Consolidate 9 separate MQTT modules into a cohesive mqtt package: - Create src/nwp500/mqtt/ package with organized submodules - Combine reconnection logic into connection.py - Update all imports across codebase (mqtt package, examples, tests, CLI) - Create mqtt/__init__.py with clean public API exports - Fix type checking errors in connection.py and client.py - Remove old mqtt_*.py files from src/nwp500/ Benefits: - Clearer package organization and structure - Reduced cognitive load for users learning the system - Better clarity on public vs internal APIs - Easier maintenance and navigation All 209 tests pass with zero type checking errors in mqtt package. --- examples/auto_recovery_example.py | 2 +- examples/combined_callbacks.py | 2 +- examples/command_queue_demo.py | 2 +-

Migrate CLI to Click framework for better command organization * Implemented async_command decorator for automatic loop and connection management * Added support for command groups (reservations, tou) * Improved argument and option parsing with built-in validation * Enhanced help text and version reporting - Centralize command registry in src/nwp500/cli/commands.py * Created CliCommand dataclass for structured command metadata * Defined CLI_COMMANDS registry for easier discovery - Reorganize CLI handlers into src/nwp500/cli/handlers.py * Moved implementation logic from commands.py to handlers.py * Improved separation of concerns between CLI framework and business logic - Infrastructure and Tests * Added click>=8.0.0 dependency to setup.cfg * Updated tests/test_cli_commands.py to use new handler locations * All CLI tests pass with new implementation Benefits: - Better discoverability of available commands - Cleaner command organization and parameter validation - Reduced boilerplate for adding new async CLI commands - Industry-standard CLI framework (Click) --- =1.1.0 | 0 setup.cfg | 1 + src/nwp500/cli/__init__.py | 2 +- src/nwp500/cli/__main__.py | 554 +++++++++++++++++++--------------- src/nwp500/cli/commands.py | 596 ++++++------------------------------- src/nwp500/cli/handlers.py | 508 +++++++++++++++++++++++++++++++ tests/test_cli_commands.py | 2 +- 7 files changed, 905 insertions(+), 758 deletions(-) delete mode 100644 =1.1.0 create mode 100644 src/nwp500/cli/handlers.py diff --git a/=1.1.0 b/=1.1.0 deleted file mode 100644 index e69de29..0000000 diff --git a/setup.cfg b/setup.cfg index 5ed3f16..32515a8 100644 --- a/setup.cfg +++ b/setup.cfg @@ -54,6 +54,7 @@ install_requires = aiohttp>=3.8.0 awsiotsdk>=1.27.0 pydantic>=2.0.0 + click>=8.0.0 [options.packages.find] diff --git a/src/nwp500/cli/__init__.py b/src/nwp500/cli/__init__.py index 59f23fa..0e8659e 100644 --- a/src/nwp500/cli/__init__.py +++ b/src/nwp500/cli/__init__.py @@ -1,7 +1,7 @@ """CLI package for nwp500-python.""" from .__main__ import run -from .commands import ( +from .handlers import ( handle_device_info_request, handle_get_controller_serial_request, handle_get_energy_request, diff --git a/src/nwp500/cli/__main__.py b/src/nwp500/cli/__main__.py index 3124c2f..6df16f9 100644 --- a/src/nwp500/cli/__main__.py +++ b/src/nwp500/cli/__main__.py @@ -1,10 +1,13 @@ -"""Navien Water Heater Control Script -

Comprehensive code review and architectural analysis - ---- - -## Executive Summary - -The nwp500-python library is a **well-crafted, mature project** with solid fundamentals, strong type safety, and good separation of concerns. The main opportunities for improvement lie in **discoverability** (helping developers find what events/fields exist and what they mean) and **consolidation** (reducing cognitive load from fragmented modules and scattered documentation). - -**Overall Grade:** 8.5/10 - Production-ready with areas for refinement - ---- - -## STRENGTHS - -### 1. Well-Organized Architecture -- Clear separation of concerns with dedicated modules (auth, API, MQTT, models, events) -- Logical module responsibilities that are easy to understand -- Good abstraction layers between components - -### 2. Strong Type Safety -- Excellent use of Pydantic for data validation and serialization -- Custom validators with Annotated types for complex conversions -- Type hints throughout the codebase -- MyPy compatibility with type checking enabled - -### 3. Comprehensive Exception Hierarchy -``` -Nwp500Error (base) -├── AuthenticationError -├── APIError -├── MqttError (with 5 sub-types) -├── ValidationError (with 2 sub-types) -└── DeviceError (with 4 sub-types) -``` -- Well-structured, enabling precise error