A Python-based socket client for Global Cache GC100 digital I/O interface

Project description

python-gc100
=============

This is a Python-based socket client for Global Cache GC100 digital I/O interface

The global cache GC100 features an array of digital inputs / IR outputs (switchable),
serial ports, and solid state relays, accessible via a TCP interface.

More info can be found at the manufaturer's website: https://www.globalcache.com/products/gc-100/

python-gc100 provides a TCP client to interface with a GC100.

Currently serial port communication and IR functions are not supported.
Digital input (including notification mode) and changing relay state are supported.



Usage
-----

Given a callback function

>>> def callback_fn(state):
>>> print(state)

Initialize the connection to the socket server

>>> hostname = 'myserver'
>>> port = 4998
>>> gc = gc100.GC100SocketClient(hostname,port)

Example, if you want to read and print the state of module address '4:1':

>>> gc.read_input('4:1', callback_fn)

Or turn the relay on at address '3:2', and confirm its new state:

>>> gc.write_switch('3:2', 1, callback_fn)

Turn it off again:

>>> gc.write_switch('3:2', 0, callback_fn)

If you want to subscribe to be notified (push) of state changes to digital input '4:3':

>>> gc.subscribe_notify('4:3', callback_fn)

Close the connection

>>> gc.quit()

Compatibility
------------

This module is only tested with Python 3.5.2, and will definitely not be compatible with python 2.x
