aiopioneer

Python library for controlling a Pioneer AVR via its built-in API.

Used by the pioneer_async integration for Home Assistant, which was inspired by the original Pioneer Home Assistant integration. Originally developed and tested on a VSX-930 (Main Zone and HDZone outputs) but has since been tested on a larger set of models by the community.

Features

• Implemented in asyncio
• Maintains single continuous telnet session to AVR, with automatic reconnect. This method of accessing the AVR API crashes less often than the integration included with Home Assistant
• Eliminates status polling where AVR sends keepalive responses (on port 8102)
• Auto-detects Zones 1, 2, 3 and HDZone
• Ignore specific zones, for AVRs that report phantom zones
• Automatically polls AVR for source names - no longer need to manually code them in your config any more if your AVR supports their retrieval. Can also set source names manually
• Queries device information from the AVR: MAC address, software version, model
• Ability to set internal parameters to change the API functionality, eg. maximum volume, volume step change delta
• Defaults for internal parameters set via custom profiles based on AVR model
• Includes workaround for AVRs with an initial volume set on the Main Zone (eg. VSX-930)
• Supports AVRs that do not support setting the volume level by emulating using up/down commands (eg. VSX-S510)
• Command line client for sending commands and testing
• Supports all listening mode functions
• Supports all video related functions
• Supports panel and remote locking
• Supports most AMP related functions
• Supports all tone functions
• Supports most zone power functions
• Supports all zone input functions
• Supports all zone volumne and mute functions
• Supports setting of tuner band and preset
• Supports setting tuner frequency directly for AVRs that support this via the API, and also by stepping the frequency up/down

Parameters

There are several types of parameters that modify the library's functionality. These are listed below in order of increasing priority:

• Default parameters: these are the defaults for all of the parameters
• Model parameters: these parameters are determined by the AVR model as detected by the library. Custom profiles for specific AVR models are defined in aiopioneer/param.py
• User parameters: these parameters are provided by the user at instantiation, and can also be updated via the set_user_params method
• Run-time parameters: these parameters are set by the library at run-time

Where a parameter is specified at more than one level, the higher priority parameter takes precedence. Thus, a user specified parameter will override any value that is determined by the AVR model.

Note

YAML syntax is used to indicate values the table below. Use Python equivalents (false -> False, true -> True, null -> None etc.) when calling the Python API directly, and JSON syntax if specifying parameters manually via the Home Assistant integration.

