Control had two transports and neither fitted the ordinary customer. OCPP waits
for the charger to dial in, which needs a public endpoint it can reach, a
certificate, and a firmware willing to talk to our CSMS. Modbus TCP dials the
charger, which needs the server on the charger's own network. Between them they
cover a charger we host and a charger we stand next to; the common case is a
charger behind someone else's router, and that had nothing.

It was never unreachable, though. The charger holds a connection open to Anker's
own broker — it is how the mobile app drives it from anywhere, and it is the
mqttStatus register the Modbus snapshot has been reporting all along. So a third
control mode joins that broker as the account: get_user_mqtt_info issues a client
certificate, mTLS to aiot-mqtt-eu.anker.com:8883, and commands go out on the same
topics the app publishes on. Nothing on the customer's side has to be forwarded,
addressed or certificated.

What travels is not an API call. The payload is a JSON envelope around a base64
binary frame the device itself speaks — marker, little-endian length, message
type, name/length/type/value fields, XOR checksum — so mqttframe.go is a codec
rather than a client, written from the message maps in anker-solix-api and
anchored on the one frame that project documents byte for byte. A frame whose
fields do not tile exactly up to the checksum is refused rather than half-read:
these arrive over a link we do not control, and a truncated frame must not read
as a charger reporting zeros.

Two of the charger's habits shape the rest. It publishes nothing unless asked, so
a status read arms a telemetry trigger and waits for the next frame, and a poll
inside that window answers from what has since arrived. And a broker connection
costs a fetched certificate and a TLS handshake while the plugin manager builds a
throwaway instance per request — so the connection lives on the account's shared
session beside the auth token, for exactly the reason the token lives there, and
closes itself after five idle minutes.

The transport also sees two signals no other one does: the boost flag, and the
plug and start countdowns. The package doc has said since the first commit that
they are never set and the derived mode must do without them. Here they are set,
so a charger that has been told to start and is counting down a delay says so
rather than sitting in "preparing", and "skip the delay" is offered only while
there is a delay to skip.

The clients generalise instead of growing a second layout. Both snapshots name
the same quantities the same way, so what was Modbus-only in the readouts is now
whichever transport read the charger — ModbusStatus becomes ChargerStatus on the
phone, mb becomes dev on the web. What each transport can be *told* still
differs, and the buttons branch on that: reset and clear-limit stay with OCPP,
the timeout and phase registers with Modbus, skip-delay with the cloud. A command
a transport has no equivalent for is refused by name, saying which one has it.

The cost is worth saying plainly. This leans on Anker's cloud being up and on an
unofficial protocol the app may change under us, where Modbus leans on nothing
but the LAN. And it is checked against the reference implementation's own worked
example rather than against hardware — there is no charger on this end to point
it at.

# 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` / `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), 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](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](API%20Server/README.md)** — configure `.env`, run
`setup-pocketbase.mjs`, start the server. This must be running for either app.
2. **[Web App](Web%20App/README.md)** — `npm install && npm run dev`
(proxies `/api` to the server).
3. **[Phone App](Phone%20App/README.md)** — `flutter 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](Docker/README.md) (PocketBase + API Server +
Web App as three containers) or [Docker-AIO](Docker-AIO/README.md) (all three
in a single image).
