  • 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 ?



  • @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:

  • @Talat-Keleş
    thank you my friend



  • This post is deleted!


  • 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 ?



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



  • Hi @Reza ,
    Did you solve this problem?



  • @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?



  • 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

    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.



  • 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?



  • This post is deleted!


  • 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.



  • @Talat-Keleş
    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



  • @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.



  • 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???



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



  • 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)



  • 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?



  • Hi Running this code I get the following errors anyone know why?

    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?

  • 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"

    My material in place:
    Domoticz V. 3.8153 sur Raspberry PI 3
    Gateway USB MySensor V. 2.1.1 on Arduino Nano
    IRSensor V. 2.0.0 on Arduino Nano

    For information in the domoticz log:

    -The node is well detected

    2017-12-28 09:07:12.553 MySensors: Node: 7, Sketch Name: IR Rec/Playback
    2017-12-28 09:07:12.554 MySensors: Node: 7, Sketch Version: 2.0

    -When I send a pre-recorded order with the remote control

    2017-12-28 09:07:59.346 (MySensor) Light/Switch (IR Command)

    -When I activate the device in Domoticz

    2017-12-28 09:08:29.835 User: Admin initiated a switch command (149/IR Command/Off)
    2017-12-28 09:08:29.836 Error: MySensors: Light command received for unknown node_id: 6

    Someone would have any idea?

    Thanks for your help.

  • 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.
