This PR was opened by an automated Claude Code run. It needs a human review before merging — nobody has tested it against a real installation with real devices.
Description
When a sensor glitches, the wrong value stays in the history forever: there was no way to look at the raw recorded values of a device feature, let alone fix or remove one. This PR adds a small editor for that.
Server — three new functions on the device manager, and three routes next to the existing device_feature ones:
Route
Function
GET /api/v1/device_feature/:device_feature_selector/state
getDeviceFeatureStatesPaginated(selector, { from, to, take, skip }) returns { total, take, skip, states }, most recent first. The query is always bounded in time (it defaults to the last 7 days when no range is given): there is no index on device_feature_id in DuckDB, so an unbounded query would scan the whole history, whereas a bounded window is pruned thanks to the per-row-group min/max metadata — same reasoning as the progressive windows in device.getDeviceStatesHistory.
updateState(selector, createdAt, newValue) and destroyState(selector, createdAt) act on a single state, identified by its (device_feature_id, created_at) pair — the same key db.duckDbUpdateState already uses in device.saveHistoricalState. They 404 when the feature or the state does not exist, and 400 on an invalid date / non-numeric value.
refreshFeatureLastValue(deviceFeature): last_value / last_value_changed on t_device_feature is a denormalized copy of the most recent state. When the edited state is that most recent one, the last value is recomputed from the history and propagated to the DB, the state manager and the device.new-state websocket message — otherwise deleting the glitch would leave the device page still showing it, which is exactly what the request is about. When the edited state is older, nothing is touched (no extra query).
All three routes use authenticated: true, like the neighbouring device / device_feature routes (delete /api/v1/device/:device_selector is authenticated-only too).
Front — a new page at /dashboard/devices/:device_selector/history, reachable from the devices list (a "list" button on the desktop table row and on the mobile item).
Why there: the devices list is where a device is looked up today, and it is the only place in the navigation that maps 1:1 to a device. The dashboard chart box is per-dashboard and per-metric (and is an editing surface for the box, not for the data), and /dashboard/history is a cross-device activity feed with its own live-buffering/grouping logic — grafting a per-feature editor into either would have been more invasive than a dedicated page.
The page has a feature selector, a from/to date range (last 7 days by default), a paginated table of the raw values, inline edit of a value, and delete with an inline confirmation.
i18n added in en, fr and de. Demo-mode fixtures added in front/src/config/demo.js for the two demo devices and their features, plus a small fallback in DemoHttpClient.delete so a DELETE URL carrying a dynamic query string resolves to the URL-only key (the same fallback get already has).
Explicitly out of scope
No recomputation of derived data. Correcting or deleting a state does not re-run the energy/cost calculation that may already have consumed it (energy-monitoring.calculateEnergyFromIndex, calculateCostFrom, …). A warning to that effect is displayed on the page. Wiring a "recalculate from this date" action into the existing energy jobs felt like a separate, larger change; happy to follow up if you want it here.
t_device_feature_state_aggregate is not touched — nothing in the current code writes it (it is only ever deleted, by purgeStatesByFeatureId / device.migrate), so there is no aggregate to keep in sync.
No bulk edit / bulk delete over a selection; only one value at a time. device.destroyStatesFrom already covers "delete everything from a date".
Tests pass: cd server && npm run coverage (Codecov requires 100% coverage on changed lines) and Cypress (npm run cypress:run) if the UI changed
New tests: server/test/lib/device/device.getDeviceFeatureStatesPaginated.test.js, device.updateState.test.js, device.destroyState.test.js, and a Device feature state edition block in server/test/controllers/device/device.controller.test.js. They cover every branch of the four new lib files, including the refreshFeatureLastValue paths (most recent state edited, older state edited, feature with no last_value_changed, and history emptied by the delete).
test/lib/device/** + test/controllers/device/**: 354 passing. npm run coverage itself was not run (no Codecov here).
The full npm test run has pre-existing failures in this sandbox only — gateway backup/restore (sqlite3: not found), Docker-dependent external-integration tests and gateway two-factor/AI tests. None of them touch the device layer, and none of the files they exercise are modified here.
Cypress was not run.
Linter and prettier pass on both front and server (npm run eslint, npm run prettier)
server: npm run eslint → 0 errors, npm run prettier-check → clean.
front: npm run eslint → 0 errors, npm run prettier-check → clean, npm run compare-translations → complete in the 3 languages, npm run build → OK.
When a sensor glitches, a wrong value stays in the history forever: there
was no way to look at the raw recorded values of a device feature, let
alone fix or remove one.
Server:
- device.getDeviceFeatureStatesPaginated: one page of the raw states of a
device feature over a time range (always bounded in time so DuckDB can
prune row groups), returning the total of the range.
- device.updateState / device.destroyState: correct or delete a single
state, identified by its (device feature, created_at) pair.
- device.refreshFeatureLastValue: when the edited state was the current
value of the feature, the denormalized last_value/last_value_changed is
recomputed from the history and propagated to the DB, the state manager
and the websocket.
- Three routes next to the other device_feature routes, with the same
authenticated middleware.
Front:
- New "Value history" page at /dashboard/devices/:device_selector/history,
reachable from the devices list (desktop row and mobile item): feature
selector, date range, paginated table, inline edit and delete with
confirmation.
- i18n in en, fr and de, and demo-mode fixtures for the new routes.

