tellcore-py 1.1.2

Python wrapper for Telldus' home automation library

Python wrapper for Telldus Core

tellcore-py is a Python wrapper for Telldus’ home automation library Telldus Core.

• Documentation: https://tellcore-py.readthedocs.org/

• Official home page: https://github.com/erijo/tellcore-py

• Python package index: https://pypi.python.org/pypi/tellcore-py

Please report any problem as a GitHub issue report.

Features

• Wraps the C-interface with a python interface (with classes and exceptions).

• Automatically frees memory for returned strings.

• Throws an exception (TelldusError) in case a library function returns an error.

• Supports python 3 with automatic handling of strings (i.e. converting between bytes used by the C-library and strings as used by python).

• Takes care of making callbacks from the library thread-safe.

• Unit tested.

• Besides being useful with the regular Python implementation (a.k.a. CPython), it also works with pypy.

• Open source (GPLv3+).

• Works on Linux, Mac OS X and Windows.

Requirements

• Python 2.7, 3.2+ or pypy

• Telldus Core library

Installation

$ pip install tellcore-py

Can also be installed by cloning the GIP repository or downloading the ZIP archive from GitHub and unpacking it. Then change directory to tellcore-py and run:

$ python setup.py install

Users

• Tellprox - A local server to use in place of Telldus Live

• tellive-py - A Python wrapper for Telldus Live

Example

A simple example for adding a new “lamp” device, turning it on and then turning all devices off.

from tellcore.telldus import TelldusCore

core = TelldusCore()
lamp = core.add_device("lamp", "arctech", "selflearning-switch", house=12345, unit=1)
lamp.turn_on()

for device in core.devices():
    device.turn_off()

More examples can be found in the bin directory.

Internals

At the bottom there is the Library class which is a ctypes wrapper and closely matches the API of the underlying Telldus Core library. The library class takes care of freeing memory returned from the base library and converts errors returned to TelldusException. The library class is not intended to be used directly.

Instead, the TelldusCore class provides a more python-ish API on top of the library class. This class is used for e.g. adding new devices, or enumerating the existing devices, sensors and/or controllers. E.g. calling the devices() method returns a list of Device instances. The Device class in turn has methods for turning the device on, off, etc.

Changelog

1.1.2 (2015-06-24)

• Added option to Library to make it possible to select if strings should be decoded or not.

• Made tellcore_tool not decode strings (i.e. convert to unicode) when running under Python 2.x to avoid unicode errors when printing non ascii characters.

1.1.1 (2015-05-01)

• Fixed a bug that made tellcore_tool not work with Python 3.x.

1.1.0 (2014-11-19)

• The callback dispatcher is no longer global, but tied to a Library instance. Applications wishing to use callbacks must now pass an explicit dispatcher instance to the TelldusCore constructor.

1.0.4 (2014-11-05)

• Made last_sent_value return an int instead of string.

1.0.3 (2014-02-02)

• Work around crash in Telldus Core (< v2.1.2) when re-initalizing the library after tdClose.

1.0.2 (2014-01-28)

• Packaging fixes.

1.0.1 (2014-01-26)

• Added AsyncioCallbackDispatcher class for integrating callbacks with the new event loop available in Python 3.4 (asyncio).

• Include tools from bin/ when installing.

1.0.0 (2014-01-09)

• Added high level support for device groups in the form of the new class DeviceGroup.

• More complete documentation.

• Removed the methods process_callback and process_pending_callbacks from TelldusCore. Instead, callback_dispatcher is now a public attribute of TelldusCore and the default callback dispatcher QueuedCallbackDispatcher implements the two methods instead.

0.9.0 (2014-01-03)

• Telldus functions that used to return bool (tdSetName, tdSetProtocol, tdSetModel, tdSetDeviceParameter and tdRemoveDevice) now raise an exception instead of returning False.

• Support for rain- and windsensors.

• Include data type in SensorValue.

0.8.0 (2013-08-11)

• Improved callback handling to simplify integration with different event loops. Parameter conversion is now done in the library code and the adaptation to different event loops is done by a simple callback dispatch class. The default dispatcher (when using TelldusCore) is still done using a queue.

• New documentation for parts of the package. Can be read online at https://tellcore-py.readthedocs.org/.

• Fix problem with strings and python 3 (issue #2).

0.1.0 (2013-06-26)

• First release.