Name	Type	Default	Description
model	str		Device model of AVR. Queried from AVR on connect if not specified
ignored_zones	list	[]	List of zones to ignore even if they are auto-discovered. Specify Zone IDs as strings: "1", "2", "3" and "Z"
command_delay	float	0.1	Insert a delay between sequential commands that are sent to the AVR. This appears to make the AVR behave more reliably during status polls. Increase this value if debug logging shows that your AVR times out between commands
max_source_id	int	60	Maximum source ID that the source discovery queries. Reduce this if your AVR returns errors
max_volume	int	185	Maximum volume for the Main Zone
max_volume_zonex	int	185	Maximum volume for zones other than the Main Zone
power_on_volume_bounce	bool	false	On some AVRs (eg. VSX-930) where a power-on is set, the initial volume is not reported by the AVR correctly until a volume change is made. This option enables a workaround that sends a volume up and down command to the AVR on power-on to correct the reported volume without affecting the power-on volume
volume_step_only	bool	false	On some AVRs (eg. VSX-S510), setting the volume level is not supported natively by the API. This option emulates setting the volume level using volume up and down commands.
ignore_volume_check	bool	false	Don't check volume when determining whether a zone exists on the AVR. Useful for AVRs with an HDZone that passes through audio
zone_1_sources	list	[]	(>0.4) Customises the available sources for use with Zone 1. Defaults to all available sources
zone_2_sources	list	see source	Customises the available sources for use with Zone 2 (some AVRs do not support all sources)
zone_3_sources	list	see source	Customises the available sources for use with Zone 3 (some AVRs do not support all sources)
hdzone_sources	list	see source	Customises the available sources for use with HDZone (some AVRs do not support all sources)
amp_speaker_system_modes	dict	....	Customises the names of speaker system modes. Different generations of AVR will name zones slighty differently. For example, the SC-LX57 names speaker system mode 15 as 5.1ch Bi-Amp + ZONE2 however this can also be called 5.2ch Bi-Amp + HDZONE on newer AVRs
extra_amp_listening_modes	dict	see source	(>0.5) Additional listening modes that are added to the list of all possible listening modes for the AVR. This list is used to decode the listening mode ID returned by the AVR. See the source for the format for listening mode definition
enabled_amp_listening_modes	list	[]	(>0.5) A list of listening mode IDs to be made available for selection. If specified, then no listening mode IDs will be included by default. All enabled source names must be unique, and duplicated names are ignored. The additional listening modes must be actually supported by the AVR, and will return an error (usually E02) when an unsupported listening mode is selected. This list is predefined for some AVRs, and specifying this parameter manually will override the model specific default disable list
disabled_amp_listening_modes	list	[]	A list of listening mode IDs to be disabled. Listening mode IDs that are also specified in enabled_amp_listening_modes will be disabled. This list is predefined for some AVRs, and specifying this parameter manually will override the model specific default disable list
video_resolution_modes	list	['0', '1', '3', '4', '5', '6', '7', '8', '9']	Sets the available video resolutions. Not all AVRs support the same resolution settings. This defaults to all of the latest resolutions from FY16
mhl_source	string	null	Sets the MHL source ID. This is used for media controls. This information cannot be queried automatically
enabled_functions	list	["basic", "audio", "amp", "dsp", "tone", "channels", "video", "tuner", "system", "display"]	Change the functions that are enabled by the API, adding more functions will increase the amount of time it takes to complete a full init and update
disable_auto_query	bool	false	Set to true to disable auto queries on first zone power on for all functions apart from core functionality (power, source, volume and mute)
am_frequency_step	int	null	Optional setting to configure the tuner AM frequency step. If not specified, it will be queried from the AVR if supported by the AVR, otherwise it will be determined by stepping the frequency up and down when the AM tuner is first used
always_poll	bool	false	Always poll the AVR every scan_interval. If set to false, out of band status responses from the AVR will reset the polling interval
debug_listener	bool	false	Enables additional debug logging for the listener task
debug_updater	bool	false	Enables additional debug logging for the updater task
debug_command	bool	false	Enables additional debug logging for commands sent and responses received
debug_command_queue	bool	false	Enables additional debug logging for the command queue task

If your model of AVR always needs specific parameters to be set for the library to function properly, then please create a PR to add a custom profile for the AVR model.

Python API

The library exposes a Python API through the PioneerAVR class. The class methods are listed below:

PioneerAVR.__init__(host: str, port = DEFAULT_PORT, timeout: float = DEFAULT_TIMEOUT, scan_interval: float = DEFAULT_SCAN_INTERVAL, params: dict[str, str] = None )

Constructor for the PioneerAVR class. The connection parameters are used when PioneerAVR.connect is called. After connection is established, the AVR will be polled every scan_interval seconds. If the always_poll parameter is set, the poll timer is reset when a response from the AVR is received. Optional user parameters are provided via params.