Device history
Layer / File(s)
Summary
State history operations server/lib/device/..., server/test/lib/device/...
Device operations retrieve, update, delete, and refresh recorded feature states. Tests cover pagination, validation, state fallback, cache updates, and websocket events.
History HTTP API server/api/..., server/test/controllers/device/device.controller.test.js
Authenticated GET, PATCH, and DELETE routes expose state history operations. Controller tests verify filtering, ordering, updates, deletions, and errors.
History view and navigation front/src/routes/device-history/..., front/src/routes/devices/..., front/src/components/app.jsx, front/src/config/i18n/...
The frontend adds routing, device history navigation, filters, pagination, inline editing, deletion, localized messages, and responsive styles.
Demo history support front/src/config/demo.js, front/src/utils/DemoHttpClient.js
Demo fixtures provide device metadata and state-history GET, PATCH, and DELETE responses. DELETE requests support query-free fixture keys.
The new history editor lets users view, edit, and delete recorded device values. When filters or pages change quickly, an older request may still overwrite the table with stale history until the page is refreshed, so the change is mergeable with explicit owner awareness or follow-up.

I hop through timestamps, neat and bright,
Editing values by moonlit light.
Old states vanish, new ones stay,
Devices guide the gentle way.
With every page and translated cue,
The history trail grows fresh and true.

Stale comment
This is a useful feature (the forum request is real, and the split between paginated history vs. last_value refresh is the right shape). I am not approving yet: the history page likely fails to load on first paint, and the path that fixes the current glitch reintroduces the unbounded DuckDB Top-N that getDeviceStatesHistory was written to avoid.
Blocker
After getDevice, getStates() is called without waiting for setState. In Preact 10 this.state is only updated on render, so selectedFeatureSelector is still null, getStates returns immediately, and nothing retriggers the fetch. Changing a filter would load data; opening the page would not.
Production concern (same class as the existing history feed)
refreshFeatureLastValue runs ORDER BY created_at DESC LIMIT 1 with only a device_feature_id filter. That is exactly the pattern getDeviceStatesHistory documents as taking tens of seconds on a large DB. It always runs for the main use case (correct/delete the current value). Correcting the current value does not need a scan at all (newValue is already known); deleting it should look up the previous row with a bounded / progressive window.
Not blocking, but worth a pass
Feature dropdown shows feature.name only, which is easy to mix up on MQTT/Zigbee devices with several similarly named features.
Features with keep_history: false still appear and look empty.
Deleting the last row of a page does not clamp skip, so the table can go blank until Previous is clicked.
deviceHistory.actionError talks about saving, but is also used when delete fails.
Cypress was not run; there is no spec for the new page. The devices-list buttons should not break existing E2E, but the editor itself is untested in the browser.
Out of scope (product, not a code defect)
No energy/cost recomputation, with a warning on the page. That is honest, but it is also a large part of why people want this editor. Leaving it to a follow-up is fine if that is intentional.
No new DEVICE_FEATURE_CATEGORIES / DEVICE_FEATURE_TYPES. Routes are authenticated like the neighbouring device APIs (including device delete), not admin-only.
Not risk:high: this is not auth/gateway/crypto, a schema migration, or host power. It does write DuckDB history and last_value, so it should not merge without a human looking at a real install.
Adding needs:human-review and asking @atrovato (author is Pierre-Gilles; this also came from an automated Claude run and has not been tried on a live box).
- front: load the first page of history from the setState callback. setState
is asynchronous in Preact, so the immediate getStates() call read the
selector still null from the constructor and returned early, leaving the
table empty until a filter changed.
- front: skip features with keep_history disabled (they have nothing to edit)
with a dedicated empty state, and label each option of the feature selector
with its category, so features sharing a generic name can be told apart.
- server: never scan the whole history of a feature to refresh its
denormalized last value. On an update, the corrected state is itself the new
last value, so no query is needed. On a delete, the previous state is looked
up with the same progressive time windows as device.getDeviceStatesHistory,
instead of an unbounded Top-N over every state of the feature.

