0.8.0

Breaking Changes

• Replaced interfaces' get_status() method with monitoring_connector(), returning a Readable (and optionally Subscribable) connector object, providing the interface health state as InterfaceStatus value
  • Custom interfaces with get_status() implementation need to be adapted, e.g. by inheriting from ReadableStatusInterface or SubscribableStatusInterface or creating a custom monitoring connector
  • See Monitoring of Interface Status in docs
• Field InterfaceStatus.metrics has been removed
  • Custom get_status() / monitoring connector implementations need to respect the removed field of the named tuple
  • Future metrics reporting for monitoring systems shall use additional SHC connectable objects (like the connector objects of the EventLoopMonitor interface interface)
• Attribute criticality of interfaces has been removed
  • individual interface criticality for the overall application status, reported via the HTTP monitoring endpoint, needs to be configured via WebServer.configure_monitoring (see "Monitoring via HTTP" in docs for more details)
• shc.log.generic moved to shc.data_logging
• PersistenceVariable has been renamed to DataLogVariable and completely reworked in its internal interface and behaviour.
  • See Data Logging in docs for further information
• shc.log.in_memory moved to shc.interfaces.in_memory_data_logging and InMemoryPersistenceVariable has been renamed to InMemoryDataLogVariable
• shc.log.mysql moved to shc.interfaces.mysql and MySQLPersistence has been renamed to MySQLConnector
• Interface of MySQLConnector for retrieving non-logging persistence connector objects has been reworked, with new method persistence_variable()
• New database schema for MySQL interface (when used for value persistence without data logging)

New Features

• New EventLoopMonitor interface, for checking the asyncio event loop health via the monitoring interface
• New Nagios-compatible monitoring script (Nagios Plugin) "check_shc.py" in shc/util/check_shc.py for monitoring the SHC server health via the HTTP monitoring endpoint
• New SimpleInputConnector and SimpleOutputConnector helper classes. They can for example be used to build function-block-like classes for SHC with multiple input and output connectors and internal logics.
• New telemetry connector for Tasmota interface.
• New energy connector for Tasmota interface
  • old energy_x() connectors are deprecated and will be removed in a future release

Misc Improvements

• Improved documentation for web UI widgets: https://smarthomeconnect.readthedocs.io/en/stable/web/widgets.html
• Update UI frontend JS dependencies
• Exceptions during startup are logged and handled gracefully now
• Tests and documentation for MySQL interface
• New settings scale_factor and unit_symbol for ChartWidgets

Internal changes

• We now use flake8 instead of pycodestyle for even stricter code style checking
• New test infrastructure for basic unit-testing of all data logging interfaces

0.7.0

New Features

• The Slider web widget now can be supplemented with two buttons to the left and right via the new constructor parameters left_button and right_button.
  • Including a ready-to-use variant MinMaxButtonSlider with buttons that move the slider to the minimum/maximum value have
• Added the UpdateExchange class: A stateless alternative to shc.Variable, allowing to connect multiple connectable objects through a single point and to split up tuple values by subscribing to individual fields.
• Added the FilePersistenceStore for persisting values over SHC restarts in a JSON file

Breaking Changes

None

Improvements

• The @shc.handler and @shc.blocking_handler decorators now support decorating functions with less than two parameters: origin and value of the value update are only passed to the handler function if the parameters is present.
• Added a logo for Smart Home Connect. The logo is also used as favicon and app icon for the web interface
• Updated SemanticUI framework with many fixes for the web UI (esp. touch event handling of Sliders and the menu)
• Updated all NPM packages to mitigate bugs and security flaws

Fixes

• Fixed possible value update loops, caused by concurrent updates via multiple objects, resulting in inconsistent states in the end. Fixed by delaying re-published value updates (with resetted origin) randomly.
• SHCWebClient: Fixed broken decoding of complex values in reflected value updates (during concurrent updates)
• mypy_variable_plugin: Fixed support for newer MyPy versions

Documentation

• New example of special configuration tricks for KNX connection
• New example of using astropy for sun position calculation and OpenWeatherMap for weather forecast

0.6.2

• Fix missing web UI template files in PyPI distribution packages (both, source and wheel distribution)

(see also Changes from version 0.6.0)

0.6.1

• overhauled (modernized) packaging process
• stripped unnecessary files from package/distribution (esp. old generated web UI artifacts)

(see also Changes from version 0.6.0)

0.6.0

New Features

• Compatibility with Python 3.10 (thanks to @fabaff)
• New Telegram Bot interface
• New Command interface for executing arbitrary shell commands and using their exit code or STDOUT in SHC (thanks to @fabaff)

Breaking Changes

• Web: WebServer.serve_static_file() returns full URL of static file (including WebServer.root_url)
• Web: WebServer.add_js_file() and WebServer.add_css_file() have been replaced with WebServer.add_static_directory()

Improvements

• SHCWebClient interface mitigates more state inconsistencies by reflecting probably conflicting received updates back to the server
• Expressions: Make expressions more efficient by using the published value instead of reading all values upon triggered update
• PulseAudio: shc.interfaces.pulse can be imported without needing libpulse installed to use the PulseAudio datatypes

Fixes

• Web API: Fix InvalidState error after a long poll on the HTTP/REST API has been aborted
• base: Fix detection of (possible) conflicting updates to synchronous .trigger()s for mitigating state inconsistencies in Subscribable._publish()
• Fix exponential backoff timeout when reconnecting to MQTT/SHC API/etc. to reset on successful connection
• Do not include SHC's tests in Pip/PyPI distribution
• PulseAudio: Fix handling of exceptions in *PeakConnector

Documentation

• Added docstring for Connectable.connect()
• Added documentation of the HTTP/REST and websocket API
• Added documentation for configuring web UI
• Added documentation and example for creating custom web UI Widgets

0.5.0

• New Pulseaudio interface for monitoring and controlling volumes, mute and sink/source state
• New Variable.field() method for accessing VariableFields of NamedTuple-typed variables (see Docs)
  • Deprecation: Access to VariableFields via attributes is now deprecated in favor of the new .field() method
  • New MyPy Plugin for typechecking VariableFields
• New datatype FadeStep for processing dimming/fading actions
• New FadeStepAdapter and FadeStepRamp for connecting FadeStep-typed objects to Range-typed Variables
• Added Support for KNX DPT 3.xxx (Dimming) with new datatype KNXControlDimming, compatible with FadeStep

0.4.0

• New decorator @expression for creating SHC expressions from simple Python functions
• New Multiplexer expression
• New Ramp generators
• New interface Ping
• New energy sensor connectors for Tasmota interface
• Frontend web assets are now pulled from NPM and bundled with Parcel.js when building the Python distribution
• Updated frontend web asset versions
• Updated Python dependency versions, esp. adding support for Jinja2 3.x.

Version 0.3.1 (development snapshot)

Fixes

• shc.handler() decorator does not mistake Expressions in the origin for recursive execution of the handler anymore

Version 0.3 (development snapshot)

Major changes (probably breaking)

• Rework of subscription system (asynchronous publishing, _publish is no coroutine anymore, origin clearing for state consistency)
• Interfaces' wait() method dropped
• persistence module renamed to log and completely refactored

Other major changes

• New SHC websockt client interface
• New MQTT & Tasmota interfaces
• New web UI widgets for logging
• New helper classes (e.g. Hysteresis, TimerSwitch, BreakableSubscription)

… and many, many minor changes and fixes