handling -- Clear migration guide for v4→v5 breaking changes - -### 4. Rich Documentation -- Comprehensive README with feature list and CLI examples -- Good docstrings with module-level documentation -- Migration guides for breaking changes -- 35+ example scripts covering various use cases - -### 5. Event-Driven Design -- Flexible EventEmitter pattern allows decoupled code -- Support for priority-based listener execution -- Async handler support -- Good for real-time monitoring scenarios - -### 6. CI/CD Best Practices -- Automated linting with Ruff -- Type checking with MyPy -- Comprehensive test suite -- Version management via git tags and setuptools_scm - -### 7. Security Mindfulness -- MAC addresses redacted from logs -- Sensitive data handling considerations -- AWS credential management via temporary tokens - ---- - -## AREAS FOR IMPROVEMENT - -### 1. MQTT Module Fragmentation ⚠️ [HIGH PRIORITY] - -**Current State:** -Nine separate MQTT-related modules exist: -- `mqtt_client.py` - Main client -- `mqtt_connection.py` - Connection handling -- `mqtt_command_queue.py` - Command queueing -- `mqtt_device_control.py` - Device control -- `mqtt_diagnostics.py` - Diagnostics -- `mqtt_periodic.py` - Periodic requests -- `mqtt_reconnection.py` - Reconnection logic -- `mqtt_subscriptions.py` - Subscriptions -- `mqtt_utils.py` - Utilities - -**Issue:** -- Users importing from `mqtt_client` must understand dependencies on 9 internal modules -- Related functionality is scattered across files (e.g., reconnection logic separate from connection) -- Cognitive load when learning the system -- Unclear which classes users should use vs which are internal - -**Recommendation:** -**Option A (Simplest):** Create an `MqttManager` facade class -```python -class MqttManager: - """High-level interface hiding internal MQTT implementation.""" - - def __init__(self, auth_client): - self._connection = MqttConnection(auth_client) - self._subscriptions = MqttSubscriptionManager(self._connection) - self._control = MqttDeviceController(self._connection) - self._periodic = MqttPeriodicRequestManager(self._connection) -``` - -**Option B (Better long-term):** Reorganize into a package structure: -``` -src/nwp500/mqtt/ -├── __init__.py # Re-exports main classes -├── client.py # NavienMqttClient -├── connection.py # Connection + Reconnection -├── control.py # Device control -├── subscriptions.py # Subscriptions -├── periodic.py # Periodic requests -├── diagnostics.py # Diagnostics -└── utils.py # Shared utilities -``` - -**Impact:** Improved modularity, clearer public vs internal APIs, easier maintenance - ---- - -### 2. Inconsistent Naming Patterns 🎯 [MEDIUM PRIORITY] - -**Issues Found:** - -#### Class Naming -- **Inconsistent prefixes:** `NavienAuthClient`, `NavienAPIClient`, `NavienMqttClient` have prefix, but `EventEmitter` doesn't -- **Missing prefix:** `DeviceCapabilityChecker`, `DeviceInfoCache`, `MqttDiagnosticsCollector` - some use `Mqtt*` some don't - -#### Method Naming -- **Mixed patterns:** - - `request_device_status()` (noun-verb) - - `set_device_temperature()` (verb-noun) - - `list_devices()` (verb-noun) -- **Unclear intent:** `control.request_*` vs API `set_*` patterns - -#### Enum Naming -- **Device protocol mapping unclear:** `OnOffFlag.OFF = 1, ON = 2` - why not 0/1? -- **Mixed conventions:** Some enums are device values (protocol), others are application logic - -#### Exception Naming -- **Vague hierarchy:** `MqttError` vs `MqttConnectionError` vs `MqttNotConnectedError` -- **Consistency:** `InvalidCredentialsError` vs `DeviceNotFoundError` - different naming pattern - -**Recommendation:** -Create `CONTRIBUTING.rst` section with naming conventions: - -```markdown -## Naming Conventions - -### Classes -- Client classes: `NavienClient` (auth, API, MQTT) -- Manager/Controller classes: `` (e.g., MqttConnectionManager) -- Utility classes: `Utilities` or `` (e.g., MqttDiagnostics) - -### Methods -- Getters: `get_()` or `list_()` -- Setters: `set_(value)` or `configure_()` -- Actions: `_()` (e.g., reset_filter()) -- Requesters: `request_()` for async data fetching - -### Enums -- Device protocol values: prefix with domain (e.g., OnOffFlag, CurrentOperationMode) -- Add code comment explaining device mapping (e.g., "2 = True per Navien protocol") - -### Exceptions -- Pattern: `Error` (MqttConnectionError, AuthenticationError) -- Group related errors under base class -``` - -**Impact:** Reduced cognitive load, easier onboarding for new contributors - ---- - -### 3.

