# Control an HEOS player with a Python script

[![PyPI version](https://badge.fury.io/py/heospy.svg)](https://badge.fury.io/py/heospy)

## Requirements

You have an [HEOS][] speaker in your local network and Python 3.

## Usage

0. Install the package with `pip install heospy` (latest published release from
   pypi) or `pip install git+https://github.com/ping13/heospy.git` (if you want
   to use the latest git version). You can also download the source package and
   run `pip install .`.

1. Create a `config.json` file, which may reside in a directory called
   `$HOME/.heospy/` or in a directory wich is specified by the environment
   variable `$HEOSPY_CONF`. You can also specify the config-file directly witgh
   `-c`. The config file contains the name of the lead [HEOS][] player you want
   to control and the username and password of your [HEOS account][]. See
   `example-config.json` for an example.

2. Run the script for the first time to see how this works:

$ heos_player
        2017-02-12 20:32:29,880 INFO Starting to discover your HEOS player 'Living room' in your local network
        2017-02-12 20:32:36,824 INFO Found 'Living room' in your local network
        $
        
3. Now you can call any command from the [CLI specs][specs], see also `docs/`
   folder. Additional arguments are given with `-p`. The player id will be
   automatically submitted. Some examples:

heos_player player/toggle_mute
        heos_player player/set_volume -p level=19
        heos_player player/play_preset -p preset=3
        heos_player player/set_play_state -p state=stop
        heos_player group/toggle_mute
        heos_player group/toggle_mute -p gid=-1352658342

Use the flag `--help` for a detailed help.

## Parsing the response from HEOS

`heos_player` returns a JSON object which directly comes from an HEOS
player. For example:

heos_player player/get_volume
    
gives something like

{
        "heos": {
            "message": "pid=-1352658342&level=13", 
            "command": "player/get_volume", 
            "result": "success"
        }
    }

Unfortunately, HEOS hides some of the results in the `message` property (here:
the volume level of the main player). `heospy` parses the message string and
puts the contained attributes in a seperate property `heos_message_parsed`:

{
       "heos_message_parsed": {
         "pid": "-1352658342", 
         "level": "13"
       }, 
       "heos": {
         "message": "pid=-1352658342&level=13", 
         "command": "player/get_volume", 
         "result": "success"
       }
     }

With [`jq`](https://stedolan.github.io/jq/), you can directly get the result on
the command line:

$ heos_player player/get_volume | jq .heos_message_parsed.level
     "13"

## Main player setting and referencing other players by name

The class `HeosPlayer` assumes a main HEOS player, stored in the config
file. For commands starting with `player/`, we assume that this player should
be used, otherwise you need to specify the player id explicitly as a parameter
`pid`.

You may also specify a player by name by using the fake parameter `pname`: the
class `HeosPlayer` will search for a player with the given name and will try to
translate it to a player id, e.g. with:

$ heos_player player/get_volume -p pname=Küche
      [...]
      2019-01-15 20:04:51,624 INFO Issue command 'player/get_volume' with arguments {"pname": "K\u00fcche"}
      2019-01-15 20:04:51,624 DEBUG translated name 'Küche' to {'pname': 'pid', 'gname': 'gid'}=941891005
      2019-01-15 20:04:51,625 INFO cmd : player/get_volume, args &pid=941891005
      [...]
      {
         "heos_message_parsed": {
           "pid": "941891005", 
           "level": "12"
         }, 
         "heos": {
           "message": "pid=941891005&level=12", 
           "command": "player/get_volume", 
           "result": "success"
         }
       }

If the main player is a lead player in a group, this group is also the main
group for commands starting with `group/`. Again, you can override this setting
be explicitly mention the group id as a parameter. You may also specify the
group by name with a fake parameter `gname`.

## Rudimentary scripting of HEOS commands

You can also execute a sequence of commands at once. The sequence can be given
in a text file:

heos_player -i cmds.txt

An example for `cmds.txt` is:

system/heart_beat
    # let's set a volume level
    player/set_volume level=10
    # let's check if the volume is correct
    player/get_volume

Note that comments are possible and start with a `#`. There is also a special
command `wait`, which waits a number of seconds until the next command is
played.

# play an MP3 file, wait 360 seconds and then turn the mute button on
    player/play_stream pname=Küche url=http://example.com/example.mp3
    wait 360 
    player/set_mute -p state=on

It's a current limitation that `heospy` doesn't listen to events emitted from
any HEOS player.

You can also get the sequence of commands from `stdin`:

printf "system/heart_beat\nplayer/set_volume level=10\nplayer/get_volume" | heos_player -i -

## Example Usage

### Usage with HomeKit

With [Homebridge](https://homebridge.io) and the [Homebridge Script2
plugin](https://github.com/pponce/homebridge-script2), you can bind your
`heospy`-scripts to a HomeKit-button.

Let's assume that you installed HomeBridge via Docker. Set up an environment
variable `HEOSPY_CONF`for the directory of your config file (could be a mounted
directoy). Then add the following to the startup script `start.sh`of the docker
container:

```
# install jq to parse output from heos_player
apk add --no-cache jq openssh sshpass screen

# install heos_player
pip install heospy
# rediscover HEOS devices
heos_player --rediscover
```

Here is an example configuration for an `homebridge-script2`plugin, change the
pid accordingly:

```json
{
    "on": "cat /homebridge/scripts/heos_on.heospy | heos_player heos_config.json -i -",
    "name": "HEOS",
    "on_value": "play",
    "off": "printf 'player/set_play_state pid=-19041904 state=pause' | heos_player -i -",
    "state": "heos_player -l ERROR player/get_play_state pid=-19041904 | jq -r .heos_message_parsed.state",
    "accessory": "Script2"
}
```

Example `heos_on.heospy`-script:

```
group/set_mute gid=-19041904 state=off --ignore-fail
player/set_play_state pid=-1440680417 state=play
group/set_volume gid=-19041904 level=13 --ignore-fail
```

### Usage with Raspberry Pi and Kodi

If you have [OSMC][] or any other [Kodi Media center][Kodi] implementation on
your [Raspberry Pi][raspi], you can map certain actions for your HEOS on a
[keymap][].

[OSMC]: https://osmc.tv
[raspi]: https://www.raspberrypi.org
[Kodi]: http://kodi.wiki/view/Kodi
[keymap]: http://kodi.wiki/view/Keymaps

Example `keyboard.xml`-file:

```xml
<keymap>
<global>
<keyboard>
<F1>RunScript(heos_player, player/play_preset, -p, preset=1)</F1>
<F2>RunScript(heos_player, player/play_preset, -p, preset=2)</F2>
<F3>RunScript(heos_player, player/play_preset, -p, preset=3)</F3>
<F4>RunScript(heos_player, player/play_preset, -p, preset=4)</F4>
<F12>RunScript(heos_player, player/set_play_state, -p, state=stop)</F12>
</keyboard>
</global>
<Home>
</Home>
</keymap>
```

## Limitations

Currently, heospy cannot listen to events from an HEOS player. Events are
described in the [specification][specs]. Please contact me, if you are
interested in helping out.
