Simple Python lib for the ISY home automation netapp Supporting a Simple and OO interface

The Goal / design concept is to provide a fast and simple to use interface supporting both object oriented and procedural methods

Also Supports real time cache updating by optionally running a sub-thread subscribing to event stream )

Note: This Lib has grown to the point it needs to be restructured / split up

This is a work in progress ( so expect new features )

see [/bin] (/bin) for more examples

nodes, programs and iay vars can be controlled via objects or call methods.

Get and print the status for the node called "Garage Light"

import ISY
myisy = ISY.Isy(addr="admin", userp="admin, userl="isy")

garage_light = myisy.get_node("Garage Light")

print "Node {:} is {:}".format(garage_light.name, garage_light.formatted)

--

Get an object that represents the node called "Garage Light" and turn it off if it is on

import ISY
myisy = ISY.Isy()

garage_light = myisy.get_node("Garage Light")
if garage_light :
    garage_light.off()

--

Alternately you can obtain a Node's object by indexing a Isy obj my the node name or address

import ISY
myisy = ISY.Isy()
myisy["16 3F E5 1"].off()

or myisy["Garage Light"].off()

on 50% :

garage_light = myisy["Garage Light"]
garage_light.on(128)

or without node device objs

myisy.node_comm("Garage Light", "on", 128)

list all nodes and scenes and their status :

pfmt = "{:<22} {:>12}\t{:<12}{!s:<12}"
print(pfmt.format("Node Name", "Address", "Status", "Enabled"))
print(pfmt.format("---------", "-------", "------", "------"))
for nod in isy :
    if nod.objtype == "scene" :
        print(pfmt.format(nod.name, nod.address, "-", "-", ))
    else :
        print(pfmt.format(nod.name, nod.address, nod.formatted, nod.enabled, ))

--

Callbacks can be set up as easy as

def mycall(*args):
    print "mycall called: "
    for i in args :
        print "arg : ", type(i), i

myisy = ISY.Isy(addr="10.1.1.3", eventupdates=1)
myisy.callback_set("Garage Light", mycall, "my extra args")

or

garage_light = myisy["Garage Light"]
garage_light.set_callback(mycall, "my extra args")

or if your not passing extra arguments you can just :

garage_light = myisy["Garage Light"]
garage_light.set_callback = mycall

Callback will be call for all events relating to the node it is registared to

Callbacks are executed as a part of the event subthread

[This needs to be updated]

• [Using_Isy_Class] (/docs/Using_Isy_Class.txt) This is the main class that used to represent the ISY device iitself

• [Using_IsyNode_Class] (/docs/Using_IsyNode_Class.txt) This class is used to represent and control individual Nodes ( aka: sensors and light switches )

• [Using_IsyVar_Class] (/docs/Using_IsyVar_Class.txt) This class is used to represent varabibles internal to the ISY
