Installation

pip install pysnoo

Programmatic Usage

Programatically, the project provides two main class inferfaces. The Snoo API Client interface snoo.py and the Snoo PubNub interface pubnub.py.

Here's a short example to setup both. It uses the Snoo API Interface to get the Snoo serial number, and access token, which are required to initialize the PubNub interface. More usage examples can be found by looking at the CLI Tool or the unit tests.

async with SnooAuthSession(token, token_updater) as auth:

    if not auth.authorized:
        # Init Auth
        new_token = await auth.fetch_token(username, password)
        token_updater(new_token)

    # Snoo API Interface
    snoo = Snoo(auth)
    devices = await snoo.get_devices()
    if not devices:
        # No devices
        print('There is no Snoo connected to that account!')
    else:
        # Snoo PubNub Interface
        pubnub = SnooPubNub(auth.access_token,
                            devices[0].serial_number,
                            f'pn-pysnoo-{devices[0].serial_number}')

        last_activity_state = (await pubnub.history())[0]
        if last_activity_state.state_machine.state == SessionLevel.ONLINE:
            # Start
            await pubnub.publish_start()
        else:
            # Stop
            await pubnub.publish_goto_state(SessionLevel.ONLINE)

        await pubnub.stop()

CLI Usage

The pysnoo package contains the snoo CLI tool:

# snoo -h
Snoo Smart Bassinett

positional arguments:
  {user,device,baby,last_session,status,sessions,session_avg,total,monitor,history,toggle,toggle_hold,up,down}

optional arguments:
  -h, --help            show this help message and exit
  -u USERNAME, --username USERNAME
                        username for Snoo account
  -p PASSWORD, --password PASSWORD
                        username for Snoo account
  -t file, --token_file file
                        Cached token file to read and write an existing OAuth Token to.
  -d DATETIME, --datetime DATETIME
                        Datetime in ISO8601 fromat. Used for some commands.

Credentials / Token / First Run

If the tool cannot find a valid oauth token in --token_file (./.snoo_token.txt by default), it will automatically query for a username and password on the first run. After a successful authentication a token will be placed in the specified file. Subsequent calls that have access to the token will not query for credentials any longer.

# snoo status
Username: [e-mail]
Password: 
awake (since: 0:34:54.891556)
# ls .snoo_token.txt
.snoo_token.txt
# snoo status
awake (since: 0:36:27.266366)
.snoo_token.txt

Snoo CLI Commands

status

snoo status returns the current status of the snoo.

monitor

snoo monitor monitors the live events emited by the Snoo Bassinet. Monitoring can be cancelled via CTRL-C. The command always returns the last historic event when launching.
