Two cards on the Charging page were answering with a fraction of what the charger and the account actually report, and in both the losses happened quietly, in a parse that kept the fields it recognised and dropped the rest on the floor. Charger information asked three account-wide views and kept fourteen fields. A charger registered on its own is absent from the site view, which is the only one of the three carrying state, charge power and OCPP status — so exactly the charger that stands alone got the column of dashes, and nothing said why. The per-charger station record, get_evcharger_station_info, is what the mobile app opens when you tap a charger, and it is the one view that answers for a charger outside a station; it is now the fourth view, asked per charger, a failure there costing that charger's row and no more. Alongside it, every field each of the four views sent is kept as attrs, under the cloud's own key, nested objects joined with a dot and arrays carrying their index. First view to answer a key wins, which is the rule the named fields already merged by. Two hundred keys and two hundred and forty runes per value keep a station record with a session list from becoming the whole card. Charger readings lost data twice over. The frame decoder skipped any field byte its per-message map could not name, and a message type with no map decoded to nothing at all; those fields are now kept under the message and the byte they arrived in — 0410.c9 — decoded but unscaled, because a factor is half of a meaning and we do not have the other half. Then the projection read forty-odd names into typed fields and dropped the remainder: sessionStartedAt, the per-phase session energies, the three touch modes, the load-balance monitor and its meter flag, the solar monitor. Those land in extra, and the list maintains itself — the four accessors note every key they read, extra is what is left, and a field modelled later stops appearing there without anyone remembering to remove it. Keeping unnamed fields had one consequence worth guarding. An unmapped message now decodes to something rather than nothing, and ingest stamped settingsAt for anything that was not telemetry — the timestamp a control command waits on to say the charger acknowledged it. A frame we cannot read is not an acknowledgement, so the stamp is now conditional on the message type being one we map, while its fields are kept either way. Both cards show the remainder as what it is: the service's own key, no unit, no translation, no renaming, under a heading that says whose words these are. The blocks appear only when there is something in them, so a Modbus charger's readings card and a charger the cloud says nothing more about are unchanged. Naming one of these fields is a later commit, made from evidence; inventing a label for it today would only make a guess look settled. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
DriverVault
A car control & service-tracking system (originally "Car Control Project").
Built incrementally — starting with a car maintenance tracker (modeled on
Car Service.xlsx) and growing toward live integration with the car via a
cellular ESP32 device and third-party services (Toyota Connected, EV chargers).
Architecture
All clients communicate with the database only through the API Server — nothing talks to PocketBase directly.

The Web and Phone apps are at feature parity.
Features
- Maintenance tracking — cars, service history (date/odometer + which parts were changed), and a per-car parts catalog, with next-due date/km status from the spreadsheet formulas.
- Technical checks — the mandatory roadworthiness inspections (przegląd techniczny / MOT / TÜV): result, cost, station and the certificate's valid-until, which overrides the car's interval and drives the next-due date.
- Maintenance log — workshop visits and repairs outside the routine schedule: type/status, workshop, parts used, labour + parts cost, invoice, warranty-until.
- Fuel tracking — refills with derived efficiency (average / best / worst consumption, cost per km, price per litre). Consumption is measured between full tanks, so partial fills roll into the next full one.
- Documents — insurance, registration, road tax and the rest, each with a server-computed renewal/expiry state.
- Reminders — date- and/or odometer-triggered, one-off or recurring, plus read-only reminders the server derives from documents and service records.
- Attachments — one optional file (PDF or image) per service record, technical check, maintenance entry, refill, document and part; fetched back through the API Server, never a public URL.
- Accounts — PocketBase-token login, profile + appearance preferences (theme/locale/date format/currency/font), avatar, email verification, data export/import, and an account-deletion state machine.
- Organizations & roles — multi-tenant
user/admin/superadminroles; admins manage users within their own organization, superadmins span all. Any user without an organization can create one and becomes its admin. - Per-user ownership & sharing — each car has an owner and can be shared with other users as read or write; the UI mirrors the server's access checks.
- Integrations — per-user connectors under a superadmin → org-admin → user cascade. Built-in today: Toyota Connected (read-only vehicle data), the Anker Solix V1 EV charger and the Greencell HabuDen wallbox (read over the owner's own MQTT broker — no Greencell cloud is involved). Apprise joins them as a server-wide connector rather than a per-user one: it hands a message to an Apprise gateway the operator runs, which fans it out to any of the 100+ services Apprise speaks.
- Cars from the manufacturer's own service — import a car straight off a connected account (MyToyota today), choosing what to pull in, and read everything that service knows about it from a dedicated first tab on the car. Generic over providers: the next manufacturer is one adapter in the API Server.
- EV charging control — for Anker Solix chargers the owner can start, stop and limit charging from the Charging screen over whichever of three transports their control mode picks: Anker's own cloud (commands ride the connection the charger already holds to Anker, so nothing has to be reachable — the mode for a charger on a customer's network), Modbus TCP on the local network, or an OCPP 1.6J Central System the charger dials back into.
- Translated UI — the interface reads its text from per-language files (English, Polish, Danish today), with English as the fallback for any untranslated string. See TRANSLATIONS.md.
- Phone biometric login & app lock — fingerprint / face sign-in with an app-lock that requires an unlock on relaunch. See the Phone App README.
Auth model
All apps share one auth model: authentication is PocketBase's own.
POST /api/auth/login is proxied to the PocketBase users collection and the
client keeps the token PocketBase minted — the API Server does not issue its
own JWT. Every protected request carries Authorization: <token> (both
Bearer <token> and a raw token are accepted) and the server re-resolves it
against PocketBase on each call, so a role change or a deletion takes effect
immediately. Tokens are stateless, so there is no per-device session list;
changing an account's password rotates its token key and invalidates every token
already issued. Access to cars/records is gated by per-user ownership and shares;
user management requires the admin or superadmin role. Creating an organization
is the one management action open to a plain user — it promotes them to admin of
the organization they just created.
Domain (from Car Service.xlsx)
- Cars — one per vehicle (was: one spreadsheet sheet), with spec fields (engine / transmission / differential oil, brake fluid, coolant, VIN, fuel type, build / first-registration dates, …) and configurable service intervals.
- Service records — date + odometer per service, plus which parts were changed (oil & oil filter, engine air filter, cabin air filter).
- Parts — per-car catalog of part numbers.
Key spreadsheet formulas, reproduced by the API Server on read:
Next Service Date = service date + serviceIntervalDays (default 365; Excel: =A+365)
Next Service Km = service km + serviceIntervalKm (default 15 000; Excel: =B+15000)
Intervals are configurable per car.
Getting started
Bring up the stack in this order — each app's README has the details:
- API Server — configure
.env, runsetup-pocketbase.mjs, start the server. This must be running for either app. - Web App —
npm install && npm run dev(proxies/apito the server). - Phone App —
flutter build apk/flutter runwith--dart-define=API_BASE=http://<server-ip>:8080/api.
Or skip all of that and bring the whole stack up with Docker, which runs the schema setup itself — see Docker (PocketBase + API Server + Web App as three containers) or Docker-AIO (all three in a single image).
