Instead include a short migration README that helps developers move from the old API to the new device-centric API. +- Include unit-test and integration-test guidance and examples. + +## Overview of the new design + +Top-level components: +- FmdClient: an async client that manages session, authentication tokens, request throttling, and device discovery. +- Device: represents a single device and exposes async methods to interact with it (async refresh(), async play_sound(), async get_location(), async take_front_photo(), async take_rear_photo(), async lock_device(), async wipe_device(), etc). +- Exceptions: typed exceptions for common error cases (AuthenticationError, DeviceNotFoundError, FmdApiError, RateLimitError). +- Utilities: small helpers for caching, TTL-based per-device caches, retry/backoff, JSON parsing. + +Rationale: +- Home Assistant requires async-enabled integrations to avoid blocking the event loop. Converting to async lets this library integrate smoothly. +- Representing a device as an object makes the API easier to reason about, test, and extend. +- Centralized client manages authentication and rate-limiting across multiple Device instances. +- Avoiding a built-in legacy shim keeps the code simple and encourages direct migration. + +## Public API + +Example usage: + +```python +from fmd_api import FmdClient + +async def example(): + client = FmdClient(username="me@example.com", password="hunter2") + await client.authenticate() + + devices = await client.get_devices() # list[Device] + device = devices[0] + + # Get latest known location (from cache or backend) + loc = await device.get_location() + + # Force a refresh from backend + await device.refresh(force=True) + + # Trigger play sound + await device.play_sound() + + # Take front and rear photos + front = await device.take_front_photo() + rear = await device.take_rear_photo() + + # Lock device with message + await device.lock_device(message="Lost phone — call me") + + # Wipe device (dangerous) + # await device.wipe_device(confirm=True) + + # Close client when finished + await client.close() +``` + +Core classes and signatures (proposal): + +- FmdClient + - __init__(self, username: str, password: str, session: Optional[aiohttp.ClientSession] = None, *, base_url: Optional[str] = None, request_timeout: int = 10, rate_limiter: Optional[RateLimiter] = None, cache_ttl: int = 30) + - async authenticate(self) -> None + - async get_devices(self) -> list["Device"] + - async get_device(self, device_id: str) -> "Device" + - async close(self) -> None + - properties: + - auth_token (read-only) + - is_authenticated: bool + - cache_ttl: int + +- Device + - Attributes: + - client: FmdClient (back-reference) + - id: str + - name: str + - model: Optional[str] + - battery: Optional[int] + - is_online: Optional[bool] + - last_seen: Optional[datetime] + - cached_location: Optional[Location] + - raw: dict + - Methods (async): + - async refresh(self, *, force: bool = False) -> None + - Updates device state and location from backend.

No functional changes to endpoints or command behavior are intended. +- Where current code uses synchronous HTTP (requests), the new client will use asyncio/aiohttp to make non-blocking calls. Helpers will be introduced to convert existing request/response handling functions to async easily. +- Device.refresh() mirrors current "get devices" and "refresh device" flows: fetch the device status endpoint, parse location, battery, and update fields. +- Photo functions: take_front_photo() and take_rear_photo() call the corresponding FMD endpoints (if supported). They should return either a PhotoResult object (preferred) or None if not supported by the device/account. Implementations should include sensible timeouts and handle partial results gracefully. +- Caching: to avoid hitting rate limits and reduce backend load, a per-device TTL cache will be implemented (configurable; default 30 seconds). get_location() uses cached data unless force=True or stale. +- Rate limiting: a shared RateLimiter object will enforce a maximum requests-per-second or requests-per-minute per client instance. Simple token-bucket or asyncio.Semaphore + sleep-backoff will be sufficient. +- Retries: transient HTTP errors will be retried with an exponential backoff (configurable; default 3 retries). +- Error handling: HTTP 401 triggers AuthenticationError; 404 for device endpoints raises DeviceNotFoundError; 429 triggers RateLimitError. + +## Async design considerations + +- Use aiohttp.ClientSession for requests. The session can be provided by a caller (for reuse) or created by the client. +- All public methods are async and return without blocking the event loop. +- Methods that call multiple network endpoints (for example, refresh that fetches multiple resources) should gather coroutines where parallelism is safe, using asyncio.gather. +- Allow integration with Home Assistant through the standard pattern: construct client during integration setup, call client.authenticate() in async_setup_entry(), create entities that hold Device references, and use DataUpdateCoordinator(s). + +## Migration notes (from current repo) + +- We will NOT ship an in-code legacy compatibility adapter. Instead, include a short README (docs/MIGRATE_FROM_V1.md) with: + - A mapping table of old function names to the new FmdClient/Device equivalents. + - Short code snippets showing how to migrate common flows (list devices, refresh, ring, take photos). + - Notes about switching to async and recommended patterns for calling from synchronous scripts (e.g., using asyncio.run or running inside an existing loop). +- Example migration snippet: + +Old v1 (sync): +```python +d = get_device("device-id") +location = d["location"] +ring_device("device-id") +``` + +New v2 (async): +```python +client = FmdClient(username="u", password="p") +await client.authenticate() +device = await client.get_device("device-id") +location = await device.get_location() +await device.play_sound() +``` + +## Testing + +- Unit tests: + - Mock aiohttp responses using aioresponses or pytest-aiohttp. + - Test Device.refresh, Device.get_location caching behavior, play_sound, take_front_photo/take_rear_photo, lock_device, wipe_device, error mappings, and retry logic. +- Integration tests: + - Optionally include an integration test suite that can run against a staging backend or recorded responses (VCR-like fixture). +- Linting: + - Enforce mypy typing for public API and add tests that ensure Device methods are awaitable. + +## Implementation plan (phased) + +1.

It replaces the legacy synchronous v1 client and prepares the project for Home Assistant and broader integration. + +## Highlights +- **Async client** + - New `FmdClient` with an async factory (`await FmdClient.create(...)`) and async context manager (`async with ...`). + - Clean session lifecycle management and connection pooling controls. +- **TLS/SSL** + - HTTPS-only `base_url` enforcement (rejects plain HTTP). + - Configurable validation: `ssl=False` (dev only) or pass a custom `ssl.SSLContext`. + - Certificate pinning example included in docs. +- **Reliability** + - Timeouts applied across all HTTP requests. + - Retries with exponential backoff and optional jitter for 5xx and connection errors. + - 429 rate-limit handling with Retry-After support. + - Safe behavior for command POSTs (no unsafe retries). +- **Features** + - Client-side export to ZIP (locations + pictures). + - Device helper with convenience actions (e.g., request location, play sound, take picture). +- **Safety and ergonomics** + - Sanitized logging (no sensitive payloads); token masking helper. + - Typed package (`py.typed`) and mypy-clean. +- **CI/CD** + - GitHub Actions: lint (flake8), type-check (mypy), unit tests matrix (Ubuntu/Windows; Py 3.8–3.12). + - Coverage with branch analysis and Codecov upload + badges. + - Publish workflows for TestPyPI (non-main) and PyPI (main or Release). + +## Breaking changes +- API surface moved to async: + - Before (v1, sync): `client = FmdApi(...);

messages mask sensitive data. + +## Documentation and examples +- README: TLS/self-signed guidance, warnings, and certificate pinning example. +- Debugging: `pin_cert_example.py` demonstrates secure pinning and avoids CLI secrets. + +## CI/CD and release automation +- Tests: unit suite expanded;
