary is kept alongside the outcome so log lines never move with the UI language. The UpdateRunner change is additive only; no gate was touched. - Importer warnings carry their arguments rather than a finished sentence, so the numbers inside them pick up the reader's grouping. A register that reads 2.940,19 everywhere else must not read 2940.19 only inside a warning. Switching language is a redirect through /culture/set followed by a full reload, not an interactive state change: a Blazor Server circuit is fixed to the culture of the request that opened it. That makes the endpoint a redirector taking its target from the query string, so anything but a local path is refused rather than followed. Preference order is the cookie, then Accept-Language, then MeterVault__Locale -- an instance can be pinned to one language and a reader can still switch. Locale keeps its documented default of "en". Format now follows CurrentCulture instead of a hardcoded de-DE, so an instance with nothing configured and a browser asking for English will show English number formatting where it previously showed German; set MeterVault__Locale=de to pin the old behaviour. The importer's de-DE parsing is untouched and stays that way -- that dialect is a property of the spreadsheets, not of whoever is looking at the dashboard. Anything that comes from the database -- meter names, energy-type display names, category names -- is user data and is never translated.

Meters: add manual reading entry from the meter-detail Readings tab
ci / build-test (push) Successful in 1m37s
Entering a reading by hand previously meant POST /api/v1/readings with an API key, or a one-row CSV through the import wizard. SourceType.Manual existed in the enum but nothing was behind it. This adds the click path, built for the case it is actually used in: walking to each manual meter with a phone in hand. "Add reading" on the Readings tab opens a dialog prefilled with the meter's last register value and the current local time, both editable: - An on-screen keypad, because a register is read standing at the meter. It behaves like a calculator against the prefill - the first digit replaces it (a fresh register), while backspace edits it in place, which is the common case since only a register's last digits move. - Typed input accepts both separators (last one wins), so a German and an English phone keyboard both do the right thing. ReadingEntry owns that rule and is unit-tested; it deliberately differs from GermanNumber, where a lone dot really is a thousands separator. - A live parsed-value echo plus delta-since-last, which is the net that catches a mistyped digit before it is committed. - Decrease / replaces-existing / future / backdated surfaced before saving, and DST spring-forward gaps refused rather than shifted. The verdict line sits in a fixed-height, no-wrap slot above the keypad. That is load-bearing, not cosmetic: an alert that appears there when the value dips below the last reading moves the keys out from under the user's thumb mid-entry, which is a guaranteed mistype on a phone. The long-form explanation goes below the keypad, where reflow is harmless. Saving goes through IngestionService.IngestByMeterAsync, so the monotonic-decrease guard and inline renormalization apply exactly as for any other ingest. A new optional quality parameter stamps the row ReadingQuality.Manual; null preserves today's behaviour, so a source re-reporting the same timestamp updates the value without silently relabelling a hand-entered or imported reading. Also: the meter-detail tabs now render times in the instance timezone per SDD section 10, instead of raw UTC. Without it a reading entered at 18:00 reads back as 16:00. Side effect is that historic imported monthly rows show 01:00/02:00 rather than 00:00 - correct, if noisier. Claude-Session: https://claude.ai/code/session_01D4x3JbNKCSV4cBR9s7bJmX |

Fix defects found auditing the ingestion, import and connector changes
ci / build-test (push) Successful in 1m16s
An audit of this session's commits found several real problems, three of which
lose or expose data. Ordered by severity.
Live recompute was not atomic. RecomputeMeterAsync clears a meter's series with
ExecuteDelete, which commits by itself when no transaction is ambient, and only
then adds the rebuilt rows. Between the two the meter had *no* consumption:
a dashboard read reported zero, and a crash or cancelled request made the loss
permanent, for data the SDD treats as the long-term source of truth (§5.5).
Import and the events API already wrapped their recomputes; live ingestion,
which I added this session, did not. Now shares one transaction, joining an
ambient one rather than nesting.
The MQTT backfill migration counted brokers without regard to is_enabled. One
live broker plus a disabled leftover counted two, declined to backfill, and left
those sources unbound — which under endpoint-scoped routing means silently and
permanently dead. The "two or more is ambiguous" reasoning did not hold there:
the worker only ever connected to enabled endpoints. Corrected by a follow-up
migration rather than an edit, since the original may already have run; it
touches only rows still NULL, so hand-made bindings are safe.
A mapping edited after a dry run committed the *old* staged rows under the
*new* mapping. Readings went to the previous meter while the batch recorded the
current mapping — wrong data, provenance contradicting it, no exception. The
earlier fix re-validated but did not detect staleness. Commit now compares the
mapping against the one the preview was staged under and refuses.
"Test connection" sent a stored token to whatever Base URL was in the dialog.
Encrypting secrets at rest means the UI can decrypt what the operator can no
longer read, so this turned the button into an exfiltration primitive: point it
at any host, the token arrives as a Bearer header. A stored token now only goes
to the origin it was saved for; testing elsewhere requires typing it again.
A source that cannot ingest looked identical to a healthy one. Endpoint-scoped
routing made unbound and mis-bound sources silently dead, while the Sources tab
showed no connector at all and the delete dialog still promised sources would be
"unlinked". Added a Connector column that names the fault, stopped offering
disabled connectors (both workers filter on IsEnabled), and made the delete
warning say ingestion stops.
Virtual meters rendered four zero tiles: they evaluate on read and only
materialize when a cost category references them (§14.1), so summing
consumption is a confident lie about a working meter. They now report nothing
and the page explains why.
Re-importing an overlapping file failed at the database with EF's "An error
occurred while saving the entity changes", naming neither meter nor date — the
diagnosis problem

