asyncpushbullet

Python versions supported current version on PyPI build status

This is a python library for synchronous and asyncio-based communication with the wonderful Pushbullet service. It allows you to send push notifications to your computer, Android, and iOS devices.

In order to use the API you need an API key that can be obtained here. This is user specific and is used instead of passwords.

This is a fork of the synchronous-only pushbullet.py project from randomchars, which uses the pushbullet namespace. This project uses asyncpushbullet. I have made some changes to the pushbullet package, and you ought to be able to use the regular synchronous functions alongside the asyncio-enabled versions. Over time these have drifter further apart, so if you drop in the asyncpushbullet package in place of an older pushbullet package, you will probably need to make some changes to your code in terms of function names and error handling.

Installation

The easiest way is to just open your favorite terminal and type

pip install asyncpushbullet

Alternatively you can clone this repo and install it with

python setup.py install

Requirements

  • requests: Used in synchronous Pushbullet superclass
  • python-magic: Guesses at filetypes for uploading, optional
  • aiohttp: Foundational to the asyncio-enabled AsyncPushbullet classes
  • tqdm: For some command line scripts
  • pillow: Used in some example GUI code

Usage

Command Line (optional)

The asyncpushbullet package has some scripts that can be run from the command line. One is for sending pushes. Two are for listening for and responding to pushes.

There are several ways to authenticate your Pushbullet.com API key when using the command line:

  1. Set the PUSHBULLET_API_KEY environment variable.
  2. Use the --key command line option and include the key as an argument.
  3. Use the --key-file command line option and point to a text file containing the API key.
  4. Use the --oauth2 flag once to authenticate your command line tools using OAuth2.

Pushing a Note from the Command Line

You can push a note from the command line and specify a title and body.

$ pbpush --title "Hello World" --body "nothing to see"

Uploading and Pushing a File from the Command Line

You can upload and push a file as well.

$ pbpush --file homework.txt --title "Homework" --body "Avoid the dog."

The flags available for the pbpush command line script:

usage: pbpush [-h] [-k KEY] [--key-file KEY_FILE] [--proxy PROXY] [-t TITLE]
              [-b BODY] [-d DEVICE] [--list-devices] [-u URL] [-f FILE]
              [--transfer.sh] [-q] [--oauth2] [--debug] [-v] [--version]

optional arguments:
  -h, --help            show this help message and exit
  -k KEY, --key KEY     Your Pushbullet.com API key
  --key-file KEY_FILE   Text file containing your Pushbullet.com API key
  --proxy PROXY         Optional web proxy
  -t TITLE, --title TITLE
                        Title of your push
  -b BODY, --body BODY  Body of your push (- means read from stdin)
  -d DEVICE, --device DEVICE
                        Destination device nickname
  --list-devices        List registered device names
  -u URL, --url URL     URL of link being pushed
  -f FILE, --file FILE  Pathname to file to push
  --transfer.sh         Use www.transfer.sh website for uploading files (use
                        with --file)
  -q, --quiet           Suppress all output
  --oauth2              Register your command line tool using OAuth2
  --debug               Turn on debug logging
  -v, --verbose         Turn on verbose logging (INFO messages)
  --version             show program's version number and exit

There is also a variant of pbpush called pbtransfer that makes it even faster and easier to send off files using the http://transfer.sh service.

$ pbtransfer somefile.jpg someotherfile.mp4

The flags available for the pbtransfer command line script:

usage: pbtransfer [-h] [-k KEY] [--key-file KEY_FILE] [--proxy PROXY]
                  [-d DEVICE] [--list-devices] [-f FILE] [-q] [--oauth2]
                  [--debug] [-v] [--version]
                  [files [files ...]]

positional arguments:
  files                 Remaining arguments will be files to push

optional arguments:
  -h, --help            show this help message and exit
  -k KEY, --key KEY     Your Pushbullet.com API key
  --key-file KEY_FILE   Text file containing your Pushbullet.com API key

  -v, --verbose         Turn on verbose logging (INFO messages)
  --version             show program's version number and exit

Listening for and Responding to Pushes

You can listen for pushes and respond. To simply echo pushes to the console:

$ pblisten --echo

You can have a script called whenever a push arrives. The --exec flag takes its following arguments as a script to call and any parameters to pass that script. The script will be called with those parameters and with the push (json encoded) sent via stdin.

