Building an IR Blaster
-
So about half of this topic got cut off. To catch people up: The main goal of this topic is to create an IR transmitter device in Vera that can be used to send IR codes to a TV, DVD, DVR, etc. The transmitter is easy to assemble by attaching an IR LED and IR receiver (for learning codes) to an Arduino. The cost of this is about $15. Normal IR blasters range from $50 (USB UIRT - not wireless) to over $100 (Global Cache WF2IR - wireless). Seeing that I could save $85, a MySensors IR blaster looked great.
When trying to connect the IR blaster to Vera, and get it to transmit, I encountered some problems. The MySensors program currently does not support IR blasters, so I tried to edit the code and make it work. After looking at the SQ Blaster plugin, it gave me an idea of how to get the IR blaster to work. I edited lump files in an attempt to create an IR blaster device. I have so far been able to have Vera create an IR blaster device that shows up on the devices page.
However, when trying to use it to create an IR device (TV) I can go through the initial setup
But then click on any of the remote's buttons gets me this error message.
I have been stuck with this for a while now. Also, the Vera appears to be sending the IR command:
08 06/06/14 10:25:29.361 JobHandler_LuaUPnP::HandleActionRequest argument ProntoCode=0000 0071 0000 001A 0080 0080 0020 0020 0020 0020 0020 0020 0020 0060 0020 0020 0020 0060 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0060 0020 0060 0020 0060 0020 0060 0020 0020 0020 0060 0020 0020 0020 0060 0020 0060 0020 0060 0020 0060 0020 0060 0020 0020 0020 04DF <0x2ca29680>

But the IR code never arrives at the Arduino. I am currently trying to fix this problem, and was wondering if anyone could help. Hek suggested I send guessed (from Vera forums) a message which I will do.If any one wants to give this a try, here are the files to upload and test: Please let me know if you see something wrong with the code!
L_Arduino.lua
Which contains:
function sendProntoCode(prontoCode, device)
sendCommand(luup.devices[device].id,"IR_SEND",prontoCode)
endI_Arduino1.xml
Which contains:
<action>
<serviceId>urn:micasaverde-com:serviceId:IrTransmitter1</serviceId>
<name>SendProntoCode</name>
<run>sendProntoCode(lul_settings.ProntoCode, lul_device)</run>
</action>D_Arduino1.xml
Which contains:
<service>
<serviceType>urn:schemas-micasaverde-com:service:IrTransmitter:1</serviceType>
<serviceId>urn:micasaverde-com:serviceId:IrTransmitter1</serviceId>
<SCPDURL>S_IrTransmitter1.xml</SCPDURL>
</service>MySensors_IR.ino
Which creates the IR device (S_IR) and then serial prints whatever message it receives.Quick side note:There are two IR codes that Vera might be sending right now. A short code, 0x2ca29680 (in Vera log), or 0000 0071 0000 001A 0080 0080 0020 0020 0020 0020 0020 0020 0020 0060 0020 0020 0020 0060 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0060 0020 0060 0020 0060 0020 0060 0020 0020 0020 0060 0020 0020 0020 0060 0020 0060 0020 0060 0020 0060 0020 0060 0020 0020 0020 04DF (also in Vera log). In the event that Vera is sending the longer code which is too big to send over the air, my solution to that was to have Vera send a single digit representing a longer IR code to send, for example 1 = power button, 2 = volume up, 3 = volume down, etc. The single digit method is already in the Arduino program so that I can change the IR codes on the Arduino easily without needing to change them in Vera.
Let me know if you have any questions. Thanks for your help!

How were you thinking to get Vera to use that shorter code?
Or asked another way - where does Vera find the PRONTO codes it sends? Can you edit some file to get it to send a short code instead?
As for what code to send to the IR blasting node. You are sending the IR library's 32 bit (or less) interpreted code when there is one.
When there isn't one, I think your approach of saving the raw values to PROGMEM should work well; you can also also save the 32 bit hash the IR library creates. Suggestion: send that hash from Vera, have the node look it up in your PROGMEM and send the corresponding raw values. That is, use the hash rather than sending an arbitrarily assigned digit.
xUnless you have a lot of buttons, and they create long raw codes, you can probably fit them into PROGMEM without needing an SD card.

Thanks! @Zeph
When you create an IR device in Vera, it uses two files:
D_Codeset_2.xml and I_Codeset_2.xml.
You can change the codes in the I_Codeset file to whatever you want (I think). The codes in the I_Codeset file would be the shorter code representing a longer one in the Arduino program.What I still have to figure out is if Vera sends short codes (0x153) or the RAW codes. I'm hoping raw so I can change the code send to different numbers. And if Vera does send pronto codes, I wonder if Vera will try and convert the single digits (representing a larger command) into a pronto code (I doubt it).

@Dringie No... I've been trying to get it to work, but I am still having issues getting Vera to send IR commands to the Arduino. I think it's the implementation of the actual command that send the IR info to the arduino.
I will keep working, and I will send guessed another message.

This looks like a great idea!!
I wish I knew enough of this stuff to help out... I will start building over the weekend with the stuff I have collected, and maybe I might learn some stuff that I can use to help get this project working :-)
fingers crossed lol

I was also planning to make an arduino based IR blaster , since I thought it would be working.
I just want to switch off my mediabox , with that I allready would be happy , when I read this post it is not possible :-S , or do I interpret it wrong?
Thanks,

Very much possible to solve if it's just a few things you want to control. The MySensors provided example creates a "lightswitch" device which triggers ir-sending of a couple of ir codes.
Not a full fledged blaster but it should be enough to solve your particular problem.