Autofix-Pass: 1
selectFeature, changeFrom, changeTo, nextPage, and previousPage all call getStates without cancelling the request in flight. If a user changes the filter twice in quick succession, the slower response can resolve last and overwrite the newer page. The table then shows data that does not match the selected feature or range.

Consider whether history mutation needs the admin flag.
The PATCH and DELETE routes permanently change or remove recorded history for any authenticated user.

Stale comment
Verdict
Approve. The two blockers from the previous review are fixed in c4d4fcc.
No new DEVICE_FEATURE_CATEGORIES / DEVICE_FEATURE_TYPES. Not risk:high. needs:human-review stays — this is a Claude-generated change that mutates DuckDB history and has not been tried on a live installation; atrovato is already requested.
What was fixed
First-load empty table — getDevice now calls getStates from the setState callback, so the selected feature is applied before the fetch.
Unbounded DuckDB Top-N — correcting the current state passes { lastState } (no history scan). Deleting it looks up the previous row with the same progressive windows as getDeviceStatesHistory (1h → 1d → 7d → 30d → 365d, unbounded last).
Feature options now include category/type, and keep_history === false features are filtered out.
DEVICE.NEW_STATE is emitted without TRIGGERS.CHECK, which is the right call for a manual history edit.
Residuals (non-blocking)
Deleting the last row of a page does not clamp skip, so a chatty feature on page 2+ can land on an empty table until Previous is clicked.
deviceHistory.actionError is still worded as a save failure and is reused on delete.
No Cypress spec for the new /dashboard/devices/:selector/history page (existing E2E should be unaffected; the devices list is not covered today).
Energy/cost is not recomputed (explicitly out of scope, with a page warning). That product call is the main reason for human review, along with a real-install check of edit/delete on a large DuckDB file.
PATCH/DELETE are authenticated like DELETE /device/:selector, not admin. Same as neighbouring device routes; confirm that is intended for irreversible history edits.
- front: format the recorded dates of the device history table with the
active UI language (dayjs localizedFormat + user.language) instead of a
hardcoded DD/MM/YYYY HH:mm:ss, which read as an ambiguous day-first date
in English.
- server: add a direct test suite for device.refreshFeatureLastValue,
covering the caller-supplied last state, the progressive time windows,
the unbounded fallback and the no-previous-state case (100% statements,
branches and lines on that file).

Verdict
Approve. Follow-up d3aa1a0 is a small, correct increment on the already-fixed c4d4fcc:
History timestamps use the active UI language (dayjsL LTS + user.language), matching ApexChartComponent / Clock. English is no longer a day-first DD/MM/YYYY.
server/test/lib/device/device.refreshFeatureLastValue.test.js directly covers the caller-supplied lastState path, progressive windows, the unbounded last-resort fallback, the strict before bound, and the empty-history reset.
The two original blockers remain fixed (first-load fetch via the setState callback; no unbounded Top-N on the common correct/delete-current path).
No new DEVICE_FEATURE_CATEGORIES / DEVICE_FEATURE_TYPES. Not risk:high. needs:human-review stays — Claude-generated change that mutates DuckDB history and denormalized last_value, energy/cost is intentionally not recomputed, and it has not been tried on a live installation. atrovato is already requested.
Residuals (non-blocking, unchanged)
Deleting the last row of a page does not clamp skip, so a chatty feature on page 2+ can land on an empty table until Previous is clicked.
deviceHistory.actionError is still worded as a save failure and is reused on delete.
Rapid feature/range changes can let an older getStates response overwrite the newer page (no request-id guard).
No Cypress spec for /dashboard/devices/:selector/history.
PATCH/DELETE are authenticated like DELETE /device/:selector, not admin.
Narrow race: a live saveState between loading last_value_changed and findPreviousState({ before: deletedAt }) can rewind last_value past a newer reading.
