💬 Infrared Sender and Receiver
-
That node is simply IR to gateway (or vice versa) transfering medium. It doesn't learn just decodes or emits IR signals. This node is mostly dumb.
To make it learn something like z-wave ir extender,
Manually: Just manually decode and note down required codes then use them. Easy solution for known and used commands like on/off, vol +/-, numbers etc.
- hard code it on node, however program space is tight. eeprom may be required.
- hard code it on controller, easy for logic operations and automation needs.
Automatic:
- Write the code to learn and save it to eeprom. It requires some coding, at the end it might be a device like somehow z-wave ir extender. Howeer controller should know and send some kind of message to select right IR code. I didn't work on this solution yet.

@Talat-Keleş
I am confused . i just want know if i want control my TV ( each switch for example on , off , vol + , vol - , number etc) with a domoticz and a IR sensor (mysensors) how i do it ?Below is node sketch (v1.5.4) and openhab sitemap&items for simple control. More advanced control needs rules/scripts to make it more automation like.
Set up the circuit, load below code or example code given and open serial monitor. Press buttons on IR remote and read hex values on serial. Note down values for buttons you need. (i.e. power off 0x184C, power on 0x104C, chanel up 0x1860 etc, RC5 protocol) If below sketch is uploaded to node, then adapt domoticz to send needed IR codes like i did in sitemaps part or use automation rules to send required commands to node to tv.
Here is my node sketch:

thank you my friend -
is it possible to use with domoticz?

this module ( ir transmitter ) is weak in transmit . for more than 2 or 3 meter distance dont work . also for less than 1 meter we must direct connection exactly.
i think this is related to power or noise or problem of module ?!
can you guidance me ?@Reza said:

can you guidance me ?I'm thinking of building this but am concerned about limited range. I'd like it to work 10ft/3m. Can someone confirm that this does not work at these distances? If so, is there a way to increase the range?

So how can is set this node in learnmode?? V_IR_RECORD in the Serial of Arduino?
How do i store codes in the Eprom. SO i can use them in Domoticz -
I send command from remote control arduino read this command (i can see this in serial monitor) but this commands are not sending to gateway, my radio is working the sensor connect to gateway and controller. I use example Sketch given up in this page without changing anything.
Any idea whats wrong in my setup? -
@Reza said:
is this a learning mode module ?
how use this module for learn my ir codes ?This node decodes IR remote codes, print protocol and hex value to serial monitor and send it to gateway. Then controller can do logic on that to do some stuff.
The sample code also receive on/off command from controller and emits IR signal depending on it.I use this node to turn on/off sony sound system (15bit sony protocol) and benq projector (NEC protocol) together beside htpc(via wol). Openhab rule send 8byte IR codes as V_IR_Send to node and node emits the required IR codes.

Hi, I am having an issue compiling the sketch and was wondering if you had any input or could help me out, This is what I get back when I try to compile;

@ramoncarranza
Compiler complains about not understanding decode_type_t. It should be defined in .h file or maybe you defined it in sketch but there is a problem definetly.
Can you post whole sketch and IR library and error message if any other so we can check and test.By the way, I installed IRremote.h (v2.1.0) via library manager, and default sketch compiled without error on IDE 1.6.5 win7 and IDE 1.6.10 linux mint 17.

Re: 💬 Infrared Sender and Receiver
How do you enter the raw IR codes, i.e. those that aren't covered in the sketch? I have one through the receiver in the format - 23784 1800 -800 950 -1700 1800 -850 900 -850 950 -1700 1800 -850 900 -850 900 -850 950 -800 950 -850 900

@ramoncarranza When I went and looked where the library manager installed the IRremote lib(for me C:\Users\User\Documents\Arduino\libraries), it had given it an odd name like arduino_294267. I renamed it to IRremote and the issue went away.
