tajniak81andClaude Opus 5 9abb03ee4f Service history: 0 km is a reading, not a blank
A car collected new sits at 0 km, and every km calculation in the app
quietly refused to work for it. ComputeDerived only filled NextServiceKm
when Km > 0, so a service record entered at 0 produced no next-due
distance at all — the date side worked, because it guards on IsZero(),
which is genuine absence rather than a number that happens to be low.

The same conflation had been copied outward from there. The reminder's
km signal wanted currentKm > 0 before it would count anything down, the
web badge and the service-life ring tested the odometer for truthiness,
formatKm printed an em dash for zero, and fuel and charging rejected a
0 km entry as "odometer (km) is required" — which is the first charge
of an EV on the driveway on delivery day. The phone app carried its own
copy of each. Editing such a car offered an empty odometer box, since
the forms only prefilled a reading above zero.

Everywhere the odometer is a measurement, absence is now tested as
absence: null in the clients, negative on the server, and the required
fields check that the box was filled rather than that the number cleared
zero. Fuel and charging validate Km < 0 instead, and their inputs drop
min="1". Completing a repeating km reminder rolls from the car's actual
reading in every case; the old fallback to the previous target existed
to keep an untracked car off a due date in the past, but CurrentKm +
RepeatKm is ahead of the car by construction, so it could not have
happened.

Left as it was: dueKm, repeatKm and the service intervals, where zero
really does encode "no trigger" and "use the default", and the liters
and kwh checks, since a zero fill is not a fill.

Maintenance is the exception. Its odometer is the one that is genuinely
optional, so zero there still has to mean "not recorded" and those three
sites keep the truthiness test, commented. Fixing that properly wants a
nullable field rather than an int, which is a schema change and its own
commit — the same shape of problem as the latency em dash in 3c4eba8.

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 (the phone omits only data export/import).

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 / superadmin roles; 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:

  1. API Server — configure .env, run setup-pocketbase.mjs, start the server. This must be running for either app.
  2. Web Appnpm install && npm run dev (proxies /api to the server).
  3. Phone Appflutter build apk / flutter run with --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).
