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

Params

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

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

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

Name Type Default Description
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).
hdzone_volume_requirements list ["13", "15", "05", "25"] A list of sources that HDZone must be set to for volume control, some AVRs do not support HDZone volume at all (see ignore_volume_check above) and some only allow control of certain 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 ["amp", "dsp", "tuner", "tone", "channels", "video", "system", "audio"] 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 Setting to true will disable auto queries on init for all functions apart from basic functionality (power, source, volume and mute). If you only need those functions, you can set this to true
am_frequency_step int null Optional setting to configure the AM frequency step. If this is set to null, a function is queued to detect this information by stepping up and down the frequency when the tuner is first used while set to AM.
debug_listener bool false Enables additional debug logging for the listener task.
debug_responder bool false Enables additional debug logging for the responder 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.

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:

Connection methods

PioneerAVR.__init__(host, port = DEFAULT_PORT, timeout: float = DEFAULT_TIMEOUT, _scaninterval: int = 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 _scaninterval seconds. Optional user parameters are provided via params.

awaitable PioneerAVR.connect(reconnect: bool = True)

Establish a connection to the AVR. Set reconnect to True to attempt to re-establish the connection on disconnect.

awaitable PioneerAVR.disconnect()

Disconnect from the AVR. Attempt to re-establish the connection if enabled.

awaitable PioneerAVR.shutdown()

Permanently disconnect from the AVR. Does not attempt reconnection.

awaitable PioneerAVR.set_timeout(timeout: float)

Set command timeout. Used also to set the socket keepalive timeout.

Update methods

awaitable PioneerAVR.update(full: bool = False, wait: bool = True)

Request an update of the AVR, and wait for the update to complete if wait is True.
If full is True, then a full update is performed irrespective of when the previous update was performed. Otherwise, an update is performed if the scan interval has elapsed.
If a scan interval is set, then an update is scheduled in the updater task. Otherwise the update is performed synchronously (wait cannot be set to False in this case).

awaitable PioneerAVR.set_scan_interval(_scaninterval: int)

Set the scan interval to _scaninterval and restart the updater task.

awaitable PioneerAVR.update_zones()

Update zones from ignored_zones parameter and re-query zones from the AVR.
