Platypush is a general-purpose extensible platform for automation and
integration across multiple services and devices.

It enables users to create their own self-hosted pieces of automation based on
events (*if this happens then do that*)
and it provides a comprehensive and customizable user interface that collects
everything you need to visualize and control under one roof.

It takes some concepts from [IFTTT](https://ifttt.com),
[Tasker](https://tasker.joaoapps.com/), [Microsoft
Flow](https://flow.microsoft.com), [PushBullet](https://pushbullet.com) and
[Home Assistant](https://www.home-assistant.io/) to provide an environment
where the user can easily connect things together.

Its ideal home is a single-board computer like a RaspberryPi that you can
configure to orchestrate any home automation and cloud automation in your own
living room or garage, but it can easily run on any device that can run a
Python interpreter, and the bar for the hardware requirements is very low as
well - I use it to run pieces of automation on devices as powerful as a
RaspberryPi Zero or an old Nokia N900 with Linux.

You can use Platypush to do things like:

- [Control your smart home lights](https://blog.platypush.tech/article/Ultimate-self-hosted-automation-with-Platypush)
- [Control your music and synchronize it to multiple devices](https://blog.platypush.tech/article/Build-your-open-source-multi-room-and-multi-provider-sound-server-with-Platypush-Mopidy-and-Snapcast)

## Architecture

The architecture of Platypush consists of a few simple pieces, orchestrated by
a configuration file stored by default under
[`~/.config/platypush/config.yaml`](https://git.platypush.tech/platypush/platypush/-/blob/master/examples/conf/config.yaml):

### Plugins

[Full list](https://docs.platypush.tech/en/latest/plugins.html)

Plugins are integrations that do things - like [modify
files](https://docs.platypush.tech/en/latest/platypush/plugins/file.html),
[train and evaluate machine learning
models](https://docs.platypush.tech/en/latest/platypush/plugins/tensorflow.html),
[control
cameras](https://docs.platypush.tech/en/latest/platypush/plugins/camera.pi.html),
[read
sensors](https://docs.platypush.tech/en/latest/platypush/plugins/gpio.sensor.dht.html),
[parse a web
page](https://docs.platypush.tech/en/latest/platypush/plugins/http.webpage.html),
[control
lights](https://docs.platypush.tech/en/latest/platypush/plugins/light.hue.html),
[send
emails](https://docs.platypush.tech/en/latest/platypush/plugins/mail.smtp.html),
[control
Chromecasts](https://docs.platypush.tech/en/latest/platypush/plugins/media.chromecast.html),
[run voice
queries](https://docs.platypush.tech/en/latest/platypush/plugins/assistant.google.html),
[handle torrent
transfers](https://docs.platypush.tech/en/latest/platypush/plugins/torrent.html)
or control
[Zigbee](https://docs.platypush.tech/en/latest/platypush/plugins/zigbee.mqtt.html)
or [Z-Wave](https://docs.platypush.tech/en/latest/platypush/plugins/zwave.html)
devices.

The configuration of a plugin matches one-on-one that of its documented class
constructor, so it's very straightforward to write a configuration for a plugin
by reading its documentation:

```yaml
light.hue:
  # Groups that will be controlled by default
  groups:
    - Living Room
    - Hall
```

### Actions

Plugins expose *actions*, that match one-on-one the plugin class methods
denoted by `@action`, so it's very straightforward to invoke plugin actions by
just reading the plugin documentation. They can be invoked directly from your
own scripts or they can be sent to the platform through any supported channel
as simple JSON messages:

```json
{
  "type": "request",
  "action": "light.hue.on",
  "args": {
    "lights": ["Entrance Bulb"]
  }
}
```

### Backends

[Full list](https://docs.platypush.tech/en/latest/backends.html)

