The service badge has always watched two triggers - the next-due date and the next-due odometer reading - and shown one of them. It ranked the two and printed the worse one's sentence, so a car comfortable on both read "OK · 354d" and never said that the odometer target was 13.612 km away, even though the Information card right under it prints the 15.000 km the badge is counting towards. Whichever trigger arrives first ends the interval, so naming only one of them describes half the thing. Both are named now. With both signals known the label is a severity headline followed by each trigger as a bare quantity - "OK · 354d · 13.612 km", "Due in 12d · 13.612 km" - which is the shape reminderStatus in the same file already uses, it having had the two-trigger problem first. The signals gained the number behind their own wording to make that possible; they were returning only a formatted sentence. Wording is unchanged wherever only one signal has data, which is the case this rewrite most risked disturbing: a car with no odometer target still reads "OK · 354d" exactly as before, one with no service date still reads "13.612 km left", and neither still reads "No data". The new keys are only reached when there are genuinely two numbers to print. An overdue badge lists only the triggers that have actually passed. "Service Overdue 30d · 13.612 km" would read as overdue by 13.612 km, which is the opposite of what that number means, so the trigger that is still comfortable stays out of a sentence headed "Overdue". It costs the remaining distance on a date-overdue badge; the alternative costs the reader's trust in the number. The phone carried a line-for-line copy of this logic and gets the same treatment rather than being left a version behind - the two would otherwise disagree about the same car on the same day. Its signals become a private record type, since Status is public and shared with the expiry, reminder and warranty badges that have no second trigger and no use for the field. Two new keys (status.okIn, status.serviceOverdueBy) in all three languages in both apps. The day and km fragments they interpolate were already translated for the reminder badge, so the parts assemble in Polish and Danish without new wording: "OK · 354 dni · 13 612 km", "OK · 354 d · 13.612 km", each with its own grouping separator. Verified by flutter analyze (clean), flutter test - 21 pass, including the key-parity test that would have caught a key added in English alone - and npm run build for the web. The web function was driven through the real module in a browser over ten cases: both signals known at each severity, each of the two overdue alone, both overdue together, either signal missing, neither, and a zero-odometer car, in all three languages. Not verified: no new automated test covers this. The web app has no test runner and the phone's format tests cover the catalogue lookups rather than the badge, so the ten cases above were checked by hand and are not guarded against the next edit. The deployed Web App still serves the previous build and will keep reading "OK · 354d" until it is redeployed. 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) and the Anker Solix V1 EV charger.
- 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 API Server runs an OCPP 1.6J Central System; in own/proxy mode the charger dials back in and the owner can start/stop and set limits from the Charging screen.
- 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).