$ pblisten --exec handle_new_push.sh

You can even have multiple actions listed at one time:

$ pblisten --exec handle_new_push.sh  --exec record_in_log.sh

Your script can respond via its stdout in order to send push(es) back. An example response:

[
    {
        "title" : "Fish Food Served",
        "body" : "Your automated fish feeding gadget has fed your fish. "
     },
     { "title" : "Second push", "body" : "Second body" }
]

Or if you only want to send one push, there is a simpler form for your response:

{ "title" : "title here", "body" : "body here"}

Finally instead of --exec, you can use --exec-simple to skip json altogether. Your script will receive the push via stdin except that the first line will be the title of the push, and the subsequent lines will be the body.

$ pblisten --exec-simple handle_new_push.sh

You can throttle how many pushes are received in a period of time using the --throttle-count and --throttle-seconds flags.

If a device nickname is specified, and there is no device with that nickname, a new device will be created with that nickname.

The flags available for the pblisten command line script:

usage: pblisten [-h] [-k KEY] [--key-file KEY_FILE] [-e] [-x EXEC [EXEC ...]]
                [-s EXEC_SIMPLE [EXEC_SIMPLE ...]]
                [-p EXEC_PYTHON [EXEC_PYTHON ...]] [-t TIMEOUT]
                [--throttle-count THROTTLE_COUNT]
                [--throttle-seconds THROTTLE_SECONDS] [-d DEVICE]
                [--list-devices] [--proxy PROXY] [--debug] [-v] [-q]
                [--oauth2] [--clear-oauth2] [--version]

optional arguments:
  -h, --help            show this help message and exit
  -k KEY, --key KEY     Your Pushbullet.com API key
  --key-file KEY_FILE   Text file containing your Pushbullet.com API key
  -e, --echo            ACTION: Echo push as json to stdout
  -x EXEC [EXEC ...], --exec EXEC [EXEC ...]
                        ACTION: Execute a script to receive push as json via
                        stdin. Your script can write json to stdout to send
                        pushes back. [ { "title" : "Fish Food Served", "body"
                        : "Your automated fish feeding gadget has fed your
                        fish. " }, { "title" : "Second push", "body" : "Second
                        body" } ] Or simpler form for a single push: { "title"
                        : "title here", "body" : "body here"}
  -s EXEC_SIMPLE [EXEC_SIMPLE ...], --exec-simple EXEC_SIMPLE [EXEC_SIMPLE ...]
                        ACTION: Execute a script to receive push in simplified
                        form via stdin. The first line of stdin will be the
                        title, and subsequent lines will be the body. Your
                        script can write lines back to stdout to send a single
                        push back. The first line of stdout will be the title,
                        and subsequent lines will be the body.
  -p EXEC_PYTHON [EXEC_PYTHON ...], --exec-python EXEC_PYTHON [EXEC_PYTHON ...]
                        ACTION: Load the given python file and execute it by
                        calling its on_push(p, pb) function with 2 arguments:
                        the push that was received and a live/connected
                        AsyncPushbullet object with which responses may be
                        sent.
  -t TIMEOUT, --timeout TIMEOUT
                        Timeout in seconds to use for actions being called
                        (default 30).