They are background services that either listen for messages on channels (like
an [HTTP
backend](https://docs.platypush.tech/en/latest/platypush/backend/http.html), an
[MQTT
instance](https://docs.platypush.tech/en/latest/platypush/backend/mqtt.html), a
[Kafka
instance](https://docs.platypush.tech/en/latest/platypush/backend/kafka.html),
a [Websocket
service](https://docs.platypush.tech/en/latest/platypush/backend/websocket.html),
[Pushbullet](https://docs.platypush.tech/en/latest/platypush/backend/pushbullet.html)
etc.) or monitor a device or a service for events (like a
[sensor](https://docs.platypush.tech/en/latest/platypush/backend/sensor.html),
a custom [voice
assistant](https://docs.platypush.tech/en/latest/platypush/backend/assistant.google.html),
a bridge running on a
[Zigbee](https://docs.platypush.tech/en/latest/platypush/backend/zigbee.mqtt.html)
or
[Z-Wave](https://docs.platypush.tech/en/latest/platypush/backend/zwave.html),
an [NFC card
reader](https://docs.platypush.tech/en/latest/platypush/backend/nfc.html), a
[MIDI
device](https://docs.platypush.tech/en/latest/platypush/backend/midi.html), a
[Telegram
channel](https://docs.platypush.tech/en/latest/platypush/backend/chat.telegram.html),
a [Bluetooth
scanner](https://docs.platypush.tech/en/latest/platypush/backend/bluetooth.scanner.ble.html)
etc.).

If a backend supports the execution of requests (e.g. HTTP, MQTT, Kafka,
Websocket and TCP) then you can send requests to these services in JSON format.
For example, in the case of the HTTP backend:

```shell
    # Get a token
curl -XPOST -H 'Content-Type: application/json' -d '
  {
    "username": "$YOUR_USER",
    "password": "$YOUR_PASSWORD"
  }' http://host:8008/auth

    # Execute a request

curl -XPOST -H 'Content-Type: application/json' \
    -H "Authorization: Bearer $YOUR_TOKEN" -d '
  {
    "type": "request",
    "action": "tts.say",
    "args": {
      "text": "This is a test"
    }
  }' http://host:8008/execute
```

### Events

[Full list](https://docs.platypush.tech/en/latest/events.html)

When a certain event occurs (e.g. a JSON request is received, or a [Bluetooth
device is
connected](https://docs.platypush.tech/en/latest/platypush/events/bluetooth.html#platypush.message.event.bluetooth.BluetoothDeviceConnectedEvent),
or a [Flic button is
pressed](https://docs.platypush.tech/en/latest/platypush/events/button.flic.html#platypush.message.event.button.flic.FlicButtonEvent),
or some [speech is detected on the voice assistant
service](https://docs.platypush.tech/en/latest/platypush/events/assistant.html#platypush.message.event.assistant.SpeechRecognizedEvent),
or an [RSS feed has new
items](https://docs.platypush.tech/en/latest/platypush/events/http.rss.html#platypush.message.event.http.rss.NewFeedEvent),
or a [new email is
received](https://docs.platypush.tech/en/latest/platypush/events/mail.html#platypush.message.event.mail.MailReceivedEvent),
or a [new track is
played](https://docs.platypush.tech/en/latest/platypush/events/music.html#platypush.message.event.music.NewPlayingTrackEvent),
or an [NFC tag is
detected](https://docs.platypush.tech/en/latest/platypush/events/nfc.html#platypush.message.event.nfc.NFCTagDetectedEvent),
or [new sensor data is
available](https://docs.platypush.tech/en/latest/platypush/events/sensor.html#platypush.message.event.sensor.SensorDataChangeEvent),
or [a value of a Zigbee device
changes](https://docs.platypush.tech/en/latest/platypush/events/zigbee.mqtt.html#platypush.message.event.zigbee.mqtt.ZigbeeMqttDevicePropertySetEvent),
etc.), the associated backend will trigger an
[event](https://docs.platypush.tech/en/latest/events.html).

### Hooks

Event hooks are custom pieces of logic that will be run when a certain event is
triggered. Hooks are the glue that connects events to actions, exposing a
paradigm similar to IFTTT (_if a certain event happens then run these
actions_). They can declared as:

- Sections of the [`config.yaml`](https://git.platypush.tech/platypush/platypush/-/blob/master/examples/conf/config.yaml).
  Example:

```yaml
event.hook.SearchSongVoiceCommand:
  if:
    type: platypush.message.event.assistant.SpeechRecognizedEvent
    phrase: "play ${title} by ${artist}"
  then:
    - action: music.mpd.clear
    - action: music.mpd.search
      args:
        filter:
          artist: ${artist}
          title: ${title}

    - if ${len(output)}:
      - action: music.mpd.play
        args:
          resource: ${output[0]['file']}
```

- Stand-alone Python scripts stored under `~/.config/platypush/scripts` and
  will be dynamically imported at start time.
  [Example](https://git.platypush.tech/platypush/platypush/-/blob/master/examples/conf/hook.py):

```python
from platypush.event.hook import hook
from platypush.utils import run
from platypush.message.event.assistant import SpeechRecognizedEvent

@hook(SpeechRecognizedEvent, phrase='play ${title} by ${artist}')
def on_music_play_command(event, title=None, artist=None, **context):
  results = run('music.mpd.search', filter={
    'artist': artist,
    'title': title,
  })

  if results:
    run('music.mpd.play', results[0]['file'])
```

### Procedures

Procedures are pieces of custom logic that can be executed as atomic actions
using `procedure.<name>` as an action name.

