Python Device Cloud Library

Be sure to check out the full documentation. A Changelog is also available.

Overview

Python-devicecloud is a library providing simple, intuitive access to Digi Device Cloud(sm) for clients written in Python.

The library wraps Device Cloud's REST API and hides the details of forming HTTP requests in order to gain access to device information, file data, streams, and other features of Device Cloud. The API can be found here.

The primary target audience for this library is individuals interfacing with Device Cloud from the server side or developers writing tools to aid device development. For efficient connectivity from devices, we suggest that you first look at using the Device Cloud Connector. That being said, this library could also be used on devices if deemed suitable.

Example

The library provides access to a wide array of features, but here is a couple quick examples to give you a taste of what the API looks like.

from devicecloud import DeviceCloud

dc = DeviceCloud('user', 'pass')

# show the MAC address of all devices that are currently connected
#
# This is done using Device Cloud DeviceCore functionality
print "== Connected Devices =="
for device in dc.devicecore.get_devices():
    if device.is_connected():
        print device.get_mac()

# get the name and current value of all data streams having values
# with a floating point type
#
# This is done using Device Cloud stream functionality
for stream in dc.streams.get_streams():
    if stream.get_data_type().lower() in ('float', 'double'):
        print "%s -> %s" % (stream.get_stream_id(), stream.get_current_value())

Installation

This library can be installed using pip. Python versions 2.7+ and 3+ are supported by the library.

pip install devicecloud

If you already have an older version of the library installed, you can upgrade to the latest version by doing

pip install --upgrade devicecloud

Supported Features

Eventually, it is hoped that there will be complete feature parity between Device Cloud API and this library. For now, however, that is not the case. The current features are supported by the library:

• Getting basic device information via DeviceCore
• Provision and Delete devices via DeviceCore
• Listing devices associated with a device cloud account
• Interacting with Device Cloud Data Streams
  • Create Streams
  • Get Stream (by id)
  • List all streams
  • Get metadata for a stream
  • Write a single datapoint to a stream
  • Write many datapoints to a stream (homogeneous bulk write)
  • Write many datapoints to multiple streams (heterogeneous bulk write)
  • Read data points from a stream (includes control over order of returned data set as well as allowing for retrieving data roll-ups, etc.)
• Support for accessing Device Cloud FileData store
  • Get filedata matching a provided condition (path, file extension, size, etc.)
  • Write files to filedata store
  • Recursively walk filedata directory tree from some root location
  • Get full metadata and contents of files and directories.
• Low level support for performing basic SCI commands with limited parsing of results and support for only a subset of available services/commands.
• APIs to make direct web service calls to Device Cloud with some details handled by the library (see DeviceCloudConnection and 'ws' documentation)
• Device Provisioning via Mac Address, IMEI or Device ID
• Monitors
• Creating a TCP or HTTP monitor

The following features are not supported at this time. Feedback on which features should be highest priority is always welcome.

• Alarms
• Scheduled Operations
• Asynchronous SCI requests
• High level access to many SCI/RCI operations
• DeviceMetaData
• DeviceVendor
• FileDataHistory
• NetworkInterface support
• XBee specific support (XBeeCore)
• Smart Energy APIs
• SMS Support
• SM/UDP Support
• Carrier Information Access