Authentication

To create an AsyncPushbullet object:

from asyncpushbullet import AsyncPushbullet
pb = AsyncPushbullet(api_key)

If your key is invalid (that is, the Pushbullet API returns a 401), an InvalidKeyError is raised the first time communication is made. To check right away for the validity of your key, you can use the verify_key() or async_verify_key() functions, in synchronous or asynchronous mode as appropriate.

from asyncpushbullet import AsyncPushbullet
...
pb = AsyncPushbullet(api_key)
await pb.async_verify_key()
...
await pb.async_close()

or even better -- this is preferred because it neatly closes sessions using the async with context manager.

from asyncpushbullet import AsyncPushbullet

...

async def _run():
    async with AsyncPushbullet(api_key) as pb:
        # Do stuff

loop.create_task(_run())

Event Loops

AsyncPushbullet expects its async functions to operate on only one event loop. Create a new AsyncPushbullet object if you need to operate on multiple event loops. If you need to close an AsyncPushbullet from another loop or thread, use the close_all_threadsafe().

Using a proxy

When specified, all requests to the API will be made through the proxy.

from asyncpushbullet import AsyncPushbullet
pb = AsyncPushbullet(api_key, proxy="https://user:pass@10.10.1.10:3128/")

Pushing a text note

push = await pb.async_push_note("This is the title", "This is the body")

push is a dictionary containing the data returned by the Pushbullet API.

Pushing an address

Pushing addresses is no longer supported by pushbullet.com and has been dropped in asyncpushbullet.

Pushing a list

Pushing lists is no longer supported by pushbullet.com and has been dropped in asyncpushbullet.

Pushing a link

push = await pb.async_push_link("Cool site", "https://github.com")

Pushing a file

Pushing files is a two part process. First you need to upload the file, and after that you can push it like you would anything else.

async def upload_my_file(pb: AsyncPushbullet, filename: str):
    # The actual upload
    info = await pb.async_upload_file(filename)

    # Push as a file:
    await pb.async_push_file(info["file_name"], info["file_url"], info["file_type"],
                             title="File Arrived!", body="Please enjoy your file")

    # or Push as a link:
    await pb.async_push_link("Link to File Arrived!", info["file_url"], body="Please enjoy your file")

async_upload_file() returns a dictionary containing file_type, file_url and file_name keys, which are the same parameters that async_push_file() requires.

You can also upload a file to the https://transfer.sh service using async_upload_file_to_transfer_sh. The https://transfer.sh service allows file uploads up to 10GB in size, and links last only two weeks.

...
info = await pb.async_upload_file_to_transfer_sh(filename)
...

Working with pushes

You can also view all previous pushes:

pushes = await pb.async_get_pushes()

Pushes is a list containing dictionaries that have push data. You can use this data to dismiss notifications or delete pushes.

latest = pushes[0]

# We already read it, so let's dismiss it
await pb.async_dismiss_push(latest.get("iden"))

# And you can delete it
await pb.async_delete_push(latest.get("iden"))

Both of these raise a PushbulletError if there's an error.

You can also delete all of your pushes (be careful):

await pb.async_delete_pushes()

Pushing to specific devices

So far all our pushes went to all connected devices, but there's a way to limit that.

First we need to get hold of some devices.

# Get all devices that the current user has access to.
devices = await pb.async_get_devices()
print(devices)
# [Device('Motorola Moto G'), Device('N7'), Device('Chrome')]

# Or retrieve a device by its name. Returns None if not found.
motog = await pb.async_get_device(nickname='Motorola Moto G')

We can pass the device to push methods:

push = await pb.async_push_note("Hello world!", "We're using the api.", device=motog)

Creating new devices

Creating a new device is easy too, you only need to specify a name for it. Though you can also specify manufacturer, model and icon too.

coffee = await pb.async_new_device("MyCoffeePotGadget")
# or
motog = await pb.async_new_device("MotoG", manufacturer="Motorola", model="G", icon="android")

Now you can use it like any other device.

Editing devices

You can change the nickname, the manufacturer, model and icon of the device. The new Device object is returned.

coffee = await pb.async_new_device("MyCoffeePotGadget")
coffee2 = await pb.async_edit_device(coffee, manufacturer="Me!")