They can be defined either in the `config.yaml` or as Python scripts stored
under `~/.config/platypush/scripts` - provided that the procedure is also
imported in `~/.config/platypush/scripts/__init__.py` so it can be discovered
by the service.

YAML example for a procedure that can be executed when we arrive home and turns
on the lights if the luminosity is lower that a certain thresholds, says a
welcome home message using the TTS engine and starts playing the music:

```yaml
procedure.at_home:
    # Get luminosity data from a sensor - e.g. LTR559
    - action: gpio.sensor.ltr559.get_data

    # If it's lower than a certain threshold, turn on the lights
    - if ${int(light or 0) < 110}:
        - action: light.hue.on

    # Say a welcome home message
    - action: tts.google.say
      args:
        text: Welcome home

    # Play the music
    - action: music.mpd.play
```

Python example:

```python
    # Content of ~/.config/platypush/scripts/home.py
from platypush.procedure import procedure
from platypush.utils import run

@procedure
def at_home(**context):
  sensor_data = run('gpio.sensor.ltr559.get_data')
  if sensor_data['light'] < 110:
    run('light.hue.on')

  run('tts.google.say', text='Welcome home')
  run('music.mpd.play')
```

In either case, you can easily trigger the at-home procedure by sending an
action request message to a backend - for example, over the HTTP backend:

```shell
curl -XPOST -H 'Content-Type: application/json' \
    -H "Authorization: Bearer $YOUR_TOKEN" -d '
  {
    "type": "request",
    "action": "procedure.at_home"
  }' http://host:8008/execute
```

### Cronjobs

Cronjobs are pieces of logic that will be run at regular intervals, expressed
in crontab-compatible syntax. They can be defined either in the `config.yaml`
or as Python scripts stored under `~/.config/platypush/scripts` as functions
labelled by the `@cron` decorator.

Note that seconds are also supported (unlike the standard crontab definition),
but, for back-compatibility with the standard crontab format, they are at the
end of the cron expression, so the expression is actually in the format
`<minute> <hour> <day_of_month> <month> <day_of_week> <second>`.

YAML example for a cronjob that is executed every 30 seconds and checks if a
Bluetooth device is nearby:

```yaml
cron.check_bt_device:
  cron_expression: '* * * * * */30'
  actions:
    - action: bluetooth.lookup_name
      args:
        addr: XX:XX:XX:XX:XX:XX

    - if ${name}:
        - action: procedure.on_device_on
    - else:
        - action: procedure.on_device_off
```

Python example:

```python
    # Content of ~/.config/platypush/scripts/bt_cron.py
from platypush.cron import cron
from platypush.utils import run

@cron('* * * * * */30')
def check_bt_device(**context):
  name = run('bluetooth.lookup_name').get('name')
  if name:
    # on_device_on logic here
  else:
    # on_device_off logic here
```

### The web interface

If
[`backend.http`](https://docs.platypush.tech/en/latest/platypush/backend/http.html)
is enabled then a web interface will be provided by default on
`http://host:8008/`. Besides using the `/execute` endpoint for running
requests, the built-in web server also provides a full-featured interface that
groups together the controls for most of the plugins - e.g. sensors, switches,
music controls and search, media library and torrent management, lights,
Zigbee/Z-Wave devices and so on. The UI is responsive and mobile-friendly.

The web service also provides means for the user to create [custom
dashboards](https://git.platypush.tech/platypush/platypush/-/blob/master/examples/conf/dashboard.xml)
that can be used to show information from multiple sources on a large screen.

## Installation

### System installation

Platypush uses Redis to deliver and store requests and temporary messages:

```yaml
    # Example for Debian-based distributions
[sudo] apt-get install redis-server

    # Enable and start the service
[sudo] systemctl enable redis
[sudo] systemctl start redis
```

#### Install through `pip`

```shell
[sudo] pip3 install platypush
```

#### Install through a system package manager

Note: currently only Arch Linux and derived distributions are supported.

