Using Python to brute force my Infrared remote control for a projector

Question

EDIT: I think I have everything almost working. It is just my second loop keeps having an index failure... any ideas why my coms loop is failing?

I am currently trying to get the IR codes for my HD180x optomoa projector. It is turning into a really difficult problem.

I just need to be able to turn the power ON, nothing else.

I do not have an IR Sensor to capture the codes directly, and have taken it as a challenge to try and do it without one.

So far, it is impossible. I have tried several different approaches to getting the IR codes directly from the remote using a Raspberry Pi with no luck.

My next idea is to use an IR blaster and just cycle through all of the possible IR Power ON codes.

LIRC, which is only Pi IR software has a list of a lot of remotes: http://lirc.sourceforge.net/remotes/

What I would like to try and do is make a python script that just grabs all of the files from that list and then tries all of them. The goal is just to turn the projector on, so I can just let it run for as long as it takes and if it turns on I can find out which on did it.

So my pseudo code is as follows:

download entire remote list.
Index entire remote list. = RLISTINDEX[] 2a. Stop the LIRCD service.
Replace /etc/lirc/lircd.conf with RLISTINDEX[] (move one file at a time) 3a. Start the LIRCD Service (this is so it can
Get "Name" field from remote code files. = RNAME
Get list of all possible codes in remote code files = IRCODE_ARRAY
Run irsend SEND_ONCE RNAME IRCODE_ARRAY[] (cycling through the code array)
Return to step 3.

The issues I am not sure how to do are to harvest the "Name" field and the "codes" fields from the configuration files.

Also, not sure how to send terminal commands through python.

Any ideas?

I was able to get the code to start sending and now I just need to find out how to get the "IR Codes" from the conf files...

Im so close... I just need to be able to do an "irsend list "" "" >> /home/pi/list.ist" so I can find the NAME of the remote that is currently active....... I just cant seem to figure out how to make that command run correctly. I think the quotes are messing it up.....

I got everything working.. here is the code

import os
import shutil
import subprocess
import time

#removes files to start fresh
os.system("touch /home/pi/com.list")
os.system("touch /home/pi/list.list")
os.system("systemctl start lircd")

#gets a sorted list of all the configuration files from LIRC remote storage
for filename in sorted(os.listdir('/home/pi/confs')):
    #gets the first file
    currconf = "/home/pi/confs/" + filename
    print "**********start*******"
    print "1. ", filename

 #moves the first config file to lircd.conf so restart can make it show up
    shutil.move(currconf, "/etc/lirc/lircd.conf")

#restarts lircd (the reset-failed is to make sure there are no time outs
    subprocess.call('systemctl reset-failed lircd', shell=True)
    subprocess.call('systemctl restart lircd', shell=True)
    time.sleep(1)
#shows the status of lircd
    subprocess.call('systemctl status lircd | tail -3', shell=True)

#removes files again to make sure it is fresh
    os.remove("/home/pi/list.list")
    os.remove("/home/pi/com.list")
# sends an iresend to get list of all remotes in the remote configuration file that was used and pits it in list.list to be used for configuration later
    os.system('irsend list "" "" >> /home/pi/list.list')


#opens list.list
    qbfile = open("/home/pi/list.list", "r")
#for all remotes in list.list
    for aline in qbfile:
#this gets the remote names        
        values = aline.split()  
        if values:
            print(values[0])
#removes end of file from remote names
            rname = values[0].strip('
')
            print "2. rname", rname
#creates command that is going to list all commands of given remote names
            comlist = 'irsend list ' + rname + ' "" >> /home/pi/com.list'
            print "3. comlist", comlist
#runs command            
            os.system(comlist)
#opens command list file            
            comfile = open("/home/pi/com.list", "r")
            for coms in comfile:
#gets command name, and not command hex                
                comvalues = coms.split()  

                #makes sure if there is a null value it does not hang the loop
                if comvalues:
                    comand = comvalues[1]#.strip('
')
                    print "4. cmd ", comand
                    time.sleep(.1)

                    command2 = 'irsend SEND_ONCE ' + rname + " " + comand
                    print "5. command2", command2
                    ppp = subprocess.Popen(command2, universal_newlines=True, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
                    text = ppp.stdout.read()
                    retcode = ppp.wait()
                    print text


    print "**********end*******"
