# aiomadeavr
A library/utility to control Marantz/Denon devices over the telnet port.
[](https://pypi.python.org/pypi/aiomadeavr)
[](https://lbesson.mit-licen)
[](https://github.com/psf/black)
# Installation
We are on PyPi so
pip3 install aiomadeavr
# Why?
Another project [aio_marantz_avr](https://github.com/silvester747/aio_marantz_avr) targets the
same problem. Unfortunately, it has a few shortcomings for my intended use. For one thing, whilst
it is using asyncio, it is not really asynchronous as you need to poll the device to get data. Second,
there is no automatic discovery of devices.
So I decided to write my own.
Note that I lifted some code from [aio_marantz_avr](https://github.com/silvester747/aio_marantz_avr), but
in the end, it is so far from the original that it made no sense to create this as a PR.
# Running
This has been tested with a Marantz SR7013 receiver.
Although aiomadeavr is meant to be use as a library, the module can be ran, just do
python3 -m aiomadeavr
After a moment, if you type "enter", you should see a list of the device that have been
discovered. You will be able to power the device on/off, mute/unmute it, set the volume, choose
the source and select the surround mode. You will also be able to change the sound channels bias.
# Discovery
There is actually no way to discover the telnet service of those devices. So aiomadeavr cheats.
As far as I can tell all recent Marantz/Denon networked devices support Denon's
[HEOS](https://www.denon.com/en-gb/heos). That service advertises itself over the [Simple Service Discovery Protocol](https://en.wikipedia.org/wiki/Simple_Service_Discovery_Protocol). Discovery looks for those services
and, hopefoolly, the devices we can telnet to will answer the Denon/Marantz serial protocol.
# Documentation
Here are the exposed API functions and object
## avr_factory
This is a coroutine. It is how one creates devices instances.
Parameters are:
name: The friendly name of the instances, a string
addr: The IP asddress, a string
These 2 are required, there are also 2 optional parameters:
port: The port to connect to. An integer. Default is 23
timeout: A timeout,currently not used default 3.0
If anything goes wrong, avr_factory will return None. If things go right, it will return an MDAVR object
## MDAVR
This is the class used to communicate with the device.
When created with avr_factory, the object will connect to the device and start reading the information
coming from the device. It will then issue a list of command to get the current state of the device.
All communications with a device must be performed through a MDAVR instance.
Here are the exposed attributes and method of the MDAVR class.
### String Attr: name
The friendly name of the device. This was passed to avr_factory at creation time.
### Dictionary Attr: status
Current status of the device. Below is a pretty printed example from a marantz SR7013:
Power: On
Main Zone: On
Zone 2: Off
Zone 3: Off
Muted: False

### Float Attr: volume, z2_volume, z3_volume
Current zone volume of the device. From 0.0 to max_volume by 0,5 increments
### Float Attr: max_volume
Maximum of the volume range.
### String Attr: source, z2_source, z3_source
Current source of the device, for instance Bluray, CD, Set Top Box,...
### List Attr: source_list
List of all the possible sources. When setting a source, the name MUST BE in this list.
Not all sources are available to all devices. aiomadeave will try to get the list of inputs available to the device.
### String Attr: sound_mode
Current sound processing mode, for instance: Stereo, DTS, Pure Direct,...
### List Attr: sound_mode_list
List of all the possible sound_mode. When setting a sound_mode, the name MUST BE in this list.
Not all sound_mode are available to all devices.
### String Attr: picture_mode
Current video processing mode, for instance: Custum, Vivid, ISF Day,...
### List Attr: picture_mode_list
List of all the possible picture_mode. When setting a picture_mode, the name MUST BE in this list.
Not all picture_mode are available to all devices.
### String Attr: eco_mode
Current economy mode setting, one of 'On', 'Off' or 'Auto'
### List Attr: eco_mode_list
List of all the possible economy mode settings. When setting the economy mode, the name MUST BE in this list.
Economy mode is not available on all devices.
### Dictionary Attr: channels_bias
The bias for all the currently available channels. The key is the channel name, and the
value is the bias as a float. The bias is between -12 dB and +12 dB
### List Attr: channels_bias_list
List of all the possible channels for which a bias can be set. When setting a channel bias the name MUST BE in this list.
Note that this list is dynamic has it depends on the sound mode. Values are like: Front Right, Surrond Left,...
### Method: refresh
No parameter.
Ask the device to query its current status. Returns None.
### Method: turn_on, main_tunr_on, z2_turn_on, z3_turn_on
No parameter.
Turn on the device/zone. Returns None. 'turn_on' will affect all zones
### Method: turn_off, main_power_off, z2_power_off, z3_poweer_off

func: A callable with 2 parameters:
lbl: The name of the property, a key in status
value: The new value
This function register a callable to be called when one
of the status value changes. For 'Channel Bias' it is called
everytime the channel bias info is received.
## Coroutine start_discovery
One parameter:
addr: The multicast address to use for discovery, by default this is the multicast address for SSDP discovery.
callb: A callable. It is called when and HEOS service is discoverd. The callablew must accept one parameter, a dictionary with the following keys:
ip: ip address of the device
name: friendly name
model: The device model
serial: the device serial number
# Caveat
~~Trying to set the current value will often result in AvrTimeoutError exception.~~
The device will simply not respond to unknown commands and will secretly despise you for it. This makes it difficullt to use timeout on sending to detect disconnection.
The channel bias list may get out of sync when setting the sound mode to 'Auto'. It looks like there is a delay before that information is sent.
# Afterthoughts
The module uses asyncio Streams. I think using protocols may have been a wiser choice.
~~Currently, most of the coroutine of the MDAVR object generate a future and wait for it. Not sure it is a good idea. May be removed in the future. Oh, wait!~~
All that silly use of future has now been cleaned up.