You can either install the
[`platypush`](https://aur.archlinux.org/packages/platypush) package (for the
latest stable version) or the
[`platypush-git`](https://aur.archlinux.org/packages/platypush-git) package
(for the latest git version) through your favourite AUR package manager. For
example, using `yay`:

```shell
yay platypush
# Or
yay platypush-git
```

The Arch Linux packages on AUR are automatically updated upon new git commits
or tags.

#### Install from sources

```shell
git clone https://git.platypush.tech/platypush/platypush.git
cd platypush
[sudo] pip install .
    # Or
[sudo] python3 setup.py install
```

### Installing the dependencies for your extensions

After installing the base platform, you may want to check the dependencies and
configuration required by the extensions that you wish to use. There are a few
ways to check the dependencies required by an extension:

#### Install via `extras` name

All the extensions that require extra dependencies are listed in the
[`extras_require` section under
`setup.py`](https://git.platypush.tech/platypush/platypush/-/blob/master/setup.py#L72).

#### Install via `manifest.yaml`

All the plugins and backends have a `manifest.yaml` file in their source folder.
Any extra dependencies are listed there

If you followed the `extras` or `manifest.yaml` way to discover the
dependencies, then you can install them in two ways:

1. `pip` installation:

```shell
[sudo] pip3 install 'platypush[extra1,extra2,extra3]'
```

2. Sources installation:

```shell
cd $DIR_TO_PLATYPUSH
[sudo] pip3 install '.[extra1,extra2,extra3]'
```

#### Check the instructions reported in the documentation

If you follow this route then simply run the commands listed in the
[plugin/backend documentation](https://docs.platypush.tech) to get the
dependencies installed.

After installing the dependencies, create a configuration file under
`~/.config/platypush/config.yaml` (the application can load the configuration
from another location through the `-c` option) containing the configuration of
the backend and plugins that you want to use, and add any hooks and procedures
for your use case.

You can then start the service by simply running:

```shell
platypush
```

It's advised to run it as a systemd service though - simply copy the provided
[`.service`
file](https://git.platypush.tech/platypush/platypush/-/blob/master/examples/systemd/platypush.service)
to `~/.config/systemd/user`, check if the path of `platypush` matches the path
where it's installed on your system, and start the service via `systemctl`:

```shell
systemctl --user start platypush
```

### Virtual environment installation

Platypush provides a script named `platyvenv` that can parse a `config.yaml`
and automatically create a virtual environment (under
`~/.local/share/platypush/venv/<device_id>`) with all the dependencies required
by the configured integrations.

1. Create the environment from a configuration file:

    ```shell
    platyvenv build -c /path/to/config.yaml
    ```

2. Start the service from the virtual environment:

    ```shell
        # device_id matches either the hostname or the device_id in config.yaml
    platyvenv start device_id
    ```

3. Stop the instance:

    ```shell
    platyvenv stop device_id
    ```

4. Remove the instance:

    ```shell
    platyvenv rm device_id
    ```

[Wiki instructions](https://git.platypush.tech/platypush/platypush/wiki/Run-platypush-in-a-virtual-environment)

### Docker installation

You can also install Platypush in a container - the application provides a
script named `platydock` that automatically creates a container instance from a
`config.yaml`:

1. Create the container from a configuration file:

    ```shell
    platydock build -c /path/to/config.yaml
    ```

2. Start the container:

    ```shell
        # device_id matches either the hostname or the device_id in config.yaml
    platydock start device_id
    ```

3. Stop the instance:

    ```shell
    platydock stop device_id
    ```

4. Remove the instance:

    ```shell
    platydock rm device_id
    ```

Note that both the virtual environment and Docker container option offer the
possibility to include extra YAML configuration files in the main `config.yaml`
through the `include` directive (as long as they are in the same folder as the
main `config.yaml`), as well as external Python scripts in a `scripts`
directory in the same folder as the `config.yaml`.

[Wiki instructions](https://git.platypush.tech/platypush/platypush/wiki/Run-platypush-in-a-container)

## Mobile app

An [official Android
app](https://f-droid.org/en/packages/tech.platypush.platypush/) is provided on
the F-Droid store. It allows to easily discover and manage multiple Platypush
services on a network through the web interface, and it easily brings the power
of Platypush to your fingertips.

## Tests

To run the tests simply run `pytest` either from the project root folder or the
`tests/` folder. Or run the following command from the project root folder:

```shell
python -m tests
```