Meter detail: lead with periods and change, not register totals
ci / build-test (push) Successful in 1m23s
The headline tiles were lifetime consumption, a raw reading count and the register span. None of those answer why someone opens a meter: how much this month, more or less than last, where the year lands, what it costs. A cumulative counter's register value is an accident of when the meter was installed. MeterPeriodService buckets consumption by calendar month in the instance timezone -- via date_trunc(... AT TIME ZONE) rather than EF grouping, because a reading at 00:30 local on 1 January is 23:30 on 31 December in UTC and would be booked to the wrong month (SDD §10). It reports generation for a generation counter and consumption otherwise, so a PV meter stops claiming it consumed 0 kWh. Month- and year-to-date are compared against a projection of the current period rather than its running total. Three days into a month, "12 kWh vs 340 kWh last month" reads as a collapse in usage when nothing has changed. The projection is straight-line on elapsed days -- wrong for anything seasonal, but the honest reading of "at this rate" -- and the UI marks it with a leading ~. A 12-month bar strip gives the shape at a glance. A meter with nothing normalized yet returns an empty history rather than a flat line, which would look like a meter reading zero. Register span, reading count and lifetime total move into a collapsed panel. Still there when needed for an audit, no longer the first thing you see.

Ingestion: derive consumption on ingest, and poll HA in minutes not seconds
ci / build-test (push) Successful in 1m13s
Live ingestion wrote the raw reading and stopped there. Import, the REST push endpoint and the meter editor all recompute afterwards; the MQTT/Tasmota/HA path was the one that did not, so a polled reading landed in `reading` and every derived figure stayed frozen at the last import. Observed on a GenerationCounter: 45 readings, 44 consumption rows, generation pinned to the register value of the last imported reading. Recompute inline rather than behind a debounce. Normalizing a whole meter is cheap at metering cadence and a background dirty-set worker is machinery this does not yet need; the remark on RenormalizeAsync records when it would. Fixes a latent bug this surfaced in NormalizationService: ExecuteDelete drops the consumption rows in the database but leaves them in the change tracker, so a second recompute on the same context threw an identity conflict on (meter, time, kind). One worker scope ingesting two readings was enough to hit it. Detach the stale entries after the delete. Poll interval is now minutes, default 60, replacing seconds/60. A meter answers "how much this month, what will it cost" — an hourly sample answers that exactly as well as a per-second one, with far less raw volume (SDD §5.5). The `pollSeconds` key no longer binds, so existing sources fall back to the 60 default and move from every-60-seconds to hourly, which is the intent. A source that had deliberately set e.g. 300 seconds also lands on 60 minutes. Two test cleanups now delete consumption before the meter: live ingestion never produced any before, so the FK had nothing to trip on.

Sources: scope the connector picker to the source type and require it
The Sources dialog listed every connector regardless of kind, so an HA source could be bound to an MQTT broker and saved happily — then never ingest. The picker was also clearable, and null meant opposite things per path: an HA source with no connector is skipped outright, an MQTT one was subscribed on every broker. Filter candidates by the connector kind the source type needs (HA -> HomeAssistant, MQTT/Tasmota -> MqttBroker; Tasmota has no endpoint kind of its own), clear a selection invalidated by a type change, and preselect the sole candidate so the single-broker case is one click. Offer a link to /admin/connectors when none exists rather than an empty dropdown. Save now rejects a missing or mismatched connector: such a source has no connection details and would silently never ingest, so it should not be possible to save it looking configured.

Fix: enable global interactivity so dialogs/selects actually work
ci / build-test (push) Successful in 1m12s
Editing a meter (any admin dialog, select dropdown, snackbar, dark-mode toggle) did nothing: pages declared @rendermode InteractiveServer individually, but MainLayout — which hosts MudDialogProvider/MudPopoverProvider/MudSnackbarProvider — was rendered by <Routes>, which was static. Inline MudDialogs and MudSelect popovers render through those providers, so with the providers non-interactive no dialog could ever open. Set the render mode on <Routes> and <HeadOutlet> in App.razor (global interactivity) and removed the now-redundant per-page @rendermode declarations (they would otherwise throw "parent already has a render mode"). Why it slipped through: the integration render tests only issue a GET (static prerender), which never exercises the SignalR circuit. Verified this fix with a real headless-browser run (Playwright): the meter edit dialog opens and the "Sub-meter of (upstream meters)" multi-select opens with options — proving the layout providers are now interactive. 116 tests still green.

Admin write-CRUD, Home Assistant connector config, wiring audit
ci / build-test (push) Successful in 1m19s
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.

SDD §8 panels (PV/oil/meter-detail) + fix reference-data-in-Docker
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.
