is this a learning mode module ?
how use this module for learn my ir codes ?

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.

@Talat-Keleş
I mean that every ir codes ( each brand for TV , audio . . . ) can learn to this node ( similar to zwave IR extender) and use OR in sketch we most write every codes that i will use ?!
if this is a learning mode module !how many codes can learn to this ? ) for example zwave ir extender give 20 key ! or global cashe give many codes ?!

@Reza

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 ?

Talat Keleş

@Reza

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.

Simple button based TV Control with OH

Here is my node sketch:

TON RIJNAARD

is it possible to use with domoticz?

Reza

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

domoticz doesn't support this ?! i test this and i see domoticz wont detect this node

zhangzc

Hi @Reza ,
Did you solve this problem?

Reza

@zhangzc

hi , no . i can not use this device with domoticz

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?

Wackid

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

Wackid

@Wackid

I know how to read out the IR signals. And to put it in the sketch manually. But I really like to make use of the record function.
Where and how do I make the node to set it in learn function.

tiana

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?

I use this IR transmitter toward my LG Tv and it works at a distance of ~3.5 m, but IR LED must be well pointed to the Tv, otherwise it doesn't work.

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;
0_1483733093476_upload-fba9c55f-1a02-4b17-b7ff-bc75aadb47d1

@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

pete1450

@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.

hashem25

I am confused i see the decode in my com monitor and i see the ir node in my domoticz but there is no data???

wilson64

Can I use MQTT & Node Red to make this work, if yes can somebody show me how

Mitja Blazinsek

ok i record ir code 240E4F17 from my AC remote hov can i sent this code from my controler to IR node and request from node to sent that code (on/off) AC i was trying with raw mesage but i dot know what to send (Type/ Sub type , Acknowledge/ Payload)

dbemowsk

So, I am thinking of building this and I noticed that the documentation says that you may need a mega to do this. Is a mega required, or will the code work with a nano or an uno?

Trying to compile the Infrared Sender and Receiver sketch to be used on a WeMos D1 Mini Pro (ESP8266) but I get the following error:

Seems like the saving/reading to/from Eeprom is handled differently when it comes to ESP8266.
So what do I need to change in order to get the sketch to compile?

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Changed for MySensors usage by Bart Eversdijk
 * Version 1.1 - Added option to record manual presets up to 240
 * Version 2.0 - Migrated to MySensrors version 2.0
 * 
 * DESCRIPTION
 *
 * IRrecord: record and play back IR signals as a minimal 
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * An IR LED must be connected to the output PWM pin 3.
 *
 *
 * The logic is:
 * If a V_IR_RECORD is received the node enters in record mode and once a valid IR message has been received 
 * it is stored in EEPROM. The first byte of the V_IR_RECORD message will be used as preset ID 
 * 
 * If a V_IR_SEND the IR message beloning to the preset number of the first message byte is broadcasted

This sketch does't work. I have tried it with arduino nano and arduino mega. It works only as a ir reader with monitor.

In this code domoticz says that there is a problem with presenting the child. I have change the code in order to present it properly in domoticz.
//MyMessage msgIrReceive(CHILD_ID, V_IR_RECEIVE);
//MyMessage msgIrRecord(CHILD_ID, V_IR_RECORD);
MyMessage msgIrReceive(CHILD_ID, S_IR);
MyMessage msgIrRecord(CHILD_ID, S_IR);

All dependencys of V_IR_RECEIVE and V_IR_RECORD should also be changed. Just search the code for V_IR_RECEIVE and V_IR_RECORD, then replace it with S_IR.

I am having trouble doing IRSensor with domoticz.
After pouring the scketch into the arduino, saved my codes and
to check that it worked well with MYSController, here's what
I obey when I activate the device under Domoticz:

"error sending command to the switch, please verify device/hardware"

Someone would have any idea?

Thanks for your help.

@mash please don't post the same question in multiple places. Posting in multiple places will divide the discussion, causing people to waste their time.

If anyone has any ideas on how to help @mash, do not reply here. Reply in https://forum.mysensors.org/topic/8793/problem-with-irsensor-and-domoticz instead.

sorry, forgave me I would not do it again

Hello
Using the example sketch from the main thread, I managed to program a few pilot buttons in the domotic. (IR codes are of course entered in the section: IRCode PresetIRCodes [] = (...).
I would, however, "upload" a few IR codes to Domoticz, which would control my TV and AV via the IR diode from the Domoticz level.

In this example, there is the sendRCCode () function, which, in theory, sends an IR code (previously uploaded to Domoticz) via IR diode, if of course it will get
message.type == V_IR_SEND.

I added an additional declaration:
MyMessage msgIrSend (CHILD_ID, V_IR_SEND);
but in Domoticz there was no additional Device that would be responsible for sending IR codes.
I think I probably need to do an additional Dummy Switch, which will send an IR signal transmission command to the gateway / node using JSON.
I'm thinking about it for a long time and I have no idea how to do it in DOMOTICZ.
Please help me how to do it.

Hi All, has anyone had any success porting this IR sketch example to work with the IRremoteESP8266 library? I am not getting much further than @korttoma.

Thanks CV8R.

Hi everyone I am trying to setup a node to control my A/C unit and am having some trouble.

I am using these libraries
MySensors at version 2.3.2
IRremote at version 2.2.3

My hardware is
Arduino mega 2560
Nrf24

The problem is if i press a button on the remote i get this on the console

Received : -1 UNKONWN B5E9B811 (32 bits)
Raw (38): -17746 8350 -4250 500 -1600 550 -1550 550 -1550 550 -500 450 -1650 550 -600 500 -1550 500 -1550 600 -4100 550 -1550 600 -1500 500 -550 600 -1500 550 -550 550 -500 550 -500 550 -500 650

So i uncommitted this

// Raw or unknown codes requires an Arduino with a larger memory like a MEGA and some changes to store in EEPROM (now max 255 bytes)
// #define IR_SUPPORT_UNKNOWN_CODES

to this

// Raw or unknown codes requires an Arduino with a larger memory like a MEGA and some changes to store in EEPROM (now max 255 bytes)
 #define IR_SUPPORT_UNKNOWN_CODES

but now if i compile the code i get this error

exit status 1

@catchra in bool storeRCCode(byte index) you need to change

#else
    return false;
  }
#endif

to

#else
    return false;
#endif
  }

The clue was in the verification output:


C:\Users\Micke\AppData\Local\Temp\arduino_modified_sketch_286541\sketch_may25a.ino: In function 'bool storeRCCode(byte)':

Am I missing something?

@bollarcreets, I am afraid that the script has never been adapted to the evolution of the IRRemote library.
If you take library version 2.2.3, the script will compile.

If you take the source code from the latest version 2.8.1 you will also see that the typedef enums AIWA_RC_T501 and MITSUBISHI are commented out.

If you want to run this example script with the latest version of the library, you will need to analyse and understand the script in order to modify it...

@evb said in Infrared Sender and Receiver:

That does indeed work - thanks!

What's the best way to get the tutorial edited to include this information?

@bollarcreets I've added a note in the instructions. Please let me know if you think it could be reworded or put someplace else to make it clearer.

@mfalkvidd thanks, that change is all that's needed I think. Thanks to you and @evb for the prompt help!
