Platypush

Execute any command or custom complex logic on your devices, wherever they are, using your PushBullet account.

Installation

pip install platypush

Manual Installation

git clone https://github.com/BlackLight/platypush
cd platypush
python setup.py install

Configuration

Copy /etc/platypush/config.example.yaml to /etc/platypush/config.yaml (system-wise settings) or ~/.config/platypush/config.yaml (user-wise settings).

Edit the file to include:

For the PushBullet backend

• Your PushBullet access token (create one here);
• The name of the (virtual) PushBullet device used to listen for events (create one here).

For the Apache Kafka backend

• The host and port of the Kafka installation
• The topic that will be used to deliver and process messages

For the local socket backend

• The name of the local FIFO that will be used to deliver and process messages

device_id

Each target device is identified by a unique device_id in the messages sent over your account. The device_id is the hostname by default, unless changed in config.yaml.

Shell interface

platypush installs pusher, a command-line tool to send PushBullet messages to the connected devices in the format used by platypush.

Some examples:

pusher --target laptop --action shell.exec --cmd "scp /home/user/photos/*.jpg backup_host:/mnt/hd/photos"
pusher --target raspberrypi --action music.mpd.play

The logic to execute is specified by the --action option, whose format is package_name.method_name (with method_name part of the package main class).

Available plugins

• platypush.plugins.shell: The simplest and yet most versatile plugin. Executes a remote command on the host identified by the --target device_id. Example:

pusher --target laptop --action shell.exec --cmd "scp /home/user/photos/*.jpg backup_host:/mnt/hd/photos"

• platypush.plugins.music.mpd: Controls the playback on a mpd/mopidy music server. Requires the package mpd2 on the target machine. Example:

pusher --target raspberry --action music.mpd.play

Configure the plugin through an entry like this in your config.yaml:

music.mpd:
    host: your_mpd_host
    port: 6600

• platypush.plugins.switch.wemo: Controls a WeMo Switch smart switch device. Requires the package ouimeaux on the target machine. Example:

pusher --target raspberry --action switch.wemo.on

• platypush.plugins.light.hue: Controls a Philips Hue smart lights system. Requires the package phue on the target machine. Example:

pusher --target raspberry --action light.hue.scene --name "Sunset" --group "Living Room"

Writing your plugins

Writing your own platypush plugin, that would execute your own custom logic whenever a bullet with your plugin name is received, is a very simple task.

1. Create your plugin directory under platypush/plugins (e.g. light/batsignal).

2. In the case above, platypush.plugins.light.batsignal will be your package name.

3. Create an __init__.py under platypush/plugins/light/batsignal.

4. If your module is light/batsignal, then its main class should be named LightBatsignalPlugin.

5. The configuration for your module will be read from a section named light.batsignal from your config.yaml, the attributes are accessible in your class in self.config.

The __init__.py will look like this:

import batman

from platypush.response import Response

from .. import LightPlugin

class LightBatsignalPlugin(LightPlugin):
    def _init(self):
        self.batsignal = batman.Batsignal(self.config['intensity'])

    def on(self, urgent=False):
        if urgent:
            self.batsignal.notify_robin()

        self.batsignal.on()
        return Response('ok')

    def off(self):
        self.batsignal.off()
        return Response('ok')

    def toggle(self):
        self.batsignal.toggle()
        return Response('ok')

6. Rebuild and reinstall platypush if required and relaunch it.

7. Test your new plugin by sending some bullets to it:

pusher --target your_pc --action light.batsignal.on --urgent 1
