I thought I'd contribute this to the community since it took me a little while to figure out how to get this right. It shows how to send a command to an iTach CC and how to handle the return values using sockets in python. It can get tighter/cleaner, but I left it very basic so it's easier for people to play with.

#!/usr/bin/python

import socket

HOST2 = '192.168.1.201'

PORT2 = 4998

s = socket.socket( socket.AF_INET, socket.SOCK_STREAM)

s.connect((HOST2, PORT2))

s.sendall("setstate,1:2,0\r")

response = s.recv(24) #This is the echo back from iTach

print "Response from send():", response

s.sendall("getstate,1:2\r")

state = s.recv(24)

if ( int(state[10:11]) == 1 ):

  print "Current state is ON"

elif ( int(state[10:11]) == 0 ):

  print "Current state is OFF"

else:

  print "Unknown. Got:", state

  Ted!!!

  Thank you for this. I have been messing with shell commands and perl scripts and nothing has been working... the iTach doesn't get or execute the commands. Finally something that works!

  Now I have no experience with python... but I'd really like to know "why" it works. I am guessing it is some kind of timing issue from the time the socket is opened to when the command string is sent. Gotta figure the magic is in 

  s = socket.socket( socket.AF_INET, socket.SOCK_STREAM)

  is the socket closed at the end of the script? Can multiple sends be done before that happens?

   

  Thanks again,

  hi, thank you for the Python example. Just what I'm looking for to get started.

  I am completely new to this. Will this work with only the flex? I have the WF2IR

  I've tried this from my raspberry pie, and is returning an error.

   

  Your help is greatly appreciated :-)

  Works great here with a IP2IR!

  good to know. I'm running it the straight copy paste from my PC. I'm having a bit of a hard time figuring out the error code. It seems to be written a bit differently than what is in the API. Can you help me make sense of this?

   

  ('Response from send():', 'ERR_0:0,001\r')
  ('Unknown. Got:', 'ERR_1:2,018\r')

   

  Thank you

  WF2IR have no relays to set or query.

  I have been able to get a Python3 piece of code working on my Wifi2IP device and thought someone else might use it:

  #!/usr/bin/python

  import socket

  HOST2 = '192.168.1.20'  #change this to your device

  PORT2 = 4998

  s = socket.socket( socket.AF_INET, socket.SOCK_STREAM)

  s.connect((HOST2, PORT2))

  s.sendall("<YOUR SENDIR OR WHATEVER>\r".encode()) #you need the backslash r at the end for carriage return
  response = s.recv(24) #This is the echo back from iTach
  print ("Response from send():", response)