Breaking changes

0.8

• To enable params to be accessible from AVR response parsers and also to reduce the size of the main class, the PioneerAVR class has been split out to the classes listed below. References to parameter and properties methods and attributes will need to be updated to be accessed via the params and properties attributes of the PioneerAVR object. All other public attributes have moved to the new classes.
  • PioneerAVRParams contains the user and run-time parameter get/set methods. Some method names have changed, please consult the updated documentation for details
  • PioneerAVRProperties contains the cache of AVR properties collected from its responses
  • PioneerAVRConnection contains the connection related methods, although PioneerAVR inherits from the new class so the connection methods are still accessible via the PioneerAVR class
• Commands that are sent to the AVR to perform full updates are now executed via the command queue. This eliminates the previous interaction between the updater and command queue threads, as the updater now simply schedules updates via the command queue
• The order of queries during a full update has been modified so that amp, DSP and tone queries are executed before video queries
• The Zones enum has been renamed Zone for improved consistency
• The param module has been renamed params for improved consistency
• Exception handling within the AVR interface methods has been made more robust. The AVR listener and responders will now only trigger disconnection from the AVR (and reconnection if requested) if the AVR connection drops. Notably, parser exceptions and timeouts to power, volume and mute queries will no longer cause the AVR connection to disconnect and reconnect. This should fully resolve issues such as crowbarz/ha-pioneer_async#54
• Not detecting Zone 1 on the AVR on module startup has been demoted from an error to a warning and Zone 1 is assumed to exist. Despite this change, most AVR commands will still not work when the AVR is in this state. It is now up to the client to check that Zone 1 has been discovered and handle the case when it is not
• The source AVR zone property has been renamed source_id, and an additional source_name property has been introduced that contains the mapped name for the source for each zone
• The query_device_model method has been introduced to query the device model and set default model parameters. Previously, the query_device_info queried all device information including the device model regardless of whether the AVR main zone was powered on. Clients that previously called query_device_info at module startup should now call query_device_model. query_device_info will be automatically called when the main zone is powered on for the first time after connecting, and no longer needs to be called by the client
• If Zone 1 is not powered on at integration startup, queries for AVR device info is deferred until Zone 1 is first powered on.
• The query_audio_information and query_video_information commands have been renamed query_basic_audio_information and query_basic_video_information. These basic query commands, in addition to query_listening_mode, are executed with a delay after all zone power and source operations whenever any zone is powered on
• The system_query_source_name has been renamed to query_source_name to avoid being sent during AVR device info queries
• The query_sources method has been removed. PioneerAVRParams.get_runtime_param(PARAM_QUERY_SOURCES) should be used instead
• The update_zones method has been removed. Change the AVR zones by recreating the PioneerAVR object with the new zones
• The PioneerAVR.initial_update property has moved to run-time param PARAM_ZONES_INITIAL_REFRESH and is now a set of Zone. The PioneerAVRParams.zones_initial_refresh property is provided as a convenience to access this run-time parameter
• System parameters have been re-termed as run-time parameters to better reflect their function
• The PioneerAVRProperties.zones property now has typing set[Zone]

0.7

• Most PioneerAVR methods now raise exceptions derived from PioneerError when an error is encountered, rather than returning false, None or similar error value. Some instances that currently raise ValueError or SystemError will also raise PioneerError subclasses in the near future
• send_raw_request no longer accepts an argument ignore_error and will always raise exceptions on error. Use ignore_error with send_command to have exceptions handled for you
• asyncio yields have been optimised and minimised, which may cause certain sequences of operations to happen in a different order

0.6

• Python requirement bumped to 3.11 for StrEnum
• Zones enum now used on all methods accepting zone arguments (except in params)
• Zone argument removed from tuner methods as tuner is independent of zone
• TunerBand enum now used to specify a tuner band
• update now waits for the update to finish by default
• set_tuner_preset has been renamed to select_tuner_preset
• get_zone_listening_modes has been renamed to get_listening_modes
• set_listening_mode has been renamed to select_listening_mode
• tuner_*, get_zone_listening_modes, set_panel_lock, set_remote_lock and set_dimmer methods no longer accept a zone argument
• The suffix argument of the send_command method has been reordered after the prefix argument
• Response codes marked --- now return None
• Dimmer mode, tone mode and dB strings have been updated

0.5

• get_sound_modes was renamed to get_zone_listening_modes to reflect Pioneer AVR terminology
• disable_autoquery was renamed disable_auto_query to better match the underlying variable name
• amplifier_speaker_system_modes and disabled_amplifier_listening_modes were shortened to amp_speaker_system_modes and disabled_amp_listening_modes respectively

0.4

• zone_z_sources was renamed hdzone_sources for even more consistency

0.3

• zone_h_sources was renamed zone_z_sources for consistency

0.2

• volume_step_delta has been removed entirely