Deleting devices

Of course, you can also delete devices, even those not added by your code.

await pb.async_remove_device(coffee)

Channels

You can also send pushes to channels. First, create a channel on the Pushbullet website (also make sure to subscribe to that channel). All channels which belong to the current user can be retrieved as follows:

# Get all channels created by the current user
channels = await pb.async_get_channels()
print(channels)
# [Channel('My Channel' 'channel_identifier')]

# Or retrieve a channel by its name. Returns None if not found.
mychannel = await pb.async_get_channel('My Channel')

Then you can send a push to all subscribers of this channel like so:

push = await pb.async_push_note("Hello Channel!", channel=mychannel)

Contacts

Contacts, which are known as "Chats" in Pushbullet's terminilogy, work just like devices:

# Get all chats that the current user has access to.
chats = await pb.async_get_chats()
print(chats)
    # [Chat('Pushbullet Team' < pushbullet - team @ pushbullet.com >:
    # {'active': True,
    #  'created': 1484549777.2763588,
    #  'modified': 1484549777.276366,
    #  'muted': None,
    #  'with': {'email': 'pushbullet-team@pushbullet.com',
    #           'email_normalized': 'pushbullet-team@pushbullet.com',
    #           'iden': 'ujzob6qgcYm',
    #           'image_url': 'https://static.pushbullet.com/google-user/4308fcd45302c1dde28c5d86d7654da31bd32e70e9c28cac4a29d7f35c193e51',
    #           'name': 'Pushbullet Team',
    #           'type': 'user'}})]

# How to access properties
print("Active:", chats[0].active)
print("Email:", chats[0].with_email)

# Or retrieve a chat by its email. Returns None if not found.
peter = await pb.async_get_chat('peter@gmail.com')

Now we can use the chat objects like we did with pb or with the devices.:

push = await pb.async_push_note("Hello world!", "We're using the api.", chat=peter)

Adding new chats

bob = await pb.async_new_chat("Bob", "bob@gmail.com")

Sending SMS messages

The author (Robert Harder) does not have any Android devices, so he has not been able to test the asyncio versions of the sms functions. In theory they should work. :-/

motog = await pb.async_get_device(nickname='Motorola Moto G')
push = await pb.async_push_sms(motog, "+3615555678", "Wowza!")

Sending Ephemerals

The Pushbullet service has ephemeral messages that are not stored and are used for, wait for it, ephemeral or transient messaging such as the universal clipboard functionality. You can send these messages as well.

msg = {"body": "something I copied", "type": "clip"}
await pb.async_push_ephemeral(msg)

msg = {"foobar": "Some control message you use for your IoT devices."}
await pb.async_push_ephemerals(msg)

End-To-End encryption

The End-to-End notes are from the original Pushbullet project.

You activate end-to-end encryption by specifying your encryption key during the construction of the Pushbullet instance:

from pushbullet import Pushbullet

pb = Pushbullet(api_key, "My secret password")

When specified, all sent SMS will be encrypted. Note that the use of end-to-end encryption requires the cryptography package. Since end-to-end encryption is only supported for SMS at the moment, the cryptography library is not specified as a dependency of pushbullet.py and should be installed seperatly by running pip install cryptography.

Note that Pushbullet supportes End-To-End encryption only in SMS, notification mirroring and universal copy & paste. Your pushes will not be end-to-end encrypted.

Error checking

If the Pushbullet api returns an error code an __ InvalidKeyError or a PushbulletError is raised. The first __ two are both subclasses of PushbulletError

The pushbullet api documetation contains a list of possible status codes.

Listening for Pushes

To listen for pushes, use the LiveStreamListener class in an async for loop:

async def _run():
    async with AsyncPushbullet(api_key) as pb:
        async with LiveStreamListener(pb) as pl:
            print("Awaiting pushes...")
            async for push in pl:
                print("Got a push:", push)

loop = asyncio.get_event_loop()
loop.run_until_complete(_run())