Potential Security Considerations 🔒 [MEDIUM PRIORITY] - -**Current State:** -✅ **Good practices:** -- MAC addresses redacted from logs -- Sensitive data not logged -- AWS credential management via temporary tokens - -⚠️ **Areas to strengthen:** -1. **No AWS endpoint validation** - could be vulnerable to MITM if endpoint is overridden -2. **Token storage advice missing** - in-memory only, no guidance on persistence -3. **No rate limiting on auth attempts** - could enable brute-force attacks -4. **Password in examples** - shown in docstrings (albeit with disclaimer) - -**Recommendation:** - -#### Add security documentation: -```markdown -# docs/SECURITY.md - -## Authentication Security - -### Credential Storage - -The library keeps authentication tokens in memory only and does not persist them. - -**DO NOT** save credentials to disk, environment variables, or configuration files -in production environments. Instead: - -1. Use system credential managers (AWS Secrets Manager, HashiCorp Vault) -2. Request credentials at runtime from secure source -3. Use environment variables only in development (with .env in .gitignore) - -### Token Lifecycle - -Access tokens expire in 1 hour. The library automatically refreshes them. -If refresh fails, re-authenticate with email/password. - -### AWS Endpoint - -The library connects to AWS IoT Core using credentials obtained from the API. -Verify the endpoint is `.iot.us-east-1.amazonaws.com` before connecting. - -If you override the endpoint, ensure: -- TLS/SSL is enabled -- Certificate is from trusted CA -- Hostname verification is enabled - -## Rate Limiting - -There is no built-in rate limiting on authentication attempts. -Implement at application level if needed: - -```python -from time import time -from collections import deque - -class RateLimiter: - def __init__(self, max_attempts=5, window_seconds=300): - self.max_attempts = max_attempts - self.window_seconds = window_seconds - self.attempts = deque() - - def is_allowed(self) -> bool: - now = time() - # Remove old attempts - while self.attempts and self.attempts[0] < now - self.window_seconds: - self.attempts.popleft() - - if len(self.attempts) >= self.max_attempts: - return False - - self.attempts.append(now) - return True -``` -``` - -#### Validate AWS endpoint: -```python -# src/nwp500/mqtt_utils.py -import re - -def validate_aws_iot_endpoint(endpoint: str) -> None: - """Validate AWS IoT Core endpoint format. - - Expected format: {account}.iot.us-east-1.amazonaws.com - """ - pattern = r'^[a-zA-Z0-9-]+\.iot\.[a-z0-9-]+\.amazonaws\.com$' - if not re.match(pattern, endpoint): - raise ValueError(f"Invalid AWS IoT endpoint format: {endpoint}") -``` - -**Impact:** Reduced security vulnerabilities, better security guidance - ---- - -### 12. Performance & Async Patterns ⚡ [LOW PRIORITY] - -**Current State:** -- Connection pooling not documented -- Command queue is simple (FIFO) -- No performance characteristics documented -- No latency or throughput guidelines - -**Recommendation:** - -#### Add performance documentation: -```markdown -# docs/PERFORMANCE.md - -## Connection Pooling - -The library uses a single aiohttp session for HTTP requests and a single -MQTT WebSocket connection. This is efficient for single-device control. - -For multiple concurrent devices, consider: - -```python -# ❌ Inefficient: One client per device -clients = [NavienMqttClient(auth) for _ in range(100)] - -# ✅ Better: Share auth, separate MQTT subscriptions -auth_client = NavienAuthClient(email, password) -mqtt_client = NavienMqttClient(auth_client) -await mqtt_client.connect() - -for device in devices: -

-## Throughput - -- MQTT: Up to 10 commands/sec -- API: No documented limit (AWS managed) -- Command queue: Processed at MQTT rate - -## Backpressure Handling - -Commands sent while disconnected are queued (default limit: 100). -If queue fills, oldest commands are dropped with a warning. - -Configure queue size: - -```python -config = MqttConnectionConfig( - command_queue_max_size=200 -) -mqtt_client = NavienMqttClient(auth, config=config) -``` -``` - -#### Profile and benchmark: -```python -# scripts/benchmark_performance.py -import asyncio -import time -
