# aiomadeavr

A library/utility to control Marantz/Denon devices over the telnet port.

[![PyPI version fury.io](https://badge.fury.io/py/aiomadeavr.svg)](https://pypi.python.org/pypi/aiomadeavr)
[![MIT license](https://img.shields.io/badge/License-MIT-blue.svg)](https://lbesson.mit-licen)
[![GITHUB-BADGE](https://github.com/frawau/aiomadeavr/workflows/black/badge.svg)](https://github.com/psf/black)

**Requires Python 3.11+**

# Installation

We are on PyPi so

    pip3 install aiomadeavr

For the Textual-based TUI (terminal user interface):

    pip3 install aiomadeavr[tui]

# 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 used as a library, it includes a standalone application:

    avrctl

This will start the Textual TUI (if installed) or fall back to the CLI mode.

Note: Can also be run as a module with `python3 -m aiomadeavr`.

## Command Line Options

    avrctl                        # Discovery + TUI (or CLI if Textual not installed)
    avrctl --ip 192.168.1.100     # Direct connection to specific IP
    avrctl --cli                  # Force CLI mode (no Textual)
    avrctl -d                     # Debug mode with log panel
    avrctl -V                     # Show version

## TUI Mode

If you have Textual installed (`pip install aiomadeavr[tui]`), you get a full terminal UI with:
- Device discovery panel
- Status display (power, volume, source, sound mode, etc.)
- Volume control with mute toggle
- Source and sound mode selection
- Zone 2 and Zone 3 controls

Keyboard shortcuts: `q` quit, `r` refresh, `d` discover, `m` mute, `+`/`-` volume

## CLI Mode

In CLI mode, after a moment, if you type "enter", you should see a list of devices 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 commands to get the current state of the device.

All communications with a device must be performed through a MDAVR instance.

MDAVR supports async context managers for clean resource management:

```python
import asyncio
from aiomadeavr import avr_factory

async def main():
    avr = await avr_factory("Living Room", "192.168.1.100")
    if avr:
        async with avr:
            avr.turn_on()
            await asyncio.sleep(2)
            avr.set_volume(35)
        # Connection is automatically closed

asyncio.run(main())
```

Here are the exposed attributes and methods of the MDAVR class.

This function registers a callable to be called when one
of the status values changes. For 'Channel Bias' it is called
every time the channel bias info is received.

### Method: close

No parameter.

Closes the connection to the device. Use this when not using the async context manager.

Returns None.

### Async Method: aclose

No parameter.

Async version of close. Properly waits for the connection to be closed.

Returns None.

## 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 discovered.

The callable 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.
